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.

Try our Postman Collection!

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."
        }
    ]
}
