Use the WebHook activity to call an endpoint and wait for it to complete

A webhook activity can control the execution of pipelines through custom code. With the webhook activity, code can call an endpoint and pass it a callback URL. The pipeline run waits for the callback invocation before it proceeds to the next activity.

Prerequisites

To get started, you must complete the following prerequisites:

Add a WebHook activity to a pipeline with UI

To use a WebHook activity in a pipeline, complete the following steps:

Creating the activity

  1. Create a new pipeline in your workspace.

  2. Search for WebHook in the pipeline Activities pane, and select it to add it to the pipeline canvas.

    Note

    Unless your screen has a very high resolution, you likely need to expand the list of activities from the toolbar using the elipsis ... button to find the WebHook activity.

  3. Select the new WebHook activity on the canvas if it isn't already selected.

Refer to the General settings guidance to configure the General settings tab.

Web activity settings

  1. Select the Settings tab, select an existing connection from the Connection dropdown, or create a new connection, and specify its configuration details.

  2. When you create a new connection, you see the connection creation dialog where you can provide the base URL and credentials to connect.

  3. After choosing or creating your connection, complete the remaining required fields, add any required headers, or set any advanced settings. The WebHook activity only supports the POST method.

  4. Use the output from the activity as the input to any other activity, and reference the output anywhere dynamic content is supported in the destination activity.

Save and run or schedule the pipeline

Typically, you use the output of the WebHook activity with other activities, but once configured, it can be run directly without other activities, too. If you're running it to invoke a REST API that performs some action and you don't require any output from the activity, your pipeline might contain only the Web activity, too. To run the activity, switch to the Home tab at the top of the pipeline editor, and select the save button to save your pipeline. Select Run to run it directly, or Schedule to schedule it. You can also view the run history here or configure other settings.
