As an organization administrator, you can register trusted applications and specify which domains may access CDF APIs. When a browser application calls CDF, the request originates from a specific domain. Registration lets you control which web applications are allowed to make those browser-based requests and blocks unauthorized origins. Registration lets CDF recognize trusted applications and configure domain-based validation and Cross-Origin Resource Sharing (CORS) policy. It reduces the attack surface for browser-based access by letting you define trusted origins from which requests to CDF can be made. Application registration does not replace authentication, authorization, or other security controls.
Registering in CDF is separate from registering in your identity provider (IdP). For web applications, complete both steps: register in your IdP for authentication (Microsoft Entra ID or Amazon Cognito), then register in CDF to configure allowed origins.

​
Prerequisites

  • You must be an organization administrator.
  • The application must already be registered in your organization’s IdP if it uses interactive or service principal authentication.
Domains for CDF applications such as Maintain, InField, and Flows are registered in your organization by default.For Flows apps, we recommend registering each app individually for clearer ownership, security, and future compatibility. Application registrations validate trusted domains, not individual application identities, so if multiple applications share a domain, a request from an unregistered application may still be accepted if another application on that domain is already registered.
