## You are experiencing the following issue

After sending a request, the response results in the error *401 Unauthorized*

## What to expect

* 401 Unauthorized response status codes indicate server-related errors.
* A 401 Unauthorized Error is an HTTP status code that indicates the server received an unauthenticated request due to missing or invalid credentials for the requested resource.

## Unblock yourself

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](/docs/sending-requests/authorization/authorization-types) 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](/docs/sending-requests/response-data/troubleshooting-api-requests/#opening-the-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.
