Azure API Management with OAuth 2.0
Azure API Management with OAuth 2.0 Enabling OAuth2 in Azure API Management (APIM) ensures that all external consumers authenticate using a secure, industry-standard token-based model, regardless of how the backend systems (e.g., website, mobile apps, SaaS APIs) handle authentication. This creates a centralized security layer that abstracts backend differences, enforces consistent access control, supports fine-grained authorization (via scopes/claims), and provides detailed auditing and monitoring for compliance. In short, it improves security, governance, and partner onboarding while simplifying backend integration. In an OAuth2-enabled Azure API Management (APIM) setup, a client app first requests an access token from an Identity Provider (such as Azure AD), which validates the credentials and issues an access token (and possibly a refresh token). The client then sends its API request to APIM, including the token in the authorization header. APIM validates the token by ch...
