To authenticate, you'll need to request an access token. Run the following command, substituting your "client_id" and "client_secret":

  curl \
    -H "Content-type: application/json" \
    -d '{"grant_type": "client_credentials", "client_id": "19c1514d-...", "client_secret": "a6af3083..."}' \
    https://auth.sensourceinc.com/oauth/token

You will get a response with the access token in it:

  {
    "access_token":"7a7f1d1256f67e531359f00e6feea254a1d605c5947cd1d3610a01249ccb5acc",
    "refresh_token":"718f6ff90c644866f564df9090dc2f905112c74959a5caf79587c78fd5c04a55",
    "expires_in":3600,
    "token_type":"Bearer"
  }

Copy the "access_token" value ("7a7f1d..." in the example). Click the "Authorize" button in the API docs. Then enter in the same thing you'd enter in the "Authorization" header for an API request: the word "Bearer", then a space, then the access_token value:

You should now be able to make the API calls
