If you’re in an app that offers a Venmo button, tap on it to authorize your purchase. You will then be prompted for permission to link your Venmo account with the merchant. Once linked, that merchant will have the ability to charge your linked Venmo account for future purchases in accordance with your agreement with the merchant. You can disconnect your Venmo account from the merchant at any time by going to "Settings" in Venmo and tapping on "Connected Merchants." Select the merchant you want to stop making purchases from, and tap "Disconnect" at the bottom of the screen.

Similarly to payments that you send to your friends, Venmo will first attempt to use money in your Venmo account when paying for your online purchase. If you do not have enough money in your Venmo account to cover the entire cost of the purchase, Venmo will charge the full amount to the card or bank account you have on file that you have designated for online purchases.

I disconnected my Venmo account from an app. Why does it still appear as a payment method in that app?
Even if you disconnect your Venmo account from a merchant’s app, it may still appear as a payment option if the merchant has not refreshed your account. However, the merchant won’t be able to charge your account if you’ve disconnected it through the Venmo app.
