For detailed information and\nexamples, see the Cloud Run\n[Authenticate requests](/run/docs/authenticating/overview) guides. The topics\ncovered in the Cloud Run guides also apply to functions created using the\n[Cloud Functions v2 API](/functions/docs/apis), since v2 functions also\nuse the\n[Cloud Run Invoker role](/run/docs/reference/iam/roles#run.invoker)\n(`roles/run.invoker`).\n\nTo invoke an authenticated function, the underlying\n**principal** must meet the following requirements:\n\n- Have permission to invoke the function.\n- Provide an ID token when it invokes the function.\n\nCloud Run functions supports two different kinds of identities, which are also\ncalled **principals**:\n\n- Service accounts: These are special accounts that serve as the identity of a non-person, like a function or an application or a VM. They give you a way to authenticate these non-persons.\n- User accounts: These accounts represent people, either as individual Google Account holders or as part of a Google-controlled entity like a Google Group.\n\nSee the [IAM overview](/iam/docs/overview) to learn more about\nbasic IAM concepts.\n\nTo invoke an authenticated function, the principal must have the invoker\nIAM **permission**:\n\n- `run.routes.invoke`. This is usually through the [Cloud Run Invoker role](/run/docs/reference/iam/roles#run.invoker). This permission must be assigned on the Cloud Run service resource.\n\nTo grant these permissions, follow the steps in the\nCloud Run\n[Authenticating service-to-service](/run/docs/authenticating/service-to-service#set-up-sa) guide.\n\nFor permission to create, update, or perform other administrative actions on a\nfunction, the principal must have an appropriate **role** . Roles include permissions that define the actions that the principal is allowed to do. See\n[Using IAM to Authorize Access](/functions/docs/securing/managing-access-iam)\nfor more information.\n\nEvent-driven functions can only be invoked by the event source that they're\nsubscribed to. HTTP functions, however, can be invoked by different identity\ntypes originating from different places, such as by a developer testing the\nfunction or by another service using the function. Identities must provide an ID\ntoken for authentication. The account in use must also have the appropriate\npermissions."]]
