Make sure that the URL is typed correctly.

  • Check the API documentation for the service you’re accessing and confirm you’ve chosen the right authorization type in Postman.

  • Visit the service provider’s page and look for a sign-in link. Enter your credentials and then try the page again.

  • Make sure you have entered the right API Key and credentials when authorizing the request.

  • Reach out to the service provider of the endpoint you are trying to call.

  • Note: To debug the issue further, open the Postman console and view the details of your requests. This allows you to see the details of the request sent, including all underlying request headers, variable values, and redirects.
