Add Comments to Your LMS via LTI 1.3

1. Prijavite se na FastComments i otiđite na vašu stranicu za konfiguraciju LTI 1.3.
2. (Opcionalno) Izaberite platformu sa koje se povezujete iz padajućeg menija Platforma - to podešava prikazni naziv, ali Automatsko otkrivanje radi dobro.
3. Kliknite Generiši URL. Pojaviće se jednokratni URL za registraciju (važi 30 minuta, za jednokratnu upotrebu).
4. U vašem LMS-u otvorite ekran za dinamičku registraciju LTI 1.3 i nalepite URL u polje Tool initiation registration endpoint (ili ekvivalentno). Pošaljite.
5. Vaš LMS poziva FastComments, razmenjuje ključeve i kreira integraciju. Iskočni prozor se sam zatvara kada se proces završi.
6. Vratite se u FastComments — nova konfiguracija se pojavljuje u tabeli Postojeće konfiguracije. Alat je sada dostupan u vašim kursevima unutar LMS-a.

FastComments LTI 1.3 je testiran na:

• D2L Brightspace (bilo koja verzija sa LTI Advantage)
• Moodle 4.0+ (External Tool plugin, LTI Advantage)
• Blackboard Learn (SaaS i Ultra)
• Sakai (verzije sa podrškom za LTI Advantage)
• Schoology (Enterprise, Dynamic Registration gde je dostupno)

Bilo koji drugi LMS koji implementira IMS LTI 1.3 Advantage specifikaciju sa Dynamic Registration takođe bi trebalo da radi - izaberite Other LTI 1.3 platform iz padajućeg menija platforme kada generišete svoj URL za registraciju (preuzmite ovde).

Canvas LMS koristi drugačiji tok podešavanja (per-developer-key configuration JSON umesto Dynamic Registration). Pogledajte namenski vodič za instalaciju Canvas LMS-a.

Idite na LTI 1.3 konfiguraciju

Prijavite se na FastComments i idite na vašu stranicu za LTI 1.3 konfiguraciju.

Ako vaš nalog još nema LTI pristup, videćete "LTI nije omogućen za ovaj nalog" - kontaktirajte podršku da ga omoguće na vašem planu.

Izaberite platformu (opciono)

Pod Generiši dinamički URL za registraciju, koristite padajući meni Platforma da kažete FastComments kojoj LMS platformi se povezujete:

• D2L Brightspace
• Moodle
• Blackboard Learn
• Sakai
• Schoology
• Druga LTI 1.3 platforma

Takođe možete ostaviti na Automatsko otkrivanje. Platforma se čita iz vašeg LMS-ovog openid-configuration tokom registracije; padajući meni samo postavlja oznaku koja će se prikazati za nastalu konfiguraciju.

Generišite URL

Kliknite Generiši URL. FastComments kreira jednokratni token za registraciju i prikaže vam URL koji izgleda ovako:

https://fastcomments.com/lti/v1p3/register/<long-token>

Kopirajte ga. Ovaj URL:

• Je za jednokratnu upotrebu - nakon što vaš LMS uspešno pozove URL, token se potroši.
• Ističe posle 30 minuta ako se ne iskoristi.
• Treba ga držati privatnim - svako ko ima URL može registrovati alat za vaš tenant u roku od tih 30 minuta.

Postojeće konfiguracije

Kada se registracija uspešno završi, nova konfiguracija se pojavljuje u tabeli Postojeće konfiguracije na istoj stranici, sa svojom Platformom, Issuer-om, Client ID-jem i Statusom. Možete izbrisati konfiguracije iz ove tabele ako ikada budete morali da se odregistrujete.

D2L Brightspace izlaže dinamičku registraciju kroz LTI Advantage administratorski interfejs. Trebaće vam administratorski pristup.

Otvorite ekran za registraciju

1. Prijavite se u vašu Brightspace instancu kao administrator.
2. Idite na Admin Tools > Manage Extensibility > LTI Advantage.
3. Kliknite Register Tool. (Direktan URL je https://<your-brightspace-host>/d2l/le/ltiadvantage/registrations/create.)

Zalepite URL

Videćete obrazac za registraciju. Ključno polje je Tool initiation registration endpoint (neke verzije Brightspace-a ga nazivaju "Tool Initiation Registration URL").

