Fixing a CORS error

You are seeing one of the following errors while sending requests

  • CORS Error: The request is blocked because of the Cross-Origin Resource Sharing (CORS) policy.
  • Error: Browser does not support cross-origin requests.

How to unblock yourself

Install the Postman Desktop Agent for your OS on our download page.

Note: The CORS error generally happens due to browser limitations regarding resources shared between different internet domains. Please refer to this blog post for more information about CORS and how the Postman Desktop Agent works.
