Frequently Asked Questions

Which payers can I submit prior authorization requests to?

The payer list can be found here:

Prior authorization requests can be submitted to any payer that has a value in the Authorization Verification Inquiry Connection column.

Do you have a sandbox that I can test before signing a contract?

We do! You can use our Sandbox environment even before signing a contract. It requires a separate set of secure credentials which you can obtain from your Optum representative. After receiving your client_id and client_secret for our Sandbox environment, you can test the API in our interactive documentation. The interactive documentation can be found by following the "Return to the API" button above.

Are there any test responses available in the Sandbox?

Yes, there are test responses available in the Sandbox environment. See this page for more details Sandbox Test Responses.
