Method: googleapis.workflowexecutions.v1.projects.locations.workflows.triggerPubsubExecution

Triggers a new execution using the latest revision of the given workflow by a Pub/Sub push notification.

This method waitsโ€”the workflow execution is pausedโ€”until the operation is complete, fails, or times out. The default timeout value is 1800 seconds (30 minutes) and can be changed to a maximum value of 31536000 seconds (one year) for long-running operations using the connector_params field.

The connector uses polling to monitor the long-running operation, which might generate additional billable steps. The polling policy for the long-running operation can be configured. For example, if you set skip_polling to True, the connector invocation call is non-blocking if the initial request succeeds; otherwise, retries might occur.

For more information about connector-specific parameters (connector_params), see Invoke a connector call.

For more information about retries and long-running operations, see Understand connectors.
