Shopify custom API integration

Job ID: 34071274

Budget: $30 – $250 USD

Need someone to integrate PayFast API Recurring Billing into Shopify checkout. PayFast API: https://developers.payfast.co.za/docs

1. There should be 5 variants for all products: Once-Off, Monthly, Quarterly, Bi-Annually, and Annually.

2. When a customer adds a product to their cart and selects Quarterly, all future products can then only display the variant options Once-Off and Quarterly. So if they add a product to a clean cart with the variant option "Monthly" then all future products will only display Once-Off and Monthly as an option. So in essence the customer will be able to select Once-Off at all times or the X variant option.



3. On checkout Shopify should send an instruction to the PayFast API;

- A total amount for the entire cart including the shipping value.
- Recurring API: A total value for all the items that had "Monthly, Quarterly, Bi-Annually, and Annually" selected option.


That is all that I require for now. If you can do this I will use you in the future.
