Platform Overview

Apt Commerce is a modern payment processing platform designed for merchants and SaaS partners. Our platform provides:

Multi-method payments — Accept cards (Visa, Mastercard, Amex), ACH/bank transfers, and stablecoin payments through a single integration.
JSON-first API — All requests and responses use application/json. Resource IDs use prefixed UUIDs (txn_, cust_, inv_).
Cursor-based pagination — List endpoints return { "data": [...], "has_more": true, "next_cursor": "..." }.
Progressive onboarding — Start with gateway-only access and unlock additional payment methods as your business grows.
Partner platform — Embed payment onboarding into your SaaS product with our Partner API for sub-merchant management.
Developer-first — RESTful API, webhook events, official SDKs, and comprehensive testing tools.
