Describe the Issue

When requesting a response from the mock server endpoint, I am passing the x-api-key.
My endpoint has an example saved which has status code 200 OK.

When I try to access it using header x-mock-response-name: refData, it works.
However when I try to access it using header x-mock-response-code: 200, it returns a 404 error -

{
    "error": {
        "name": "mockRequestNotFoundError",
        "message": "Double check your method and the request path and try again.",
        "header": "No matching requests"
    }
}

Steps To Reproduce

1. Create a mock-server
2. Make it private
3. Generate an API Key
4. create and endpoint in the mock server's collection
5. save an example to that endpoint named refData with response code as 200 OK
6. Access that endpoint with the following 2 headers -
   x-api-key:xxx and x-mock-response-name: refData
   It works.
7. Change one if the headers from x-mock-response-name: refData to
   x-mock-response-code: 200
8. You get the above mentioned error.

Hi @bhuvanmehra , I am sorry to see that you are not able to use mock servers. I tried out all the steps to reproduce this error and it seems to be working fine for me. I have a hunch there might be some other matching criteria that's getting applied to your mock request that's not evident here. Can you share the collection json with me so I can determine what exactly is causing the error?

Meanwhile here's some additional information that might help you in getting a successful mock response via additional headers: https://learning.postman.com/docs/designing-and-developing-your-api/mocking-data/mock-with-api/. Let me know if this works for you.
