Integration modes

The TaskMode parameter controls how CloudFlow handles the API response. The following table describes the available modes.

For other modes and their differences, see the "Integration modes" section of Integration overview.

Step 1: Create a workflow

1. Log on to the CloudFlow console. In the top navigation bar, select a region.

   1. Select Use Blank Canvas.

   2. In the Workflow mode section, select a workflow mode.

   3. Set the Workflow Name and Workflow description.

   4. Click Create.

Step 2: Configure the execution role and timeout

On the Workflow Studio graphical interface:

2. Click the Configure Workflow tab and set the Execution Role.

Step 3: Add an API action

Add an API action using the visual editor or the YAML editor.

Option A: Visual editor

      VpcId: vpc-bp11y195luy47h8****
      VSwitchId: vsw-bp1wb297ekw7xyh****
    End: true

The following table describes the key parameters.
