I want to update "Actual End" field value which has id "customfield_10009" How I can do that?

[Deleted user]

I have used

"https://developer.atlassian.com/cloud/jira/platform/rest/v3/api-group-issues/#api-rest-api-3-issue-issueidorkey-put" 

But got an error with status code of 415 which means my payload format is in unsupported format.

I am using 

payload = {"fields": {

"customfield_10009": "2022-07-28T19:30"}}

Where am I going wrong?

Hi @[deleted] ,

Did you pass the 'Content-Type': 'application/json' header?
