Amazon Seller Central
Add Amazon Seller Central to your product for your customers, and give your AI agents governed access to it.
Embed an Amazon Seller Central integration so your customers can work their own orders, listings, inventory, and settlement reports from inside your product, with governed agent access to the same records. Writes are idempotent so a retry cannot duplicate an order action, and every call is logged per tenant for reconciliation. fastn handles each seller's authorisation and API upkeep, so onboarding a new marketplace account is configuration rather than a release.

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

QuickBooksAmazon Seller Central integration FAQ
How do I add an Amazon Seller Central integration to my product?
Enable the Amazon Seller Central connector in your fastn dashboard, then let each customer authenticate their own Amazon Seller Central account. fastn handles the OAuth flow, token storage and refresh per tenant, so there is no Amazon Seller Central client code in your app and no per-customer branch in your codebase. Setup is 4 steps.
Do my customers each connect their own Amazon Seller Central account?
Yes. Every connection is scoped to the individual customer, so each authorises their own Amazon Seller Central 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 Amazon Seller Central 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 an order and its shipment status before answering a seller question.
Who maintains the Amazon Seller Central integration?
fastn does. When Amazon Seller Central 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 Amazon Seller Central 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 Amazon Seller Central integration?
A common starting point: read orders and order items into your product, mapped to their own 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 Amazon Seller Central integration cost?
It is included. Pricing is based on connected accounts, not on how many connectors you enable, so adding Amazon Seller Central does not change your per-connector cost. You can start free with 3 connected accounts.
