Jira

Jira REST API provides comprehensive project management and issue tracking capabilities with OAuth 2.0, API tokens, and Basic Auth authentication methods.

Version 3 supports Atlassian Document Format (ADF) with approximately 300 endpoints covering issues, projects, workflows, boards, sprints, users, permissions, and webhooks.

Authentication varies by deployment: OAuth 2.0 and API tokens for Cloud, OAuth 1.0a and Basic Auth for Server/Data Center. JWT-based authentication for Atlassian Connect apps with granular scopes. Resource expansion reduces payload sizes.

Rate limiting: 600 requests per 60 seconds. JSON format with standard HTTP methods. Comprehensive webhook support for real-time event notifications.

Ideal for development workflow automation, custom reporting, agile board management, and integrations with CI/CD pipelines requiring robust issue tracking and project management capabilities across cloud and self-hosted deployments.
