JIRA REST API: Create Issues via API, required fields

Question

Hi, can somebody help me to find out how can I get a list of all required fields for creating an issue?

There's https://example.atlassian.net/rest/api/2/field API that returns a list of fields, but we can not see there what fields are required for a specific project, for example for a project, the "components" are required, for another - no?

Is there a possibility to check the required fields to create an issue?

Thank you!

Hey there, I just wanted to share what helped for me just in case it could help anyone else:

To determine the required fields needed to create my jira issue from the POST method, I did the following:

First, I added this import to help with debugging: (in python)

import logging

logging.basicConfig(level=logging.DEBUG)

Then, upon running my code to create the jira issue, it would let me know in the Response text what fields I am missing/what fields I am adding that is in the wrong format:Example:DEBUG:atlassian.rest_client:HTTP: Response text -> {"errorMessages":[],"errors":{"issuetype":"Specify an issue type"}}

In this case it said I am missing an issue type, which after cross comparing to a manually created issue, I realised it was the field 'issuetype'. Through this, I iteratively fixed the issues one at a time until I had all of the relevant fields for the issue creation. This is just one way of doing it and probably not too efficient but it's what worked for me :)
