Get Issue API

[Nishant Sharma]

I am going through Jira rest API reference Doc and looking for get issue API over here https://developer.atlassian.com/cloud/jira/platform/rest/v2/api-group-issues/#api-rest-api-2-issue-issueidorkey-get

For this API, in response, we have fields object. Can someone please let me know how we can come to know what all fields this field object will contain?

Is there any API for it? as we do have to get metadata API for creating issues and edit issue.

This object contains the standard fields, relations, and the custom fields:
Descriptions
Subtasks
Project
Comments
Worklogs
IssueLinks

Also you can add the query param ?expand=names on the end of url to have the names of the custom fields

Thanks for sharing that. I have a question on top of it.

1. Are these fields are gonna remain the same across all issues in Jira?

2. If these fields gonna change on basis of Issue Id then How we can determine which issue will what all fields. Is there any API call for this?
