Jira has a Text Field (read only) in the custom field. This KB explains ways how you can modify and update this custom field. 


Jira 7 and 8


You can either update the Text field (read only) via REST API or import from Mantis. Maximum 255 characters. 

For Jira version before 8.4, you can use import from Mantis.

Starting from Jira 8.4, Jira no longer supports built-in importers that are dedicated to specific applications, including Mantis. You can still import data to Jira in CSV or JSON format.


You can use the REST API like the following to update this field. In this example, the REST API will update custom field 10201 which is the read-only text field in issue TEST-1 to "hello world". 

curl -w '%{http_code}' -u admin:admin_password  -H "Content-Type: application/json" -X PUT http://JIRA_URL/rest/api/2/issue/TEST-1  --data '{ "fields": {"customfield_10201": "hello world"} }'