Zalepite FastComments registration URL (nabavite ga ovde) u to polje. Ostavite ostala polja prazna — FastComments će ih automatski popuniti tokom postupka razmene pri registraciji.

Kliknite Register.

Odobrite alat

Brightspace otvara skočni prozor koji komunicira sa FastComments, razmenjuje ključeve i prikazuje ekran za potvrdu. Skočni prozor se sam zatvara kada se registracija završi.

Novi alat će se pojaviti na listi LTI Advantage alata. Podrazumevano Brightspace označava nove alate kao disabled — prebacite prekidač na enabled da bi vaši kursevi mogli da ga koriste.

Dodajte deployment

U Brightspace-u, LTI alati zahtevaju deployment pre nego što mogu biti korišćeni u kursevima:

1. Otvorite novo registrovani FastComments tool.
2. Kliknite View Deployments > New Deployment.
3. Dajte deployment-u ime (npr. "FastComments - All Courses"), izaberite organizacione jedinice u kojima treba da bude dostupan, i sačuvajte.

Nakon prvog pokretanja preko ovog deployment-a, FastComments prikači deployment_id na svoj zapis konfiguracije — naredna pokretanja iz drugog deployment-a u okviru istog klijenta biće odbijena osim ako se ponovo ne registrujete.

Koristite Moodle? Takođe objavljujemo poseban Moodle plugin za FastComments sa bližom integracijom nego LTI 1.3 (grade sync hooks, dublje izveštavanje aktivnosti, nativni Moodle interfejs za podešavanja). Pogledajte Vodič za instalaciju Moodle plugina. LTI 1.3 flow ispod je pravi izbor ako želite jedinstvenu registraciju koja pokriva i druge LMS-ove, ili ako vaš Moodle administrator neće instalirati dodatke trećih strana.

Moodle 4.0+ podržava LTI 1.3 Dynamic Registration kroz dodatak External Tool.

Otvorite ekran za upravljanje alatima

1. Prijavite se u Moodle kao administrator sajta.
2. Idite na Site administration > Plugins > Activity modules > External tool > Manage tools.

Nalepite URL

Videćete karticu označenu Tool URL. Nalepite URL za registraciju FastComments (preuzmite ga ovde) u tekstualno polje i kliknite Add LTI Advantage.

Moodle otvara ekran za registraciju koji prikazuje identitet alata i dozvole koje zahteva. Pregledajte i kliknite Activate (ili Register, u zavisnosti od verzije Moodla).

Iskakajući prozor se zatvara kada se registracija završi; novi FastComments alat pojavljuje se u listi Tools sa statusom Active.

Učinite ga dostupnim

Po defaultu Moodle dodaje nove alate na listu "Course tools" ali ih ne prikazuje u izborniku aktivnosti. Da biste omogućili FastComments na nivou kursa:

1. Kliknite ikonu zupčanika na FastComments pločici.
2. Ispod Tool configuration usage, izaberite Show in activity chooser and as a preconfigured tool.
3. Sačuvajte.

Instruktori sada mogu dodati FastComments u bilo koji kurs putem Add an activity or resource > FastComments.

Blackboard Learn SaaS i Ultra podržavaju LTI 1.3 Dynamic Registration.

Otvorite ekran provajdera alata

1. Prijavite se u Blackboard kao sistem administrator.
2. Idite na Administrator Panel > Integrations > LTI Tool Providers.
3. Kliknite Register LTI 1.3 / LTI Advantage Tool.

Ako vidite samo "Register LTI 1.1 Provider", vaša verzija Blackboard-a još ne podržava LTI 1.3 — nadogradite ili kontaktirajte Blackboard podršku.

Nalepite URL

Nalepite FastComments registration URL (preuzmite ovde) u polje Client ID / Registration URL (oznake se razlikuju po verziji). Pošaljite.

Blackboard obavlja registracioni handshake sa FastComments i prikazuje ekran za potvrdu.

Odobrite i omogućite

Blackboard označava novo registrovane alate kao Approved but excluded podrazumevano:

1. Pronađite unos za FastComments na listi provajdera alata.
2. Otvorite meni i izaberite Edit.
3. Postavite Tool Status na Approved.
4. U okviru Institution Policies, pregledajte koji se korisnički podaci šalju (name, email, role). Sačuvajte.

