Extensiv
Add Extensiv to your product for your customers, and give your AI agents governed access to it.
Embed an Extensiv integration so your customers can work their own orders, items, inventory levels, warehouses, and shipments from inside your product. Fulfilment data arrives at unpredictable times and in different shapes per warehouse, so mapping is configuration per customer and stock can be read on demand or kept in step through events rather than a stale nightly count. fastn handles per-tenant authorisation and API upkeep, so onboarding another warehouse or client 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 connect their own Extensiv account so orders and stock appear inside your product.
Create and update orders from your product so fulfilment starts without a manual re-entry step.
Read inventory levels per warehouse so your product is not promising stock that is not there.
Trigger your product when an order ships, a shipment is updated, or inventory crosses a threshold.
For your AI agents
Governed, audited access for the agents you build, through the MCP server.
An agent reads order and shipment status before answering a customer service question.
An agent creates or updates an order within governed permissions, with the action logged.
An agent reacts to a low stock event and starts the replenishment step.
Example prompt
List orders that have not shipped within their promised window and show the warehouse handling each.
Set up Extensiv in 4 steps
- 01Open the Extensiv connector from your fastn dashboard.
- 02Have each customer authenticate their own Extensiv account.
- 03Map the warehouses, order fields, and inventory data 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 Extensiv integration
What you get by embedding it with fastn instead of building it yourself.
- Ship an Extensiv integration without building it. Your customers connect their own Extensiv account inside your product and work their shipments, tracking events and orders there, with no per-customer code on your side.
- Handle the part that actually costs time: tracking data arrives from many carriers in inconsistent formats and at unpredictable times. fastn owns the auth, token refresh, rate limits, pagination and breaking-change fixes, so an Extensiv update is not your on-call problem.
- One integration serves your product and your agents. The same governed Extensiv connection powers in-product features and gives AI agents scoped, audited access, so you keep physical movement and stock visible inside your product without wiring it twice.

QuickBooksExtensiv integration FAQ
How do I add an Extensiv integration to my product?
Enable the Extensiv connector in your fastn dashboard, then let each customer authenticate their own Extensiv account. fastn handles the OAuth flow, token storage and refresh per tenant, so there is no Extensiv client code in your app and no per-customer branch in your codebase. Setup is 4 steps.
Do my customers each connect their own Extensiv account?
Yes. Every connection is scoped to the individual customer, so each authorises their own Extensiv account and only ever sees their own shipments, tracking events and orders. 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 Extensiv 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 order and shipment status before answering a customer service question.
Who maintains the Extensiv integration?
fastn does. When Extensiv 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.
Can I track shipments from Extensiv inside my product?
Yes. Shipment and tracking events are read per customer and can trigger your workflows, so status changes surface in your product instead of your users checking a carrier site.
What does my product get back from Extensiv as things move?
Whatever Extensiv actually holds. Where it moves goods, that is shipment and tracking events, read per customer and delivered as they land. Where it holds stock, levels can be read on demand or kept in step through events, so your product is not deciding on a stale count. Where it carries orders and documents between trading partners, it is the acknowledgement, ship notice or status change that says what moved.
What can I build with the Extensiv integration?
A common starting point: connect their own Extensiv account so orders and stock appear inside your product. 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 Extensiv integration cost?
It is included. Pricing is based on connected accounts, not on how many connectors you enable, so adding Extensiv does not change your per-connector cost. You can start free with 3 connected accounts.
