To refresh expired OAuth tokens, apply a server-side workflow using the refresh_token grant in Supabase Edge Functions, ensuring concurrency-safe row locking to prevent simultaneous rotation errors and maintain continuous authentication.

Refresh-token rotation fails during concurrent requests because multiple processes attempt to use or rotate the same token simultaneously. Enforcing concurrency-safe row locking ensures only one request rotates the token, while others wait, preventing invalidation and lockouts.

Yes, you can use Supabase Edge Functions to manage multi-practice OAuth token isolation by scoping tokens per practice and archive. This workflow requires server-only secret handling and proper nullish refresh-token persistence to maintain secure boundaries between practices.

The best way to handle 401 recovery for expired API tokens is to proactively intercept the error, execute a server-side refresh_token grant, and update the stored token. Include revoked-token classification to distinguish between tokens needing retry and those requiring re-authentication.

To persist a nullish refresh token safely during server-side rotation, handle the token update on the server within Supabase, ensuring empty or null values do not overwrite valid tokens. This prevents data loss during the refresh-token rotation process.

You should proactively renew access tokens before expiry when managing multiple practices or high-volume API calls. This approach avoids latency from 401 recovery workflows and ensures tokens are refreshed safely using server-side logic without interrupting user sessions.
