What is the correct way to identify customfield id of Sprint by rest api in Jira Software?

Question

What is the correct way of identifying the sprint custom field in JIRA by rest api? Someone can create multiple custom fields in the system with the name "Sprint". So how do I identify which is the standard custom field "Sprint" of Jira Software?

Is it identified with the help of the string "com.pyxis.greenhopper.jira:gh-sprint" found in response by the rest api: "/rest/api/2/field"?

Rename one of the fields to "Story points" or "Story Points."

Or, better, if someone has done this, remove their admin access from Jira as they really shouldn't be making mistakes like that.  It also is possible to do it by accident when upgrading or migrating though.  However a duplicate got there though, remove it.  You should not duplicate field names, especially something like Story points, for which there is no sane reason to have two fields.

What if someone has created two fields with the same name "Story Points", then how do I identify which is the correct field used for estimation?

Epic link is similar - com.pyxis.greenhopper.jira:gh-epic-link  but Story points is a standard numeric custom field
