DEVELOPER FIRST
Build Your Entire Billing & Customer Experience with One API
Manage customers, billing, usage, products, and support with a single, powerful REST API.
Why build with the RecurringStack API?
A Foundation for Growth
Our REST API provides all the necessary building blocks to create sophisticated subscription logic and billing workflows, tailored to your exact business needs.
Customer Management
Programmatically create and update customer accounts, manage contact details, and store custom fields with secure API calls.
Subscription Management
Programmatically create, modify, pause, and cancel subscriptions with simple API calls to automate the entire lifecycle.
Payments & Revenue
Process payments and retrieve payment records, revenue events, and transaction details programmatically.
Billing & Invoicing
Generate invoices, estimates, taxes, and billing totals programmatically with consistent API calls.
Clear & Consistent
A Platform You Can Build Anything On
We built the billing engine — customers, subscriptions, invoices, payments, usage. You get a predictable, resource‑oriented API with clean JSON/XML and intuitive URLs, so you can build fast without rebuilding the guts yourself.
- RESTful architecture for predictability.
- Standard HTTP response codes and verbs.
- Choose JSON or XML responses.
- Comprehensive and clear error messages.
