Frequently Asked Questions

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

A: 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 Change Healthcare 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 such as Postman, or test APIs using your own development console.