Alat je sada dostupan instruktorima kada dodaju sadržaj na kurseve.

Sakai

Sakai podržava LTI 1.3 Dynamic Registration na izdanjima koja imaju LTI Advantage. Iz Administration Workspace:

1. Prijavite se kao Sakai administrator i otvorite Administration Workspace.
2. Izaberite External Tools > Install LTI 1.3 Tool.
3. Nalepite FastComments registration URL (preuzmite ovde) i pošaljite.
4. Odobrite alat kada se handshake završi.

Alat će se potom pojaviti pod External Tools i mogu ga dodati održavaoci sajtova.

Schoology

Schoology Enterprise instance podržavaju LTI 1.3, ali dostupnost Dynamic Registration varira u zavisnosti od deploymenta. Obratite se svom Schoology account manageru.

Ako Dynamic Registration nije dostupna na vašoj Schoology instanci, moraćete da konfigurišete integraciju ručno koristeći sledeće endpoint-e:

• OIDC Login URL: https://fastcomments.com/lti/v1p3/login
• Target Link URL: https://fastcomments.com/lti/v1p3/launch
• Public Keyset URL (JWKS): https://fastcomments.com/lti/v1p3/jwks
• Redirect URLs: https://fastcomments.com/lti/v1p3/launch

Nakon što vam Schoology dodeli Client ID i Deployment ID, kontaktirajte FastComments podršku da registrujete konfiguraciju na vašem tenant-u.

Other LTI 1.3 Platforms

Bilo koji LMS koji prati IMS LTI 1.3 Advantage spec trebalo bi da radi sa istim registration URL (preuzmite ovde). Potražite podešavanje označeno kao "Dynamic Registration", "Tool Registration URL", "Tool initiation registration endpoint", ili slično.

Ako vaša platforma podržava samo ručno podešavanje LTI 1.3, koristite četiri endpoint-a navedena u odeljku Schoology iznad i kontaktirajte podršku da finalizujete postupak.

Ova stranica objašnjava kako dodati FastComments u Brightspace kurs nakon što je administrator registrovao alat i kreirao deployment. Ako alat još nije registrovan, prvo pogledajte D2L vodič za registraciju.

FastComments ugrađen kao temu jedinice u Brightspace-u

Brightspace isporučuje dva iskustva za autorstvo sadržaja: Classic Content i New Content Experience (takođe nazvano Lessons). Oba omogućavaju FastComments, ali se putanje kroz meni razlikuju. Svaki odeljak ispod pokriva oba gde se razlikuju.

Locate the FastComments Tool

Alat FastComments se pojavljuje na dve lokacije unutar uređivača sadržaja kursa:

1. U activity picker-u, do kojeg se dolazi preko Add Existing dugmeta u modulu/jedinici (označeno kao Add Existing Activities u starijim verzijama Brightspace-a). FastComments se pojavljuje direktno u picker-u u aktuelnim izdanjima Brightspace-a; starije verzije ga ugrađuju pod External Learning Tools podmeni. Bilo koji put dodaje FastComments kao zasebnu temu.
2. U Insert Stuff dijalogu unutar HTML uređivača, pod LTI Advantage. Ovo ugrađuje FastComments inline u HTML temu putem LTI deep linking toka.

Ako se FastComments ne pojavljuje ni u jednom picker-u, deployment nije omogućen za org unit koji drži kurs. Zamolite vašeg Brightspace administratora da otvori Admin Tools > Manage Extensibility > LTI Advantage > FastComments alat > View Deployments, otvori deployment i doda org unit kursa (ili roditeljski org unit) pod Org Units.

Add FastComments as a Topic in a Module

Classic Content:

1. Otvorite kurs i kliknite Content u navigacionom baru.
2. Izaberite modul koji bi trebalo da sadrži diskusiju (ili kreirajte jedan preko Add a module).
3. Kliknite Add Existing (stariji Brightspace: Add Existing Activities > External Learning Tools).
4. U picker-u, kliknite FastComments. Brightspace kreira temu u modulu i vraća vas na pregled sadržaja.
5. Kliknite novu temu. Preimenujte je u nešto opisno kao FastComments Discussion koristeći inline editor naslova.

