Currently, VWO Engage (formerly PushCrew) payment platform only accepts Credit/Debit cards.
But, you can transfer funds from your PayPal account to VWO Engage. Here's how.
1) Generate a PayPal Master Card
Generate a PayPal Master Card, which has absolutely zero fees. You can learn more about this by visiting PayPal's website.
2) Use your PayPal card number as a Credit card
Once you obtain a PayPal card number, after following the process on the PayPal website, you can use this card number like an ordinary credit card. This way, you can make payments on our platform (and anywhere else). The money would be transacted from your PayPal account itself.
