Subscription Management API
Unified Subscription Management API
Knit makes it simpler and faster to add multiple Subscription Management integrations to your app with a single API
What is a Unified Subscription Management API?
Subscription Management platforms each store data differently, with their own authentication and schemas. A Unified Subscription Management API standardizes these into one interface, while Knit manages translation, rate limiting, retries, and sync management underneath.

Knit shipped a brand-new Timesheet API in a week and handed us a ready-to-use NetSuite sandbox. That velocity is priceless when you're running payroll in 40+ countries.

FAQ
Common questions about the Unified Subscription Management API
Which Subscription Management systems does Knit support?
1 Subscription Management platforms today — including Chargebee and more. Missing one you need? Knit's AI-assisted connector-build process typically adds a new one within days.
Does the Subscription Management API support both reading and writing data?
Yes. It supports both reads and writes, so you can build bi-directional sync use cases — not just pull Subscription Management data, but push updates back to the source app.
How does authentication work across Subscription Management platforms?
Knit provides an embedded Auth component (white-labeling available on higher tiers) that handles OAuth, credential storage, and refresh — your customers authorize once through Knit, and you never touch raw credentials.
What is the timeline for adding a missing Subscription Management connector?
Typically days, not months — the same AI-based connector-build tooling that lets us maintain the 1 Subscription Management connectors already live.
Do you store Subscription Management data or customer PII?
No. Knit acts as a stateless passthrough — data is processed on our application server and sent directly to your webhooks, without being stored on Knit's servers.
What is the pricing model, and is there a free trial?
You choose the model that fits your business — pricing based on integrated accounts, or based on API call volume. Every plan includes a 30-day free trial before billing starts.
