In-depth guide
QuickBooks OAuth refresh token rotation — the full failure-mode walkthrough related to developer.intuit.com, checked against official docs, with linked verified routes.
Documented steps
Classify errors by which endpoint (token endpoint vs QBO API) returns them.
invalid_grant from the token endpoint usually means the refresh token or authorization code was already used or expired — obtain a new refresh token via re-authorization.
Unauthorized / HTTP 401 on API calls means the access token expired or is invalid — call grant_type=refresh_token and retry the request once.
429 rate-limit responses should be retried with backoff, honoring any returned Retry-After header.
HTTP 400 on the tokens/revoke endpoint means revocation failed — surface it to the user rather than swallowing it.
Log Intuit request/response IDs (e.g. intuit_tid) to correlate support tickets.

Known gotchas
A stale stored refresh_token is the most common cause of invalid_grant — always persist the newest one.
Retrying with an already-expired access token keeps failing; refresh first, then retry exactly once to avoid duplicate side effects.
Do not treat unknown extra fields in the token response as errors.