New Content Experience (Lessons):

1. Otvorite kurs i kliknite Content.
2. Otvorite jedinicu i lesson koji bi trebalo da sadrže diskusiju.
3. Kliknite Add > Existing Activity i izaberite FastComments (stariji Brightspace: ugnježdeno pod External Learning Tools).
4. Aktivnost je dodata u lesson.
5. Kliknite na naslov aktivnosti da biste je preimenovali.

Prvi put kad bilo koji korisnik (instruktor ili student) otvori temu, FastComments inicijalizuje thread za taj resource link. Thread je vezan za resource link ID, tako da preimenovanje ili premestanje teme ne menja koji thread se učitava.

Embed FastComments Inline in an HTML Topic

Koristite ovaj tok kada želite da se komentari pojave ispod čitanja, videa ili drugog sadržaja unutar iste stranice teme, umesto kao zasebna tema.

1. Otvorite ili kreirajte HTML temu u modulu/lesson-u.
2. Kliknite Edit HTML da otvorite Brightspace HTML uređivač.
3. Postavite kursor tamo gde thread komentara treba da se pojavi.
4. Kliknite dugme Insert Stuff (ikonica slagalice u toolbar-u uređivača).
5. U Insert Stuff dijalogu, skrolujte do LTI Advantage i kliknite FastComments.
6. FastComments otvara deep linking picker. Potvrdite pozicioniranje (podrazumevana podešavanja rade za diskusije o sadržaju); kliknite Insert ili Continue.
7. Brightspace se vraća u HTML uređivač sa placeholder blokom koji predstavlja LTI launch. Kliknite Save and Close na temi.

Kada se tema učita, Brightspace zamenjuje placeholder iframe-om koji automatski pokreće FastComments preko LTI-a. Studenti vide thread diskusije inline.

Jedna HTML tema može držati više deep-linked FastComments ugradnji. Svaka ugradnja dobija svoj thread jer svaki deep link proizvodi različit resource link ID.

Module Topic vs Inline Quicklink

Izaberite pristup module topic kada:

• Diskusija je primarna aktivnost za taj korak u modulu.
• Želite da tema bude vidljiva u Brightspace-ovom sadržaju, praćenju kompletiranja i Class Progress.

Izaberite pristup inline embed kada:

• Komentari treba da stoje ispod drugog sadržaja na istoj stranici.
• Ne želite zaseban item koji se prati u tabeli sadržaja.

Visibility, Draft, and Release Conditions

Nova FastComments tema je po defaultu vidljiva studentima. Da je sakrijete dok je podešavate:

1. U uređivaču sadržaja, kliknite naslov teme (Classic) ili meni sa tri tačke na aktivnosti (New Content Experience).
2. Podesite status na Draft (Classic) ili isključite Visibility (New Content Experience).

Draft teme su nevidljive studentima. Instruktori i asistenti i dalje ih vide sa oznakom "Draft".

Da ograničite temu na određenu grupu ili sekciju:

1. Otvorite temu.
2. Kliknite meni naslova teme > Edit Properties In-place (Classic) ili Edit > Restrictions (New Content Experience).
3. Pod Release Conditions, kliknite Create.
4. Izaberite Group enrollment ili Section enrollment, izaberite grupu/sekciju i sačuvajte.

Release conditions se slažu sa FastComments-ovim sopstvenim mapiranjem uloga. Studenti koji ne mogu da vide temu nemaju LTI launch.

What Students See on First Launch

Kada student klikne temu (ili učita HTML temu sa ugradnjom):

1. Brightspace obavlja LTI 1.3 launch u pozadini.
2. FastComments prima studentovo ime, email, avatar URL i LMS ulogu, i automatski ga prijavljuje. Nema FastComments prijavnog prompta.
3. Thread komentara za taj resource link se prikazuje unutar Brightspace iframe-a.

Mapiranje uloga pri launch-u:

• Brightspace Administrator postaje FastComments admin za thread (puni moderacioni pristup: brisanje, banovanje i pristup konfiguraciji).
• Brightspace Instructor postaje FastComments moderator (pinovanje, skrivanje, brisanje, banovanje).
• Sve druge uloge (Learner, TeachingAssistant, itd.) postaju standardni komentatori.

Komentari su pripisani studentovom Brightspace nalogu. Ako student izmeni ime ili avatar u Brightspace-u, sledeći LTI launch sinhronizuje promenu.

