+The @api_client_authorizations@ resource stores the API tokens that have been issued to permit access the API server.
+
+An ApiClientAuthorization is *not* a generic Arvados resource. The full list of properties that belong to an ApiClientAuthorization is:
+
+table(table table-bordered table-condensed).
+|_. Attribute|_. Type|_. Description|_. Example|
+|uuid|string|An identifier used to refer to the token without exposing the actual token.||
+|api_token|string|The actual token string that is expected in the Authorization header.||
+|api_client_id|integer|-||
+|user_id|integer|-||
+|created_by_ip_address|string|-||
+|last_used_by_ip_address|string|The network address of the most recent client using this token.||
+|last_used_at|datetime|Timestamp of the most recent request using this token.||
+|expires_at|datetime|Time at which the token is no longer valid. May be set to a time in the past in order to immediately expire a token.||
+|owner_uuid|string|The user associated with the token. All operations using this token are checked against the permissions of this user.||
+|scopes|array|A list of resources this token is allowed to access. A scope of ["all"] allows all resources. See below.||
+
+h3(#scope). Scopes
+
+Scopes can restrict a token so it may only access certain resources. This is in addition to normal permission checks for the user associated with the token.
+
+Each entry in scopes consists of a @request_method@ and @request_path@, where the @request_method@ is a HTTP method (one of @GET@, @POST@, @PUT@ or @DELETE@) and @request_path@ is the request URI. A given request is permitted if it matches a scopes exactly, or the scope ends with @/@ and the request string is a prefix of the scope.
+
+As a special case, a scope of ["all"] allows all resources.
+
+h4. Examples
+
+A scope of @GET /arvados/v1/collections@ permits listing collections.
+
+* Requests with different methods, such as creating a new collection using @POST /arvados/v1/collections@, will be rejected.
+* Requests to access other resources, such as @GET /arvados/v1/groups@, will be rejected.
+* Be aware that requests for specific records, such as @GET /arvados/v1/collections/962eh-4zz18-xi32mpz2621o8km@ will also be rejected. This is because the scope @GET /arvados/v1/collections@ does not end in @/@
+
+A scope of @GET /arvados/v1/collections/@ (with @/@ suffix) will permit access to individual collections.
+
+* The request @GET /arvados/v1/collections/962eh-4zz18-xi32mpz2621o8km@ will succeed
+* Be aware that requests for listing @GET /arvados/v1/collections@ (no @/@ suffix) will be rejected, because it is not an exact match with @GET /arvados/v1/collections/@
+
+To allow both listing objects and requesting individual objects, include both in the scope: @["GET /arvados/v1/collections", "GET /arvados/v1/collections/"]@
+
+A narrow scope such as @GET /arvados/v1/collections/962eh-4zz18-xi32mpz2621o8km@ will disallow listing objects as well as disallow requesting any object other than those in the scope.
