how to update the parent field of an issue with API

[N.O]

Hi, with the new changes to the parent field. I do not see any documentation to update (also remove) the parent linked to an issue. Is this possible via the API if not how do we do this as I am getting unexpected results from the API? is /rest/api/latest/issue the right endpoint? I have tried setting this field's value to null but that doesn't work

Hello @N_O 

The Edit Issue endpoint is working just fine for me.

To change a particular Story's parent Epic, I send the following request:

PUT https://{Instance}.atlassian.net/rest/api/3/issue/KEY-123

with the following request body:

{
 "fields": {
  "parent": {
   "key": "KEY-234"
   }
  }
}

then that Story gets a different parent Epic.

If I set the parent field to null:

{
 "fields": {
  "parent": {
   "key": null
   }
  }
}

then that Story has no Epic.

Can I update/add?

[DaYuan Tan]

I tried { "update": { "parent": [ { "set": { "key": "parent_issue_key" } } ] } }

or

{ "update": { "parent": [ { "add": { "key": "parent_issue_key" } } ] } }

they both don't work.

I am doing it in Microsoft Power Automate calling Rest API Edit issue V2.

Hello @DaYuan Tan 

Can I update/add?

No. Updating / adding is for other field types that can accept multiple actions / values via multiple sets or adds inside an array[ ] in the JSON body.

For the parent field, it can accept only a single value, so you need to declare the value for the key, exactly as I've shown in my example.

Hi @Sunny Ape I am facing a similar issue so we have a job for creating JIRA tickets earlier it was linked to epic id now I would like to link it with parent id

Here is the previous request

req_body["fields"]['customfield_10014'] = env_jira_config.get('epic_id')

this is the error message
"errorMessages": [], "errors": { "customfield_10014": "Field 'customfield_10014' cannot be set. It is not on the appropriate screen, or unknown." } }

Updated the request like these

1. req_body["fields"]['customfield_10017'] = env_jira_config.get('epic_id')

2. req_body['fields']['parent']['key'] = env_jira_config.get('epic_id')

3. req_body['fields']['960298'] = env_jira_config.get('epic_id') 

4.  req_body['960298'] = env_jira_config.get('epic_id')    

in case of 1,3,4 the tickets are getting created but not getting linked to parent id
