Etsy
Add Etsy to your product for your customers, and give your AI agents governed access to it.
Embed an Etsy integration so your customers can work their own shops, listings, receipts, transactions, and inventory from inside your product. Order and payment state must never be double-applied, so writes are idempotent and every call is logged per tenant, which is what makes a transaction reconcilable against the event that triggered it. fastn handles per-seller authorisation and API upkeep, so onboarding another shop is configuration rather than a release.
In your product
Embedded for your customers. Per-tenant auth, no per-customer code, maintained by fastn.
Let sellers connect their own Etsy shop so listings and orders appear in your product without a bespoke build.
Read receipts and transactions per seller so your product reports on real order and revenue data.
Create and update listings, prices, and inventory quantities from your product so sellers manage stock in one place.
Trigger your product when an order is placed, shipped, cancelled, or refunded.
For your AI agents
Governed, audited access for the agents you build, through the MCP server.
An agent reads recent orders and listing performance before answering a seller's question.
An agent updates a listing or inventory level within governed permissions, with the action logged.
An agent reacts to a new order and starts the fulfilment step.
Example prompt
Show listings that sold out this week and list the orders still waiting to ship.

Why teams use the Etsy integration
What you get by embedding it with fastn instead of building it yourself.
- Ship an Etsy integration without building it. Your customers connect their own Etsy 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 an Etsy update is not your on-call problem.
- One integration serves your product and your agents. The same governed Etsy 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.

DocusignEtsy integration FAQ
How do I add an Etsy integration to my product?
Enable the Etsy connector in your fastn dashboard, then let each customer authenticate their own Etsy account. fastn handles the OAuth flow, token storage and refresh per tenant, so there is no Etsy client code in your app and no per-customer branch in your codebase. Setup is 4 steps.
Do my customers each connect their own Etsy account?
Yes. Every connection is scoped to the individual customer, so each authorises their own Etsy 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 Etsy 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 recent orders and listing performance before answering a seller's question.
Who maintains the Etsy integration?
fastn does. When Etsy 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 Etsy 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 Etsy integration?
A common starting point: let sellers connect their own Etsy shop so listings and orders appear in your product without a bespoke build. 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 Etsy integration cost?
It is included. Pricing is based on connected accounts, not on how many connectors you enable, so adding Etsy does not change your per-connector cost. You can start free with 3 connected accounts.
