// API Overview
//
//
// Manages Identity and Access Management (IAM) policies.
//
// Any implementation of an API that offers access control features
// implements the google.iam.v1.IAMPolicy interface.
//
// ## Data model
//
// Access control is applied when a principal (user or service account), takes
// some action on a resource exposed by a service. Resources, identified by
// URI-like names, are the unit of access control specification. Service
// implementations can choose the granularity of access control and the
// supported permissions for their resources.
// For example one database service may allow access control to be
// specified only at the Table level, whereas another might allow access control
// to also be specified at the Column level.
//
// ## Policy Structure
//
// See google.iam.v1.Policy
//
// This is intentionally not a CRUD style API because access control policies
// are created and deleted implicitly with the resources to which they are
// attached.
service IAMPolicy {
  option (google.api.default_host) = "iam-meta-api.googleapis.com";

  // Sets the access control policy on the specified resource. Replaces any
  // existing policy.
  //
  // Can return `NOT_FOUND`, `INVALID_ARGUMENT`, and `PERMISSION_DENIED` errors.

      post: "/v1/{resource=**}:setIamPolicy"

  // Returns an empty policy if the resource exists and does not have a policy
  // set.

      post: "/v1/{resource=**}:getIamPolicy"

    };
  }

  // Returns permissions that a caller has on the specified resource.
  // If the resource does not exist, this will return an empty set of
  // permissions, not a `NOT_FOUND` error.
  //
  // Note: This operation is designed to be used for building permission-aware
  // UIs and command-line tools, not for authorization checking. This operation
  // may "fail open" without warning.
