attributes property
Endpoint configuration attributes that can be used to control different aspects of the message delivery.
The only currently supported attribute is x-goog-version
, which you can
use to change the format of the pushed message. This attribute indicates
the version of the data expected by the endpoint. This controls the shape
of the pushed message (i.e., its fields and metadata). If not present
during the CreateSubscription
call, it will default to the version of
the Pub/Sub API used to make such call. If not present in 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 only supported values for the
x-goog-version
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. For example: attributes { "x-goog-version": "v1" }
Optional.
