Okta API Access Management secures APIs through centralized control and enforcement of access policies using OAuth 2.0 and OpenID Connect standards. It enables organizations to create custom authorization servers with granular scopes and claims, define context-aware access rules based on user roles, devices, or network conditions, and integrate with API gateways for additional security layers. The solution supports both cloud-based and on-premises applications, offers detailed audit logs for compliance, and allows dynamic token validation through HTTP headers to prevent unauthorized access. It leverages Okta's Universal Directory for identity management and provides scalable administration tools for managing API clients across partners, employees, and customers.
