ChannelEngine
Add ChannelEngine to your product for your customers, and give your AI agents governed access to it.
Embed a ChannelEngine integration so your customers can work their own marketplace orders, listings, and offers 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 so a transaction can be reconciled against the event that triggered it. fastn handles each customer's credentials and API upkeep, so onboarding another seller account is configuration rather than a release.
In your product
Embedded for your customers. Per-tenant auth, no per-customer code, maintained by fastn.
Let customers read marketplace orders and order lines into your product, mapped to their own records.
Read and update listings and offers so sellers manage channel pricing and stock inside your product.
Read offer and channel status so your product does not act on a stale marketplace picture.
Trigger your product when an order is placed, cancelled, or a return is registered.
For your AI agents
Governed, audited access for the agents you build, through the MCP server.
An agent looks up an order and its channel status before answering a seller question.
An agent updates an offer price or stock level within governed permissions, with the action audited.
An agent reacts to a new marketplace order and starts the fulfilment workflow.
Example prompt
List orders from the last three days that have not been acknowledged and group them by channel.
Set up ChannelEngine in 4 steps
- 01Open the ChannelEngine connector from your fastn dashboard.
- 02Have each customer authenticate their ChannelEngine account with least-privilege credentials.
- 03Map the order, listing, and offer 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 ChannelEngine integration
What you get by embedding it with fastn instead of building it yourself.
- Ship a ChannelEngine integration without building it. Your customers connect their own ChannelEngine 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 ChannelEngine update is not your on-call problem.
- One integration serves your product and your agents. The same governed ChannelEngine 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.

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