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
Use a freshly obtained or refreshed access_token and the company's realmId.
GET https://quickbooks.api.intuit.com/v3/company/{realmId}/companyinfo/{realmId} with header 'Authorization: Bearer <access_token>'.
Expect HTTP 200 with a CompanyInfo object containing CompanyName, LegalName, Country, and other metadata.
Use a successful response as a smoke test that OAuth setup, the token, and the realmId are all correct.
On 401, refresh the token and retry; on 400/404 re-check the realmId path segments.

Known gotchas
realmId appears twice in this path — once for /company/{realmId}/ and once as the entity id.
This is a lightweight call, ideal for a connectivity health check during onboarding tests.
Sandbox companies return sandbox metadata; don't expect production values.
