Hello kulak-daria**,**

The “405 Method Not Allowed” error occurs when the server is configured in a way that does not allow you to perform a specific action for a particular endpoint (URL). It's an HTTP response status code that indicates that the request method is known by the server but is not supported by the target resource (your request URL).

There are multiple causes for this error, but most commonly, this is caused by the server (endpoint URL) configuration.

1. Firstly, You want to confirm which methods are supported for each endpoint and ensure that the POST method is configured. Ensure that your baseURL variable associated with your POST method is point to https://petstore3.swagger.io/api/v3
   (as highlighted in my screenshot below, as I was unable to reproduce this issue)

2. Secondly, you want to confirm the then request URL is written correctly for the POST request (confirm it has no trailing spaces for example).

3. Lastly, test if your POST request succeeds outside Postman; Send a request using cURL in your terminal. To do this, copy the cURL code generated by your request, paste it into your terminal, and send the request.

I have also referenced a discussion about this response in our Community: https://community.postman.com/t/405-method-not-allowed/16743/3 which has some additional troubleshooting steps you may try.

I hope that this information is helpful, and I have included an export of my working collection based on Swagger PetStore documentation - should you wish to test the POST method to "Add a new pet to the store"
