How to get id or key for Issue custom field Epic Name using jira REST api /rest/api/3/field

[Jeel]

using REST Api  /rest/api/3/field I'm unable to find custom field details Epic Name in response list

I have try with access_token (using OAuth 2.0) with api.atllasian.com/ex/jira endpoint got the same response with missing detail about Epic Name

-> I'm creating Epic and its child issue with REST Api although i got the id by check manually from project settings but i need a this info dynamically as this might change one instance to other

Hello @Jeel 

Welcome to the Atlassian community.

The native Epic Name field is in the process of being deprecated. You will no longer see it in Epic type issues. Jira no longer requires that it be filled in for Epic type issues.

You should be able to create your Epics without referencing that field.

If you are having a problem creating the Epics via API, please tell us the details of that problem.

Thanks for the clarification.
