I am new in Shopify, I have developed an App in Shopify and wants to sale this app on the shopify store by using the recurring payment method but, I can not understand how to implement the recurring payment code in my app so that it will deduct the payment automatically from the customer account.
I have read discussion https://groups.google.com/forum/#!forum/shopify-app-discuss but still confused about when to use these API's and need to execute this API's every month to deduct the payment from the customer account.
We also recently released our app on the Shopify App Store. Here is the thing about Shopify's recurring billing piece - You only have to integrate with their billing gateway, define the price points, that's it. Shopify takes care of the monthly payments and the recurring billing.
