Hello, this probably should be done on the backend as the GitHub package you sent is a Node.js one, and also for security, you might want to handle this on the backend. I don’t know Plaid very well, so I can’t tell, but sounds like it should be handled on the backend. You could use Fastgen, they let you do no-code Workflows and use custom Node.js packages to enrich it as WeWeb does basically.
Or if you’re feeling like coding a little, I think Supabase’s Edge Functions could handle this kind of task.
PS: If you need a discount for Fastgen, I have a ref link, feel free to reach out
