In `@src/content/docs/integrate/third-party-tools/kinde-and-convex.mdx`:
- Around line 296-306: The one-time upsert guard incorrectly sets
hasUpserted.current = true before storeUser completes and never resets on
sign-out; update the useEffect that references hasUpserted, isAuthenticated,
user, and storeUser so that: (1) when !isAuthenticated || !user you reset
hasUpserted.current = false, and (2) only set hasUpserted.current = true after
the Promise returned by storeUser resolves successfully (handle errors without
flipping the flag). This ensures retries on failure and re-syncs after a new
sign-in.
- Around line 54-58: The quickstart step currently installs only "convex" but
the guide later imports "@kinde-oss/kinde-auth-react" (seen in imports like
`@kinde-oss/kinde-auth-react`), causing module-not-found errors; update the
install instruction (the step that runs npm install convex) to also install
"@kinde-oss/kinde-auth-react" (e.g., npm install convex
`@kinde-oss/kinde-auth-react`) so fresh setups have both dependencies available.
- Around line 138-139: The auth flow in useAuthFromKinde() is using
getAccessToken() but Convex custom auth requires the ID token; update
useAuthFromKinde() to call getIdToken() instead of getAccessToken(), pass that
ID token where the Convex auth payload is constructed (the value used for
applicationID/aud checks), and ensure any variable names or comments reflect
that this token is the ID token used for identity/authentication.

82-94:⚠️ Potential issue | 🟠 MajorInconsistency between
audienceprop and ID token usage.The
KindeProviderincludesaudience="convex"(line 87), but theuseAuthFromKindehook usesgetIdToken()(lines 110, 119). Theaudienceprop only affects access tokens, not ID tokens, making it misleading here.Based on the retrieved learning, there are two valid approaches:
- Access token approach: Use
getAccessToken()withaudience="convex"and setapplicationID: "convex"inauth.config.ts- ID token approach: Use
getIdToken()withapplicationIDmatching the Kinde client ID (no custom audience needed)The current code mixes both approaches. To maintain consistency:
Option A: Remove the extraneous audience prop (if using ID token approach)
<KindeProvider clientId="your_kinde_client_id" domain="https://your_kinde_business.kinde.com" logoutUri={window.location.origin} redirectUri={window.location.origin} - audience="convex" >Option B: Switch to access token approach per retrieved learning
Update
useAuthFromKinde.ts:- const { isLoading, isAuthenticated, getIdToken } = useKindeAuth(); + const { isLoading, isAuthenticated, getAccessToken } = useKindeAuth(); const fetchAccessToken = useCallback( async ({ forceRefreshToken, }: { forceRefreshToken: boolean; }) => { void forceRefreshToken; try { - const response = await getIdToken(); + const response = await getAccessToken(); return response as string; } catch { return null; } }, - [getIdToken], + [getAccessToken], );And update
auth.config.ts:- applicationID: "your_kinde_client_id", + applicationID: "convex",Based on learnings: In Kinde + Convex integrations, use
getAccessToken()instead ofgetIdToken()because the access token requested withaudience="convex"has"aud": ["convex"]which matches Convex'sapplicationIDvalidation.Also applies to: 109-131
