Updating Jira Cloud Field with Python

What will you learn?

In this comprehensive guide, you will delve into updating a text field in Jira Cloud using Python. You’ll gain a deep understanding of how to programmatically modify your Jira issues step by step.

Introduction to the Problem and Solution

When working with Jira Cloud, there comes a time when automating the process of updating issue fields becomes essential. This automation could be part of a larger task, such as altering tickets based on external events or data sources. However, tackling this challenge might seem daunting if you lack familiarity with the Jira Cloud API and its integration with Python.

But worry not! This tutorial has got you covered. We will walk through leveraging Python alongside the powerful requests library to update a text editable field within a Jira Cloud issue. From setting up your environment and installing necessary packages to crafting the script that executes the update, we will cover it all.


import requests
from requests.auth import HTTPBasicAuth

# Your Jira credentials and issue details
username = 'your_jira_email'
password = 'your_jira_api_token'
jira_domain = 'https://yourdomain.atlassian.net'
issue_key = 'ISSUE-123'
field_to_update = 'customfield_10000'  # Example custom field ID
new_value = "Updated value"

# Endpoint URL for updating an issue in Jira Cloud
url = f"{jira_domain}/rest/api/2/issue/{issue_key}"

# Headers and payload for the request 
headers = {
   "Accept": "application/json",
   "Content-Type": "application/json"
payload = {
    "fields": {
        field_to_update: new_value

# Performing the request 
response = requests.put(
    auth=HTTPBasicAuth(username, password),

print("Status Code:", response.status_code)
if response.status_code == 204:
    print("Successfully updated.")
    print("Failed to update:", response.json())

In this solution:

  • Authentication: Utilizing HTTPBasicAuth from requests.auth for basic authentication using your email as username and an API token as password.
  • Headers: Essential headers include accepting JSON responses and specifying content type as JSON.
  • Payload: The payload is structured where “fields” contain key-value pairs representing field IDs (or keys) and their values intended for update.
  • Making Request: A PUT request is initiated using requests.put(), incorporating our constructed URL comprising domain name and issue key, appropriate headers for content-type, authentication setup, and our payload containing data for modification.
  • Response Handling: Post sending our PUT request, we verify if its status code returned is 204 denoting success without any body content.

This approach aligns with RESTful principles of web services facilitating resource manipulation (in this case – issues in JIRA) via HTTP methods accurately reflecting actions like reading (GET), creating (POST), updating (PUT/PATCH), or deleting (DELETE).

  1. How do I find my API token?

  2. You can generate an API token by navigating to Atlassian Account settings -> Security -> API Token -> Create and manage API tokens.

  3. Can I update multiple fields at once?

  4. Yes! Add more key-value pairs inside “fields” dictionary in your payload.

  5. What if I encounter a ‘401 Unauthorized’ error?

  6. A 401 error suggests incorrect authentication details. Double-check your email/API token combination.

  7. Is there rate limiting on JIRA’s REST API?

  8. Atlassian imposes rate limits; refer to their official documentation for specific limits which are generally sufficient for most automation tasks.

  9. How can I find out available fields or their IDs?

  10. Utilize /rest/api/2/field GET endpoint on your instance – lists all fields including custom ones showing their IDs/names/types etc., aiding in constructing payloads.

  11. Can this method work for other types of fields like dropdowns or dates?

  12. Absolutely! The principle remains same; some field types may require specific formats/values structured accordingly within payloads.

  13. Do I need special permissions in my project/team/account ?

  14. Typically yes; permission depends on roles/rights assigned within projects/accounts respectively allowing creation/editing issues accordingly.


Enhancing a text editable field in a JIRA cloud issue via Python offers substantial flexibility especially when integrated into broader automation scripts/environments. By combining simple yet potent libraries like requests, interacting with APIs becomes accessible enabling vast possibilities enhancing workflows/processes efficiently across teams/projects ensuring seamless operations day-to-day activities.
