)

Arguments

topic	The name of the Cloud Pub/Sub topic or a Topic object from topics_get

When using a PubSub trigger, you can use data within your PubSub message in substitution variables within the build. The data from pubsub is available in the variable value: $(body.message.data.x) when x is a field in the pubsub message.
