Add and configure Send Web Request—Workflow Manager Server

License:

This functionality requires a license for the ArcGIS Workflow Manager Server Advanced role.

The Send Web Request step allows you to send requests to REST endpoints to get data or post updates. You can configure the REST endpoint's response as custom output values, save it as a file, and attach it to the job. The custom output values can be used to retrieve tokens for subsequent REST calls, direct the workflow path, or be used as inputs for other steps.

When the step is run, the web request is sent to the REST endpoint defined in the step.

The step can be finished by clicking Complete Step .

Configure the step

Do the following to configure the step:

Caution:

To reduce security vulnerabilities, only configure the Send Web Request step for trusted web pages and web apps.

Create or edit a workflow diagram to access the Step Library panel.
Drag Send Web Request from the Step Library panel to a connection arrow of a step on the workflow canvas.
