Python

Before trying this sample, follow the Python setup instructions in the Workflows quickstart using client libraries. For more information, see the Workflows Python API reference documentation.

# This snippet has been automatically generated and should be regarded as a
# code template only.
# It will require modifications to work:
# - It may require correct/in-range values for request initialization.
# - It may require specifying regional endpoints when creating the service
#   client as shown in:

    request = workflows_v1.UpdateWorkflowRequest(

    operation = client.update_workflow(request=request)

    print("Waiting for operation to complete...")

    response = operation.result()

    # Handle the response
    print(response)

Ruby

Before trying this sample, follow the Ruby setup instructions in the Workflows quickstart using client libraries. For more information, see the Workflows Ruby API reference documentation.

require "google/cloud/workflows/v1"

##
# Example demonstrating basic usage of
# Google::Cloud::Workflows::V1::Workflows::Client#update_workflow
#
def update_workflow
  # Create a client object. The client can be reused for multiple calls.
  client = Google::Cloud::Workflows::V1::Workflows::Client.new

  # Create a request. To set request fields, pass in keyword arguments.
  request = Google::Cloud::Workflows::V1::UpdateWorkflowRequest.new

  # Call the update_workflow method.
  result = client.update_workflow request

  # The returned object is of type Gapic::Operation. You can use this
  # object to check the status of an operation, cancel it, or wait
  # for results. Here is how to block until completion:
  result.wait_until_done! timeout: 60
  if result.response?
    p result.response
  else
    puts "Error!"
  end
end
