Test the Apollo API

There are many options for testing the API. For this article, Apollo is going to use Postman, but the same information can be applied to your preferred testing methods.

To get started, create a new request in Postman. Select the GET method, then copy and paste in the URL field.

New Request

Click the Authorization tab, then select No Auth from the Auth Type drop-down.


Click the Headers tab, then add the following keys and values:

Key Value
Content-Type application/json
Cache-Control no-cache
X-Api-Key Enter your Apollo API key

Keys and Values

Click Send. This sends a request to the Apollo server to log into the API. If your setup is correct, you will receive the following JSON response:

"healthy": true, 
“is_logged_in”: true

If both values in the response are true, you are ready to use the API.

False Response

If either object has a value of False, check your request details again. Delete any erroneous spaces or returns after your API key. Once you are sure your request is formatted appropriately, click Send to try again.
