How can I check the Operating Status of the API?

You can use the Healthcheck API. All of Change Healthcare's APIs offer a Healthcheck feature. It allows you to check the operating state of each API, which is the first thing you can do if something goes wrong. Use the following API endpoint to send status queries:

https://apigw.changehealthcare.com/medicalnetwork/claimstatus/v2/healthcheck

If the API engine is working correctly, you'll see the following message:

{
    "status": "OK",
    "version": "v2"
}
