Chargebee
Add Chargebee to your product for your customers, and give your AI agents governed access to it.
Embed a Chargebee integration so your customers can manage their own subscriptions, invoices, customers, and plans from inside your product, with governed agent access to the same billing records. Writes are idempotent so a retry after a timeout cannot create a duplicate subscription or invoice, and every call is logged per tenant so a charge can be reconciled against the event that triggered it. fastn handles per-customer authorisation and API upkeep.
In your product
Embedded for your customers. Per-tenant auth, no per-customer code, maintained by fastn.
Let customers read their own subscriptions, plans, and invoices into your product, mapped to their records.
Create, upgrade, downgrade, and cancel subscriptions from inside your product without a billing rebuild.
Read invoices and payment status so entitlement decisions in your product run on current billing state.
Trigger your product when a subscription changes, an invoice is paid, or a payment fails.
For your AI agents
Governed, audited access for the agents you build, through the MCP server.
An agent reads a customer's subscription and invoice history before answering a billing question.
An agent applies a plan change or issues a credit within governed permissions, with the action audited.
An agent reacts to a failed payment and starts the dunning workflow.
Example prompt
List subscriptions with a failed payment in the last week and show the invoice amount outstanding for each.
Set up Chargebee in 4 steps
- 01Open the Chargebee connector from your fastn dashboard.
- 02Have each customer authenticate their Chargebee site with least-privilege credentials.
- 03Map the subscription, plan, and invoice fields your product uses, then enable actions and triggers.
- 04Call them from your product, or expose them to an agent through the MCP server.
Why teams use the Chargebee integration
What you get by embedding it with fastn instead of building it yourself.
- Ship a Chargebee integration without building it. Your customers connect their own Chargebee account inside your product and work their orders, payments and customers there, with no per-customer code on your side.
- Handle the part that actually costs time: money and order state must never be double-applied, and reconciliation has to be possible. fastn owns the auth, token refresh, rate limits, pagination and breaking-change fixes, so a Chargebee update is not your on-call problem.
- One integration serves your product and your agents. The same governed Chargebee connection powers in-product features and gives AI agents scoped, audited access, so you keep commerce and payment records in step with your product without wiring it twice.

QuickBooksChargebee integration FAQ
How do I add a Chargebee integration to my product?
Enable the Chargebee connector in your fastn dashboard, then let each customer authenticate their own Chargebee account. fastn handles the OAuth flow, token storage and refresh per tenant, so there is no Chargebee client code in your app and no per-customer branch in your codebase. Setup is 4 steps.
Do my customers each connect their own Chargebee account?
Yes. Every connection is scoped to the individual customer, so each authorises their own Chargebee account and only ever sees their own orders, payments and customers. That per-tenant isolation is the point of an embedded integration: you support the long tail of customer setups without maintaining an integration per customer.
Can AI agents use this Chargebee integration?
Yes. The same connection is exposed to your agents through the fastn MCP gateway, with permissions scoped per tenant and every call audited. An agent reads a customer's subscription and invoice history before answering a billing question.
Who maintains the Chargebee integration?
fastn does. When Chargebee changes an endpoint, deprecates a field or alters its auth, the fix lands in the connector rather than in your backlog, and your customers' connections keep working.
Is the Chargebee integration safe for payment and order writes?
Writes are idempotent, so a retry cannot double-charge or duplicate an order, and every call is logged per tenant so a transaction can be reconciled against the event that triggered it.
Can my product react to a new order, payment or refund immediately?
Yes, through event triggers, so fulfilment, entitlement or accounting steps run as soon as the event lands rather than on a nightly sync.
What can I build with the Chargebee integration?
A common starting point: read their own subscriptions, plans, and invoices into your product, mapped to their records. Teams also use it for the other use cases listed above, and expose it to agents for governed reads and writes.
How much does the Chargebee integration cost?
It is included. Pricing is based on connected accounts, not on how many connectors you enable, so adding Chargebee does not change your per-connector cost. You can start free with 3 connected accounts.
