What will you learn?
In this tutorial, you will learn how to efficiently retrieve Azure DevOps work-items using Python scripts. By leveraging the Azure DevOps REST API and Python libraries like requests, you will acquire work-item IDs and detailed data effortlessly.
Introduction to the Problem and Solution
When it comes to programmatically retrieving Azure DevOps work-items, interacting with the Azure DevOps REST API through Python scripts is essential. Initially, we retrieve work-item IDs by employing specific queries or filters. Subsequently, we utilize these IDs to make further API calls for obtaining comprehensive information about each individual work-item.
The solution involves utilizing Python’s requests library for handling HTTP requests and processing JSON responses from the Azure DevOps API. By structuring appropriate API calls in accordance with Azure DevOps documentation, we can effectively gather both basic ID information and detailed data pertaining to each work-item.
Code
# Import necessary libraries
import requests
# Set up variables for authentication and URL
personal_access_token = 'YOUR_PERSONAL_ACCESS_TOKEN'
organization_url = 'https://dev.azure.com/YOUR_ORGANIZATION_NAME'
project_name = 'YOUR_PROJECT_NAME'
# Get list of work item IDs
def get_work_item_ids():
url = f"{organization_url}/{project_name}/_apis/wit/workitems?api-version=6.0"
headers = {
"Authorization": f"Basic {personal_access_token}"
}
response = requests.get(url, headers=headers)
if response.status_code == 200:
return [item['id'] for item in response.json()['value']]
else:
return []
work_item_ids = get_work_item_ids()
print(work_item_ids)
# Get details of each work item based on its ID
def get_work_item_details(work_item_id):
url = f"{organization_url}/{project_name}/_apis/wit/workitems/{work_item_id}?api-version=6.0"
headers = {
"Authorization": f"Basic {personal_access_token}"
}
response = requests.get(url, headers=headers)
if response.status_code == 200:
return response.json()
for id in work_item_ids:
print(get_work_item_details(id))

Explanation
To retrieve Azure DevOps work-items using Python scripts, follow these steps:
- Import Libraries: Import the necessary library requests for making HTTP calls.
- Set Up Variables: Define variables such as personal access token, organization URL, and project name.
- Get Work Item IDs: Execute an authenticated GET request to fetch a list of work item IDs from Azure DevOps.
- Retrieve Work Item Details: Fetch detailed information about each specific work item by making another authenticated GET request based on the obtained IDs.
This approach facilitates automating the retrieval process of crucial data associated with various tasks or issues tracked within an organization’s projects on Azure DevOps.
You can generate a PAT by logging into your Azure DevOps account > User Settings > Personal Access Tokens > New Token creation.
Can I customize the fields returned when fetching details of a specific work item?
Yes, you can specify additional parameters in your API call URL according to desired fields as per Microsoft’s documentation guidelines.
Is it possible to filter or query specific types of work items during retrieval?
Absolutely! You can incorporate OData queries in your initial request URL when fetching IDs or details based on specified criteria.
What happens if my PAT is compromised or needs regeneration?
It is vital to promptly invalidate any compromised tokens and create new ones following secure practices within your account settings.
How do I handle pagination if there are numerous results while retrieving data?
Azure DevOps APIs often implement pagination mechanisms where you need to manage multiple result pages through iteration until all relevant data is successfully retrieved.
Can I schedule automated runs for these scripts at regular intervals?
Yes, you may integrate this functionality with scheduling tools like Cron jobs or Windows Task Scheduler as part of automation workflows tailored to your system requirements.
Conclusion
By exploring this tutorial, you have gained insights into using Python scripts along with REST APIs from AzureDevops via the Requests library. This enables seamless access and manipulation of real-time Data Ingestion/Extraction directly from applications running Python code snippets without requiring manual intervention during execution.
