Gain connectivity and flexibility with electronic claims transactions

Q: How can I test the APIs to explore further?
A: You can test the APIs from within our interactive documentation, use an application such as Postman, or use your own development platform. You use a separate Optum-issued secret pair for your production API work.
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.
Q: How do I get started with onboarding?
