Access Change Healthcare API

API URLs

You can access all Change Healthcare APIs using the following URLs. You will have a separate set of credentials for each URL:

• one set for the sandbox environment
• one set for production environment

Sandbox environment

https://sandbox.apigw.changehealthcare.com

This is a testbed where you can test our API capabilities.

• Sandbox predefined fields and values
• Eligibility sandbox API values and test responses
• Sandbox examples
• OpenAPI spec
  A JSON document, using which you can view all the allowable fields and objects for the API through a OpenAPI Swagger preview. All of our API collections provide this specification as an easy download.

Production environment

https://apigw.changehealthcare.com

📘

NOTE

Some API collections also support a separate API for Raw-X12 EDI transactions. You can send your API request and receive your responses in X12 format instead of JSON. We provide the Postman collection for testing and investigation API usage; it is not a substitute for a console used in a business context for processing eligibility requests and claims requests of various types.
