API endpoints
For Arizona reporting, the state-specific methods — Create, Update, and Get — differ by form because each form has its own field structure.
A1-QRT (Arizona Withholding)
- Create – Create a new withholding filing for the state of Arizona (Form A1-QRT).
- Update – Update an A1-QRT form that was created but not yet transmitted.
- Get – Retrieve the information of a previously created A1-QRT form.
Common endpoints: For the remaining methods — List, Status, Transmit, RequestPdfUrls, and Delete, refer to the common endpoints shared across State Withholding reporting.
All endpoints require an OAuth 2.0 access token. Call the Auth method and pass the token as a Bearer token in the request header.
Testing & notifications
Before filing, you can simulate the entire verification flow in our Sandbox environment without submitting real data to state agencies.
As an alternative to polling the Status endpoint, you can configure a webhook for the Status Payroll Filings Status Change event type to receive automated status updates.
