Hello! We are Devoxen, a company with extensive experience in similar projects, particularly in working with Shopify Apps, Shopify API, OAuth, webhooks, and custom integrations for payment solutions.
We have a good understanding of the specifics of such tasks: implementing authorization within a Shopify plugin, refining back-end logic, integrating the front-end part through Hydrogen and Polaris, as well as ensuring correct interaction with already existing plugins without conflicts. We can also pay special attention to secure data transmission, stable operation with the API, and preparing clear documentation for integration.
I suggest we move to private messages for a more detailed discussion of the technical specifications, deadlines, and costs.
