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 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.

  • For testing, the Sandbox Rules as a Service Institutional API endpoint is as follows:

    https://sandbox.apigw.changehealthcare.com/medicalnetwork/institutionalclaims/advanced/v1/validation
  • For Raw X12 validation:

    https://sandbox.apigw.changehealthcare.com/medicalnetwork/institutionalclaims/advanced/v1/raw-x12-validation
  • API Healthcheck:

    https://sandbox.apigw.changehealthcare.com/medicalnetwork/institutionalclaims/advanced/v1/healthcheck
  • The Sandbox endpoint URL for authorization tokens is as follows:

    https://sandbox.apigw.changehealthcare.com/apip/auth/v2/token

Authorization tokens have a lifespan of 3600 seconds (1 hour) in the Sandbox environment.

NOTE: All JSON fields in a Sandbox request body must use a predefined value to have a successful response in the Sandbox.

If you don't use predefined Sandbox values, you will receive errors like the following:

{
    "errors": [
        {
            "field": "claimInformation.claimSupplementalInformation",
            "description": "Please use predefined canned users for non-prod environments: claimNumber was not predefined."
        },
        {
            "field": "subscriber",
            "description": "Please use predefined canned users for non-prod environments: policyNumber was not predefined."
        },
        {
            "field": "claimInformation",
            "description": "Please use predefined canned users for non-prod environments: patientControlNumber was not predefined."
        }
    ]
}
