It looks like you have an Venmo integration ("Sent to Venmo" in screenshots) which I haven't quite cracked yet - curious if you're willing to talk about how it works. Tender has venmo via plaid, but it only supports importing tx, not initiating payments/requests.
I thought about either: - Integrating unofficially (https://github.com/mmohades/VenmoApiDocumentation) - Just doing links to venmo payment (i.e. venmo.com/user?pay=500) and having some way to import venmo contacts
Neither seems great from a UX or security perspective.
I wrote about how it works here: https://gabeoleary.com/posts/venmo-deeplinking-including-fro...
When I wrote this it only worked on mobile. The deep link would take one into the app with the amount/details etc prefilled out. Just tested and it looks like the same format works on desktop now too.
I had until just now not realized that Plaid has a Venmo integration.
I could imagine using the deep link to begin the transaction and then using the plaid connection to look for it's completion...
I created a tool that helps people stay on top of shared transactions (https://reconcile.app/) a few years ago and have recently been working on another iteration of it that has some similarities to what you've built, but with a focus on couples who share much of but not all of their financial lives.
