API Request Header

The most up-to-date URL is, https://apigw.optum.com. This URL provides overall increased performance and stability. Do not use https://apis.changehealthcare.com, this URL is an old domain and is no longer supported.

Use this header information for these eligibility operations unless otherwise noted: Eligibility, Eligibility EDI, and Eligibility Views. We use two standard HTTP headers in our API requests: Authorization and Content-Type.

The API request uses the following header format:

```javascript
		 --url https://sandbox-apigw.optum.com/medicalnetwork/eligibility/v3/ \
     --header 'Authorization: Bearer eyJraWQiOiIxIiwidHlwIjoi...' \
     --header 'accept: application/json' \
     --header 'content-type: application/json' \
     --data'
```

Content-Type header always defaults to application/json
Bearer authorization token in the Authorization header
Get an authorization token by making a request generate a Bearer token
