We are a POS and e-commerce software provider currently using shopify as our primary platform for e-commerce. We are developing a payments gateway and are looking to use our payments on our customer's shopify stores.
How do we do add our payments to our customer's shopify stores?
At the moment, the process for becoming a payment app on Shopify is still in beta - per our official documentation here and will become available in Q3 2021. For the time being, you can explore the extensive collection of resources, including requirements, guides, and more. If you are looking to stay up-to-date on developer related releases and updates like this, I'd also suggest subscribing to our Developer Changelog- Cheers!
