Allow Merchants to Connect their Stripe Account to your App
To enable consumer payments to go to your Merchant's Stripe accounts. You need to create a screen in your app where Merchants can connect their Stripe account to your app.

Add a Stripe ID property to your Merchants Collection in your database.

1) In Adalo, in the left tool bar, click the Database Tab
2) Find and expand the Merchant Collection (or create one if you haven't already)
3) Click Add Property, then choose Text as the type of property
4) Name the new property "Stripe Account Id"