Iframe Height and Resize

FastComments emituje org.imsglobal.lti.frameResize postMessage pri svakom renderu threada i pri promenama sadržaja (novi komentar, proširenje odgovora). Brightspace sluša ovu poruku i podešava visinu iframe-a tako da thread nije obrezan i da se ne prikazuje unutrašnji scrollbar.

Ako iframe ostane na fiksnoj maloj visini:

• Potvrdite da je kurs učitan preko HTTPS-a. Brightspace-ov postMessage listener odbija mixed-content frame-ove.
• Potvrdite da nijedno browser proširenje ne blokira postMessage kanal.
• Za inline ugradnje u HTML temi, okolni HTML ne sme umotavati iframe u kontejner fiksne visine. Uklonite bilo koji inline style="height: ..." iz roditeljskog elementa.

Brightspace-Specific Gotchas

Tool not showing in the Add Existing picker. Deployment nije omogućen za org unit ovog kursa. Administrator treba da doda org unit (ili roditelja) na listu Org Units u deployment-u. Sama registracija alata nije dovoljna; deployment određuje koji kursevi vide alat.

deployment_id mismatch on launch. FastComments TOFU-pin-uje prvi deployment_id koji vidi za registraciju. Ako administrator obriše originalni deployment i kreira novi, launch-ovi iz novog deployment-a se odbijaju sa greškom o neusaglašenosti deployment-a. Rešenje je ponovo registrovati FastComments (generišite novi registration URL (get it here) i pokrenite Dynamic Registration ponovo); stari zapis konfiguracije se zamenjuje.

Tool launches but shows "Invalid LTI launch". Kurs se nalazi u drugom tenant/org strukturi nego što deployment pokriva, ili je deployment onemogućen nakon registracije. Ponovo proverite Admin Tools > Manage Extensibility > LTI Advantage > FastComments > Enabled prekidač i listu org unit-a deployment-a.

Names and roles missing inside FastComments. Brightspace šalje LTI launcheve sa Names and Role Provisioning Services (NRPS) claim-ovima. Ako je kurs nadograđen sa starijeg LTI 1.1 linka, launch može da nema name i email claim-ove. Ponovo dodajte FastComments temu preko Add Existing (ne migrirajte stari link) tako da launch koristi LTI 1.3.

Embed shows a login screen instead of auto-SSO. HTML tema je umetnuta kao običan <iframe> koji pokazuje na FastComments umesto preko Insert Stuff > LTI Advantage. Obični iframe-ovi preskaču LTI launch i vode korisnike na javnu FastComments stranicu. Obrišite iframe i ponovo umetnite kroz Insert Stuff tok.

Once an administrator has registered FastComments as an LTI 1.3 Advantage tool and approved the institution policies, instructors add it to courses through the standard Blackboard placement points. The exact steps differ between Ultra Course View and Original Course View, so both are covered below.

Ultra Course View

Ultra Course View is the default in Blackboard Learn SaaS as of 2026.

1. Open the course and go to the Course Content page.
2. Hover or tap where you want the comment thread to land in the outline and click the purple + (Add content) button.
3. Choose Content Market. The Content Market panel lists every approved LTI tool and Building Block placement for your institution.
4. Find the FastComments tile and click it. Blackboard creates a content item at the position where you opened the + menu.
5. The item lands in the outline as a "Visible to students" entry by default for instructors who have Hide from students off as their personal default. If your default is Hidden, the item is created hidden and you flip the visibility selector on the item row when you're ready.
6. To rename the item, click the title in the outline and type a new label. The title students see in the outline is independent of the FastComments thread identifier, so renaming is safe at any time.

If you don't see Content Market as an option, your institution has the placement hidden. You also reach the same picker through More tools in the same + menu under the LTI Tools group.

Original Course View

Original Course View is still supported in Learn SaaS and remains the primary experience for self-hosted Learn 9.1 sites on the Q4 2024 CU release line.

