Adding a body transformation using the endpoint designer is very straightforward, you can use the same examples that are set out in the API Definition Object configuration transformation documentation with the dashboard.
Step 1: Create the transform
Create a new Endpoint and select the Body Transforms plugin.
Step 2: Define the transform
Select your input type, and then add the template you would like to use to the Template input box.
Step 3: Test the transform
If you have sample input data, you can use the input box to add it, and then test it using the Test button.
As you can see from the screenshot above, we’ve already done this and you can see the sample output of the transformation in the Output field.
