How to integrate payment gateway within the shopify app

Hey everyone,

I need help in integrating the payment gateway, I want to integrate PayPal payment gateway(end-to-end) in the app which i have already created. The payment should be to subscribe on monthly basis for the app’s service.

Note: The requirement is not to integrate payment gateway to the shopify store or the payment gateway should not be a separate app itself

Thank you

Hi @abhishek-pgagi !

Are we talking about integrating your Paypal payment gateway to your Shopify billing in order for your monthly Shopify subscription invoice to be automatically invoiced to your Paypal account? If so, you will need to go to your >settings >billing >manage >add payment method >Paypal. Once connected as primary payment method, on the day of your invoiced due date, it will be automatically deducted on your primary payment method given if it has sufficient amount for the transaction.
