i am planning to use a third party checkout (like gokwik, shopflo) on my shopify store. A lot of shopify sites (like justherbs.in etc.) are seemingly using them to bypass shopify transaction costs without any issues
my questions are
Do I need special permission to use these checkout apps as they are not on shopify app store
am I violating any terms of service by using these apps
do I need to pay anything to shopify to use them as It appears I won’t be paying any per order transaction charges to shopify
