When user click on the shopify link from my website (not shopify) I want to add products programmatically on cart and then take the user directly to the payment page.
Means I don't want user to go through a product selection process, I want app to do It all I want user to do is make a payment for the payable amount.
So the question is how to create a cart in your website/webapp and make user directly land on the checkout page in shopify store or what api to use.
thanks and open for suggestions.
