API request response error

[Ozan_Ketenci]

Hi,

I am trying to do some test with API but couldn't get any response from cloud. I am using Postman to send the request. Here is the steps that I took so far:

1. Using this URL to post my request: https://mydomain.atlassian.net/rest/api/2/issue/

2. Using API Key auth. to login. I used my login email as key and API token as value.

3. I created a basic "create issue" body to post:

4. And the response is:

I have already eliminated 2nd, 3rd and 4th possible reason. So, can you please help me to find what I am doing wrong?

Thanks.
