Cannot update Jira issue fields via REST API (in Python)

Amir Katz (Outseer)

I am using this code:

payload = {'update': { 'summary': [ {'set': 'new summary here'} ] } }

url = 'https://my-jira-server/resr/api/2/issue/CCB-666'

headers = {
 'Content-Type': 'application/json',
 'Accept': 'application/json',
}

requests.put(url, headers=headers, data=payload)

The call fails with error 400 with this message:

"Unexpected character ('u' (code 117)): expected a valid value (number, String, array, object, 'true', 'false' or 'null')"

I've verified that the 'u' it refers to is the start of the 'update' in the payload.

What am I doing wrong here?

Found the solution!

After re-reading requests() documentation here: https://requests.kennethreitz.org/en/master/user/quickstart/, in the section titled 'More complicated POST requests',

I changed the code to this:

requests.put(url=url, headers=headers, json=payload)

and it worked.
