Hi @ianxxx, this is a field of services I haven’t looked into into too much (though playing with banking APIs is still somewhere on my personal to-do list). I don’t think a node exists for any such services yet, but in theory you should be able to connect to any REST API through the HTTP Request node. The node supports a variety of authentication methods.
So you might want to try out any of these services that seems suitable to you and share your experience in order to help fellow n8n users.
