Hey Brandon!
Right now, Parabola cannot be used to connect to Amazon APIs. The reason is that they require an HMAC signature, which has to be generated right when the request is sent. Parabola cannot generate those signatures yet!
Perhaps head over to #feature-requests and submit a request support for HMAC signatures! Specifically to connect to Amazon.
There are a few wrapper APIs that folks have hosted over at https://rapidapi.com/search/amazon that maybe could help
