Azure DevOps API Skill

This skill provides comprehensive guidance for working with the Azure DevOps REST API, enabling programmatic access to all Azure DevOps Services and Azure DevOps Server resources.

Overview

Azure DevOps REST API is a RESTful web API enabling you to access and manage work items, repositories, pipelines, test plans, artifacts, and more across all Azure DevOps services.

Base URL: https://dev.azure.com/{organization}/{project}/_apis/{area}/{resource}?api-version={version}

  • Organization: Your Azure DevOps organization name
  • Project: Project name (optional for org-level resources)
  • API Version: Required on all requests (e.g., 7.1, 7.0, 6.0)
  • Authentication: Personal Access Tokens (PAT), OAuth 2.0, or Azure AD

Quick Start

Authentication Requirements

Azure DevOps supports multiple authentication methods:

  1. Personal Access Token (PAT) - Most common for scripts and integrations
  2. OAuth 2.0 - For web applications
  3. Azure Active Directory - For enterprise applications
  4. SSH Keys - For Git operations only

Basic PAT Authentication

GET https://dev.azure.com/{organization}/_apis/projects?api-version=7.1
Authorization: Basic {base64-encoded-PAT}

To encode PAT: base64(":{PAT}") - Note the colon before the PAT.

Common Request Pattern

GET https://dev.azure.com/{organization}/{project}/_apis/{resource}?api-version=7.1
Authorization: Basic {encoded-PAT}
Content-Type: application/json

Core Services

Azure DevOps is organized into major service areas. Each area has its own set of REST APIs:

Azure Boards - Work Item Tracking

Work Items

Common Operations

Pagination

Azure DevOps API uses continuation tokens for pagination:

Response with continuation token:

{
  "count": 100,
  "value": [...],
  "continuationToken": "MTIz"
}

Next request:

GET /{endpoint}?continuationToken=MTIz&api-version=7.1

Some endpoints use $top and $skip:

GET /{endpoint}?$top=100&$skip=100&api-version=7.1

Filtering & Querying

OData-style filters (select endpoints):

GET /{endpoint}?$filter=state eq 'Active'&api-version=7.1

Work item queries use WIQL (Work Item Query Language):

SELECT [System.Id], [System.Title], [System.State]
FROM WorkItems
WHERE [System.WorkItemType] = 'Bug'
  AND [System.State] = 'Active'
  AND [System.AssignedTo] = @Me
ORDER BY [System.ChangedDate] DESC

Batch Operations

Some Azure DevOps APIs support batch operations:

Work Items batch get:

GET /{organization}/_apis/wit/workitemsbatch?ids=1,2,3,4,5&api-version=7.1

Git items batch:

POST /{organization}/{project}/_apis/git/repositories/{repositoryId}/itemsbatch?api-version=7.1
{
  "itemDescriptors": [
    {"path": "/file1.txt", "version": "main"},
    {"path": "/file2.txt", "version": "main"}
  ]
}

JSON Patch for Updates

Work items and some other resources use JSON Patch (RFC 6902):

Operations:

  • add - Add a field or relationship
  • remove - Remove a field
  • replace - Replace field value
  • test - Test a value (for concurrency)
  • copy - Copy a value
  • move - Move a value

Example:

[
  {
    "op": "add",
    "path": "/fields/System.Title",
    "value": "New title"
  },
  {
    "op": "replace",
    "path": "/fields/System.State",
    "value": "Active"
  },
  {
    "op": "add",
    "path": "/relations/-",
    "value": {
      "rel": "System.LinkTypes.Hierarchy-Reverse",
      "url": "https://dev.azure.com/{org}/_apis/wit/workItems/123"

Error Handling

Azure DevOps API returns standard HTTP status codes:

  • 200 OK - Success
  • 201 Created - Resource created
  • 202 Accepted - Request accepted (async operation)
  • 204 No Content - Success, no content
  • 400 Bad Request - Invalid request
  • 401 Unauthorized - Authentication required
  • 403 Forbidden - Insufficient permissions
  • 404 Not Found - Resource not found
  • 409 Conflict - Conflict (e.g., version mismatch)
  • 429 Too Many Requests - Rate limit exceeded
  • 500 Internal Server Error - Server error
  • 503 Service Unavailable - Service unavailable

