Hi @leandrofelix
Generally, we should already support columns that appear in the metadata already. However, you will need to ensure that the "includecustomfields" (Include Custom Fields) is enabled in the Advanced Settings.
If the column/data doesn't appear, then it's likely the data isn't being represented in the Trello API, in which case we will not be able to retrieve those columns.
However, from some research it appears that Amazing Fields power-up has its own REST API, and if so our API connector can be used to interact with its API.
For more information on the authentication and the endpoints that can be used refer to the

Please let us know if you have any other questions.
