Using Postman


Postman is a powerful HTTP client tool used for API testing in a user-friendly interface which displays requests and responses in structured formats.

Our Developer Portal provides you with an easy-to-use download option to begin testing our APIs in the Postman tool. 

Refer to the Postman website for tutorials and additional information

How To Test With Postman


  1. Create an app via the Developer Console
  2. Download and install Postman
  3. In an API Reference page, find an API you would like to test and select the Try in Postman button. This sets up the Postman UI and downloads the collection.
  4. Configure the Postman Authorization header (see details below)
  5. Configure an environment that defines variables used in endpoints. An environment template is provided for you in the collection and accessed via Manage Environments in Postman settings. Define these variables:

Preview Environment{practiceid}

Production Environment{practiceid}

athenahealth provides a default access to practiceid 195900

Note: ContextId and PracticeId are used interchangeably at athenahealth, both refer the same.

Configuring the Postman Authorization header

Information in this section provides configuration details for the OAuth authorization header, which is supplied with each request to the athena API. Based on the version of OAuth your app implements, configure either an OAuth 2.0 header . To help you determine the version of OAuth your app uses click here.

OAuth 2.0

Before submitting a request from the collection, Postman must generate an OAuth 2.0 access token based on OAuth 2.0 keys from your app’s dashboard on

  1. Sign-on to your developer account.
  2. Find and open the app you want to use.
  3. Navigate to the Credentials tab on your app’s dashboard. You use the Preview Environment keys for this configuration.

Now, from the Authorization tab on the Postman UI, for Type select OAuth 2.0 and click Get New Access Token. You need the following information when configuring this dialog:

Postman Authorization Field Information from your developer account
Token Name A user defined name for this token. It appears in the Postman Existing Tokens list to use in Send requests.
Grant Type This must be set to client_credentials (for 2-legged applications).


Access Token URL


Client ID and Client Secret Obtain these values from the Credentials tab on the app profile on the developer site. Make sure you get them development keys section on this tab.
Scope Specify: 

Make calls

Once you configure Postman authorization header, requests in the Postman collections here will access your information in Sandbox environment.

For each request, refresh the authorization header:

  1. Oauth 2.0: For OAuth 2.0 headers, select the desired token from the Available Tokens list and click Get New Access Token.

  2. Select the desired endpoint from the collection.

  3. Click Send to issue the API request. Response payload is returned in the Body tab.



Note: Use this tool only for testing and prototyping your API requests.

Using the collections in a production environment

To use the collections in a production environment you need the following:

  • Access to your production keys
  • Your production keys will not authorize a practice in preview environment.
  • Set { {baseURL} } to either preview or production environments baseURL as needed.
