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

  1. 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.
  2. For QuickBooks Online accounting data request scope com.intuit.quickbooks.accounting (add openid/profile/email only if you also use OpenID Connect).
  3. Include a random state value to protect against CSRF; verify it matches when the user is redirected back.
  4. After the user approves, Intuit redirects to redirect_uri?code=<one-time code>&state=<your state>&realmId=<company id>.
  5. Validate state, extract the code, then exchange it at the token endpoint with grant_type=authorization_code.
  6. API docs: https://developer.intuit.com/app/developer/qbo/docs/develop/authentication-and-authorization/oauth-2.0
