How do I get the fields generated by "Amazing Fields" via API?

I tried in several ways. Using “https://api.trello.com/1/cards/{id}/pluginData?key=APIKey&token=APIToken’”, but I don’t know if I’m getting the correct plugin ID, the only information I found about it of the same is the id generated by the requests “Get Enabled Power-Ups on Board” and “Get Power-Ups on a Board”
