In the Smake backend you will find pre-installed payment systems, which you can use without having to install anything yourself. If you want to place orders through the Smake Workflow in the Smake Shop with Paypal as payment method, you only need your Paypal data.
Do you know Stripe? Stripe is a software platform for online payment processing. Currently Smake supports payments via Klarna Sofort, credit card and iDEAL via Stripe. To use these payment methods a Stripe account is mandatory. How to set up your Stripe or Paypal in your Smake backend you can read in our HelpCenter.
