jira cloud api save value for multi line text field

[hadesunseenn]

working with jira cloud api v3. When creating an issue I am able to save data for single line text field but not able to save data for multi line text field.  Here is how the data looks for single line. Its just key and value, it does not work for multi line though

---

"customfield_10014": "IN-14"

can you please let me know which params we need to save data for multi line !

api gives this error

"customfield_10029":"Operation value must be an Atlassian Document (see the Atlassian Document Format)"}

Hi @hadesunseenn 

You may want to look at this defect for a work-around using the REST API v2:

Kind regards,

thanks @Bill Sheboy for quick response

I have already implemented a lot of apis using v3. Dont want to redo all just for one field. 

Can you please tell me how do i need to format the request ?

Please see this post for two different examples of how to do this: either escaping the newline character or using the ADF paragraph node syntax.