Error response format:

{
  "id": "request-id",
  "innerException": null,
  "message": "TF401019: The Git repository with name or identifier MyRepo does not exist or you do not have permissions for the operation you are attempting.",
  "typeName": "Microsoft.TeamFoundation.Git.Server.GitRepositoryNotFoundException",
  "typeKey": "GitRepositoryNotFoundException",
  "errorCode": 0,
  "eventId": 3000
}

Rate Limiting

Azure DevOps enforces rate limits:

  • Global limit: Varies by service (typically 200-300 requests per minute)
  • TSTUs (Team Services Time Units): Used to measure resource consumption
  • Retry-After header: Indicates when to retry after 429 error

Best practices:

  • Implement exponential backoff
  • Respect Retry-After header
  • Cache responses when appropriate
  • Use batch operations when available

Permissions & Scopes

PAT Scopes

When creating Personal Access Tokens, select appropriate scopes:

  • Agent Pools: Read & manage
  • Analytics: Read
  • Audit: Read audit log
  • Build: Read & execute
  • Code: Full, Read, or Status
  • Extensions: Read & manage
  • Graph: Read
  • Identity: Read
  • Marketplace: Acquire, manage, publish
  • Member Entitlement Management: Read & write
  • Packaging: Read, write, & manage
  • Project and Team: Read, write, & manage
  • Release: Read, write, execute, & manage
  • Secure Files: Read, create, & manage
  • Service Connections: Read, query, & manage
  • Symbols: Read
  • Task Groups: Read, create, & manage
  • Test Management: Read & write
  • Tokens: Read & manage
  • User Profile: Read & write
  • Variable Groups: Read, create, & manage
  • Work Items: Full, Read, & write

Important: Always use the least privileged scope required.

OAuth 2.0 Scopes

For OAuth applications, use scopes in the format:

  • vso.work - Work items (read)
  • vso.work_write - Work items (write)
  • vso.code - Code (read)
  • vso.code_write - Code (write)
  • vso.build - Build (read)
  • vso.build_execute - Build (execute)

Full list: https://docs.microsoft.com/azure/devops/integrate/get-started/authentication/oauth

API Versioning

Azure DevOps APIs use explicit versioning:

Versions:

  • 7.1 - Latest stable (recommended)
  • 7.0 - Stable
  • 6.0 - Stable
  • 5.1 - Older stable
  • Versions with -preview suffix (e.g., 7.1-preview.1) - Preview features

Version format:

  • api-version=7.1 - Latest patch of 7.1
  • api-version=7.1-preview.1 - Preview version 1 of 7.1

Important:

  • Always specify api-version (required on all requests)
  • Preview APIs may change or be removed
  • Use stable versions for production
  • Monitor deprecation notices

Best Practices

Performance

  1. Use batch operations when fetching multiple items
  2. Implement pagination for large result sets
  3. Use specific fields with $select where supported
  4. Cache responses when appropriate
  5. Use delta queries for incremental sync
  6. Leverage continuation tokens properly

Security

  1. Store PATs securely (use Azure Key Vault or similar)
  2. Use appropriate scopes (least privilege)
  3. Rotate PATs regularly (set expiration)
  4. Use HTTPS only
  5. Validate input to prevent injection
  6. Implement proper error handling
  7. Log security events
  8. Never commit PATs to source control

Development

  1. Use latest stable API version
  2. Handle rate limits with retry logic
  3. Implement exponential backoff
  4. Check for preview API stability before using
  5. Monitor service health
  6. Use JSON Patch for updates
  7. Validate responses
  8. Handle pagination correctly
  9. Test with various edge cases
  10. Use descriptive error messages

Integration Patterns

  1. Webhooks (Service Hooks): For event-driven integrations
  2. Polling: For batch processing (avoid excessive polling)
  3. Scheduled Jobs: For periodic sync operations
  4. Real-time sync: Using service hooks + API calls

  • Some endpoints may require preview API versions
  • Always check the official documentation for latest changes
  • API versions and endpoints may evolve over time
  • Rate limits and throttling policies apply
  • Proper authentication and permissions are required for all operations
  • Some features are only available in Azure DevOps Services, not Server
