Your Sandbox Credentials and Environment

Bearer Token



The lifespan of a Bearer token is one hour (3600 seconds) for both sandbox and production environments.

We recommend automating transactions to use the tokens generated over the token lifespan. Obtaining tokens for each transaction is less efficient and does not improve the security criteria for any transactions.

  1. After generating the bearer token, continue trying our Medical Network APIs.
  2. In the left navigation, if you are sending in the JSON format , click POST Check Eligibility and if you are sending in the X12 format, click POST Check Eligibility X12.
  3. Click on the Body Params to view the Eligibility request.
  4. Click Send to view the response.

Please use the sandbox predefined fields and values to try our Medical Network APIs.
