Can you help me with setting assignee field in the web API. I do not know how exactly to fetch the names from the JIRA website for the assignee. i want to fetch those names from JIRA and then parse it on the web tool which talks to JIRA. It can fetch the version and the projects but not the list of the names of the assignee. I have tried the above solutions but somehow it doesnt work

Also, in this case, since the payload could be big, I recommend saving it in a ".json" file and your bash script can be like this:

#!/bin/bash

jira_user="ID"
jira_pw="PASS!"
jira_server="jira.test.com"

curl -D- -u "$jira_user":"$jira_pw" -X POST -H "Content-Type: application/json" https://$jira_server/rest/api/2/issue -d @payload.json

The "@payload.json" is referencing the json file with the actual payload, this is good because it also avoids the single quote issue that you were having.

Kind regards,
