I used the Public Pet Store API, set up a custom REST connection with the base URL but without Swagger.json, and confirmed it needs no authentication. In Thunk, I enabled the GenericAPIGet tools from View Tools. Then I built a custom tool that gets a pet by ID by wrapping the underlying get call, and I tested it with pet ID 1. If you want, follow the same steps to create your own wrapped tool and run it in a workflow plan.
