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
Send the user to the Intuit authorization endpoint (https://appcenter.intuit.com/connect/oauth2) with query params client_id, response_type=code, scope, redirect_uri, and state.
For QuickBooks Online accounting data request scope com.intuit.quickbooks.accounting (add openid/profile/email only if you also use OpenID Connect).
Include a random state value to protect against CSRF; verify it matches when the user is redirected back.
After the user approves, Intuit redirects to redirect_uri?code=<one-time code>&state=<your state>&realmId=<company id>.
Validate state, extract the code, then exchange it at the token endpoint with grant_type=authorization_code.
API docs: https://developer.intuit.com/app/developer/qbo/docs/develop/authentication-and-authorization/oauth-2.0
Known gotchas
The redirect_uri must exactly match the one registered in Keys & OAuth or Intuit rejects the request.
Capture realmId from the redirect query and store it per user alongside the tokens.
The authorization code is single-use and short-lived — exchange it immediately.
