I am one of the shopify developer trying to create custom payment gateway app using third party API on shppify
Unfortunately, I am having difficulties in developing apps for that payment gateway although I followed all the guidelines
which are provided by shopify to work on app creation,
Shopify system asks to fill the payment partnership like for familiar payment gateway providers Paypal, Stripe etc,
but as I am developer not needed to partnering, just I am going to create app with functioning of get the payment
along with order details and send to the third party payment page, then complete it and return back to site with success message.
Please guide me to resolve this issue
