Braintree
Add Braintree to your product for your customers, and give your AI agents governed access to it.
Embed a Braintree integration so your customers can take payments, manage payment methods, and issue refunds from their own Braintree merchant account inside your product, with governed agent access to the same records. Writes are idempotent, so a retry after a timeout cannot double-charge or duplicate a refund, and every call is logged per tenant so a transaction can be reconciled against the event that triggered it. fastn handles each merchant's credentials and API upkeep.
In your product
Embedded for your customers. Per-tenant auth, no per-customer code, maintained by fastn.
Let customers connect their own Braintree merchant account so payments settle to them, not through you.
Create and capture transactions and issue refunds from your product with idempotent writes.
Store and manage customers and their payment methods in the vault so repeat billing works in your product.
Trigger your product on successful payments, disputes, and refunds so entitlement and accounting steps run immediately.
For your AI agents
Governed, audited access for the agents you build, through the MCP server.
An agent looks up a transaction and its status before answering a billing question.
An agent issues a refund within governed permissions and spend limits, with the action audited.
An agent reacts to a dispute event and assembles the evidence for a human to submit.
Example prompt
Find declined transactions from the last seven days over 100 and group them by decline reason.
Set up Braintree in 4 steps
- 01Open the Braintree connector from your fastn dashboard.
- 02Have each customer connect their own Braintree merchant account with least-privilege API keys.
- 03Map the transaction, customer, and payment method 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 Braintree integration
What you get by embedding it with fastn instead of building it yourself.
- Ship a Braintree integration without building it. Your customers connect their own Braintree 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 Braintree update is not your on-call problem.
- One integration serves your product and your agents. The same governed Braintree 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.

QuickBooksBraintree integration FAQ
How do I add a Braintree integration to my product?
Enable the Braintree connector in your fastn dashboard, then let each customer authenticate their own Braintree account. fastn handles the OAuth flow, token storage and refresh per tenant, so there is no Braintree client code in your app and no per-customer branch in your codebase. Setup is 4 steps.
Do my customers each connect their own Braintree account?
Yes. Every connection is scoped to the individual customer, so each authorises their own Braintree 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 Braintree 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 looks up a transaction and its status before answering a billing question.
Who maintains the Braintree integration?
fastn does. When Braintree 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 Braintree 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 Braintree integration?
A common starting point: connect their own Braintree merchant account so payments settle to them, not through you. 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 Braintree integration cost?
It is included. Pricing is based on connected accounts, not on how many connectors you enable, so adding Braintree does not change your per-connector cost. You can start free with 3 connected accounts.
