How to get the start date for an issue

[insidr]

Hi, 

I have searched everywhere, but can't find a way through the Rest Api to get the startDate of an issue  to calculate time taken to complete the issue.

Thanks in advance

The start date is not a standard field. The value of the start will be available in the custom field. In my case, I got the start date value in the 'customfield_10015' field.

What do you mean by startDate of an issue? Do you mean the createdDate? If so, just use GET /rest/api/2/issue/{issueIdOrKey}

No, It was custom field
