Presentation allows you to define how data will be presented within the workflow builder. The primary use is to create Entity URLs, so that you can test and validate data easily while building a workflow.
Entity URL
When you run an action on the workflow screen, such as List Users, and you view the output, we want to include links on every user that open a new tab in the target system, on the exact page of that resource. This lets us view the data we are working with when integration systems very rapidly and is an essential tool.
Entity url has access to the response attributes, so you can interpolate data, for example:
https://acme.co/users/{{input.userId}}
