Main issue: Whether Shop Pay can be used without participating in the Shop app, as the merchant has their own mobile client and wants faster checkout.
Key answer:

Outcome/Status:
I am curious to know if this is possible since I am new to Shopify. We want to use Shop Pay but aren’t interested in participating in the Shop app at all especially when we have our own mobile client. We want to use Shop Pay given the shorter checkout time it entails for customers.
I would appreciate any answers that can be helpful! Thank you to those who answer! 
Hey, @jazilzaim !
It’s possible to use Shop Pay on your store as a standalone payment method on your store without the Shop Pay App as it is an accelerated payment method.
On this page here, you’ll find information on how to activate Shop Pay on your store for your customers.
To ensure you receive payouts through Shop Pay, make sure to complete the setup process by providing your business details and banking information. If you didn’t finish the setup when activating Shop Pay, remember to complete it within 21 days of receiving your first payment. Failure to complete the setup within this timeframe will result in automatic refunds of all payments to customers.
In addition to that, you might find this blog on Shop Pay helpful to read. Let me know if there is anything else I can help with.
