Services
You can invoke third-party SOAP or REST services from your transactions. This tab shows services that have already been created and are available for consuming, and divides them in two categories: API SOAP and API REST.
To include a service in your transaction flow, go to the REST or SOAP category, drag the service you need to invoke and drop it into the canvas to connect it to the necessary actions.
When you set a SOAP service as an action, you need to edit its properties as shown in the image below:
Re-select the service in the External Service drop-down menu, and select the desired option in the Method drop-down menu. The action values fill out automatically.