1. Open the course and enter a Content Area (for example, the default Information or Content area in the course menu).
2. Turn Edit Mode on with the toggle in the top-right of the page.
3. Click Build Content in the action bar.
4. Under the Learning Tools submenu, click FastComments. The Learning Tools submenu is populated from LTI 1.3 tool placements after an administrator registers the tool. If you don't see it, see the gotchas section below.
5. On the Create FastComments form, set:
   • Name: the label students see in the content area.
   • Description: optional text shown above the embedded thread.
   • Permit Users to View this Content: Yes/No availability toggle.
   • Track Number of Views: enable if you want Blackboard's per-item view statistics. FastComments runs its own analytics independently.
   • Date and Time Restrictions: optional Display After / Display Until windows.
6. Submit. The tool appears as a clickable item in the content area.

Embedding Inside an Item or Document

In both course views, instructors embed FastComments inline inside the body of an Item, Document, or any rich-text field through the Content Editor's LTI Advantage button.

Ultra Course View:

1. Create or edit a Document.
2. Click Add content inside the document body where you want the thread to appear.
3. In the editor toolbar, open the Insert content menu and click Content Market (the LTI Advantage / Deep Linking entry point).
4. Pick FastComments. FastComments returns a deep-link payload and Blackboard inserts an embedded block in the document body at the cursor position.
5. Save the document. Students see the thread rendered inline as they scroll past it.

Original Course View:

1. Edit any item with a rich-text body.
2. In the Content Editor toolbar, click the Add Content plus icon and choose Content Market (labeled Add Content from External Tool in older Q4 2024 CUs).
3. Pick FastComments. The editor inserts a placeholder block referencing the deep-linked resource.
4. Submit the item.

Each deep-link embed produces its own FastComments thread, so an Item with two embedded FastComments blocks has two independent comment streams.

Visibility, Release Conditions, and Group Restrictions

FastComments content items behave like any other Blackboard content item for the access control rules layered on top of them.

• Ultra: click the visibility selector on the row (Visible to students, Hidden from students, Conditional availability). Conditional availability supports date/time windows, performance rules against gradebook items, and member rules against course groups.
• Original: open the item's context menu and choose Adaptive Release or Adaptive Release: Advanced to gate the tool by date, membership, grade, or review status. Use Set Group Availability on the item to restrict to specific course groups.

FastComments respects whatever Blackboard's gate decides. If Blackboard hides the item from a student, the LTI launch never happens for that student and they don't appear in the moderator view.

Gradebook Behavior

FastComments does not report grades back over LTI Advantage Assignment and Grade Services. No grade column is auto-created for FastComments content items.

If your Blackboard tenant is configured to auto-create a gradebook column for every new content item regardless of grading metadata, an empty column appears anyway. To hide it:

• Ultra: open the Gradebook, click the column header, choose Edit, and turn off Show to students plus Include in calculations. Or use Delete if your institution permits column deletion for ungraded items.
• Original: open the Grade Center, click the column's chevron, choose Hide from Users (on/off), and optionally Hide from Instructor View under Column Organization.

What Students See

When a student opens the FastComments item or scrolls to an embedded block:

1. Blackboard launches the LTI 1.3 message to FastComments. The student is signed in via SSO using their Blackboard identity (name, email, avatar, role) without seeing a login form.
2. The comment thread renders in the iframe. Threading, replies, mentions, and reactions are all available based on the comment widget settings configured in FastComments.
3. Their comments are attributed to their Blackboard account. If the student edits their name or photo in Blackboard later, the next launch updates the FastComments profile.

Role mapping from Blackboard to FastComments:

• System Administrator and Course Builder map to FastComments admin.
• Instructor and Teaching Assistant map to FastComments moderator.
• Student, Guest, and Observer map to FastComments commenter.

Moderators see moderation controls (pin, hide, ban, delete) inline on every comment in the thread.

Thread Scoping

FastComments scopes each thread by (Blackboard host, course ID, resource link ID). Two FastComments items in the same course produce two threads. The same item copied across two course shells (for example, through course copy) produces two threads, because Blackboard issues a fresh resource link ID during the copy. To keep a shared thread across course copies, use Deep Linking with an explicit thread URN configured in FastComments before launching the copy.

Blackboard-Specific Gotchas

FastComments tile missing from the Build Content menu (Original) or Content Market (Ultra). The administrator approved the tool but left an institution policy blocking the relevant placement. Go to Administrator Panel > Integrations > LTI Tool Providers, edit the FastComments entry, and confirm both Course Content Tool (Original) and Course Content Tool - allow students / Deep Linking content tool (Ultra) placements are enabled. Save and refresh the course page.

