FAQ

Can I integrate halfin into my own product instead of a hosted page?

Yes. halfin is spec-first: you can run the hosted checkout, or render your own checkout against the same REST API and keep the customer inside your product. Either way the on-chain detail stays on halfin's side, and a signed webhook is the source of truth for marking an order paid — verify the HMAC signature before acting on it.
