URL to open a CashApp payment?

Question

I'm building an app where I want users to be able click a link to open up CashApp (as well as various other P2P payment apps), as far along in the transaction as possible. My client doesn't want the app to actually handle the payments, just for it to forward along to a place to make the payment.

So, for example, I can go to venmo.com/username to open the Venmo app to a certain user's profile, which is basically enough for me. (anyone know how to include an amount or message in the url?)

But cash.app/username goes to a webpage that directs me to the App Store get the app, and doesn't even open the app on my phone if it's already downloaded.

Anyone know how to do this?

Answer 1

This is actually quite simple with a universal link:

https://cash.app/$username/amount

The following example will open a cash app payment of $12.50 for the user with username 'helloworld':

https://cash.app/$helloworld/12.50
