REST API Authentication In Atlassian using Microsoft Entra ID (Previously known as Azure AD) as OAuth Provider

Enhance API Security for Jira REST APIs with OAuth/API Token plugin will let you authenticate any application (Jira, Confluence, Bitbucket) APIs using any third-party OAuth/OIDC provider or API Tokens. The app supports Azure AD, Keycloak, Okta, AWS Cognito, Google, Github, Slack, Gitlab, Facebook, and any custom provider.

Atlassian provides REST APIs to perform several operations such as Create Page, Delete Page, Add Comment, Create Space, etc. However, it supports only two authentication methods for REST APIs:

1. Basic Authentication

2. Using OAuth 1.0
