Authentication with Postman

This topic covers handling Geovisualization authentication using Postman.

To authenticate with Postman we recommend you first read Getting Authentication Credentials and Using Postman.

Obtaining an Access Token

To obtain an authentication token use the sign_in endpoint which you can find in the 01. User Authentication folder of our Postman collection. If you followed Using Postman you should have your email and password already set, if not, then add them under the Body tab of the endpoint.

If you followed Using Postman you should have your app_id and app_code already set, if not, then add them under the Headers tab of the endpoint.

Click the blue Send button and you will receive a response like the below, containing a new access_token:

(The access_token above has been truncated for presentation purposes.)

Note: You will need to provide the refresh_token (line 15 in the figure above) to refresh the access token for the session as described below.

Refreshing Authentication Tokens

Access tokens are valid for 60 minutes. If you get the error message token expired, you can refresh the token by using the sign_in/refresh endpoint which you can find in the 01. User Authentication folder of our Postman collection.
