Integration Guide

Build the payment flow without losing the product story.

This page gives the site a developer-facing anchor: how to create checkout sessions, what channels the gateway supports, and how merchants receive status events from the platform.

Why this page matters

The integration guide is the page that makes the whole site feel like a product instead of only a visual concept. It gives founders, engineers, and potential partners enough implementation detail to understand how the gateway could actually be used.
