How can I find custom field info on Jira Cloud?

[Johnny Test]

Our team has a lot of custom fields and some that are named the same. As I understand each custom field has a unique ID that is mapped to the display name, and that's why we can name fields the same because that's not their true identifier. My Question is how do we find this information, like what is the unique ID for a given field and ideally metadata about the field like what type of data it stores. 

Thanks so much!

Hi @Johnny Test 

You can find this information using the following URL (replacing "{yoursite}")

https://{yoursite}.atlassian.net/rest/api/latest/field

If you are already authenticated to your jira site you can access the URL through the broswer and then search for the custom field name.

Hope that helps! Let me know if you have any questions.

Thanks,
Jack
