Frequently Asked Questions

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

A: Yes, you can use our sandbox environment before signing a contract. The login requires a separate set of credentials that you can get 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, use an application like Postman, or test APIs using your own development console.