"Tool not configured for this context" or "Tool is not deployed" error on launch. The deployment scope registered during dynamic registration doesn't match the institution context the course belongs to. In Blackboard's tool provider entry, verify the Deployment ID matches what FastComments shows on its LTI 1.3 Configuration page for this tenant. If they differ, delete the placement and re-run dynamic registration from a fresh registration URL (preuzmite ga ovde).

Iframe height looks fixed or content gets cut off. Some Blackboard tenants ship with a strict Content Security Policy that blocks the default LTI iframe-resize postMessage. FastComments emits both the Canvas-style lti.frameResize message and the IMS spec-form org.imsglobal.lti.frameResize message to maximize compatibility, but a tenant-level CSP override blocks the parent listener. Ask your administrator to confirm that *.fastcomments.com is on the LTI tool allowlist and that no custom CSP header is stripping postMessage events. Resize then works without further configuration.

Course copy duplicates threads. Blackboard course copy issues new resource link IDs for LTI placements, so copied courses start with empty threads. This is expected. If you need the copied course to inherit the original thread, set up Deep Linking with an explicit thread URN before copying, or contact FastComments support to remap thread IDs in bulk.

Student sees a generic Blackboard error on launch. The cause is a missing or stale email claim. Confirm the institution policy for FastComments has Role, Name, and Email Address enabled under User Fields to Send. Save, then launch again in a fresh browser session.

"Token za registraciju nije pronađen, istekao je ili je već iskorišćen"

Token u vašem registracionom URL-u (get it here) važi 30 minuta i može se iskoristiti samo jednom. Ako je vaš LMS potrošio više vremena od toga, ili je registracija ponovljena nakon uspeha, token će biti odbijen. Generišite novi URL na FastComments LTI 1.3 Configuration stranici i počnite ispočetka.

"Platform rejected registration"

Vaš LMS je odbio registracioni handshake. Najčešći uzroci:

• Tool already registered with the same client name. Neke platforme (posebno D2L) odbijaju drugu registraciju "FastComments" dok prethodna nije izbrisana. Uklonite stari alat u vašem LMS-u, zatim pokušajte ponovo.
• Wrong field in the LMS. Uverite se da ste zalepili URL u polje registration / tool initiation registration endpoint, a ne u polje launch URL ili login URL.
• The LMS doesn't actually support Dynamic Registration. Starije verzije Moodle-a i Blackboard-a oglašavaju LTI 1.3, ali dozvoljavaju samo ručnu konfiguraciju. Proverite dokumentaciju vaše platforme.

"Failed to fetch platform configuration"

FastComments nije mogao da pročita openid-configuration dokument vašeg LMS-a. Ovo je retko i obično znači da je LMS obezbedio neispravan ili nedostupan discovery URL. Kontaktirajte podršku vašeg LMS-a.

Launch shows "Configuration not found"

Ili je konfiguracija u FastComments obrisana, ili je pokretanje došlo od iss/client_id para koji ne prepoznajemo. Ako ste obrisali i ponovo registrovali, naložite vašem LMS-u da ukloni i ponovo doda FastComments alat kako bi dobio novi client_id.

Launch shows "Deployment not registered"

Pokrenuli ste FastComments iz Brightspace/Moodle/Blackboard deployment-a različitog od onog u kojem je prvi put pokrenut. FastComments zakači deployment_id pri prvom pokretanju kao bezbednosnu proveru. Da biste dodali novi deployment pod istim klijentom, kontaktirajte podršku — dodaćemo deployment ID u konfiguraciju.

Launch shows "Unsupported message_type"

LMS je poslao LTI poruku koju FastComments ne obrađuje (npr. LtiSubmissionReviewRequest). FastComments podržava samo standardni resource-link launch i deep-linking tokove. Obratite nam se ako vam je potreban dodatak specifičnog tipa poruke.

Iframe doesn't resize

Većina LMS-ova automatski prilagođava veličinu LTI iframe-ova. Ako vaš to ne radi, proverite da li podešavanja pokretanja u LMS-u omogućavaju alatu da šalje postMessage događaje roditeljskom okviru. FastComments emituje i Canvas-style (lti.frameResize) i IMS-spec (org.imsglobal.lti.frameResize) poruke za promenu veličine.
