-- the endpoint. This controls the shape of the pushed message (i.e., its
-- fields and metadata). The endpoint version is based on the version of
-- the Pub\/Sub API. If not present during the \`CreateSubscription\` call,
-- it will default to the version of the API used to make such call. If not
-- present during a \`ModifyPushConfig\` call, its value will not be
-- changed. \`GetSubscription\` calls will always return a valid version,
-- even if the subscription was created without this attribute. The
-- possible values for this attribute are: * \`v1beta1\`: uses the push
-- format defined in the v1beta1 Pub\/Sub API. * \`v1\` or \`v1beta2\`:
-- uses the push format defined in the v1 Pub\/Sub API.

-- | Defines an Identity and Access Management (IAM) policy. It is used to
-- specify access control policies for Cloud Platform resources. A
-- \`Policy\` consists of a list of \`bindings\`. A \`binding\` binds a
-- list of \`members\` to a \`role\`, where the members can be user
-- accounts, Google groups, Google domains, and service accounts. A
-- \`role\` is a named list of permissions defined by IAM. **JSON Example**
-- { \"bindings\": [ { \"role\": \"roles\/owner\", \"members\": [
-- \"user:mike\'example.com\", \"group:admins\'example.com\",
-- \"domain:google.com\",
-- \"serviceAccount:my-other-app\'appspot.gserviceaccount.com\" ] }, {
-- \"role\": \"roles\/viewer\", \"members\": [\"user:sean\'example.com\"] }
-- ] } **YAML Example** bindings: - members: - user:mike\'example.com -
-- group:admins\'example.com - domain:google.com -
-- serviceAccount:my-other-app\'appspot.gserviceaccount.com role:
-- roles\/owner - members: - user:sean\'example.com role: roles\/viewer For
-- a description of IAM and its features, see the [IAM developer\'s
