EasyPost
Add EasyPost to your product for your customers, and give your AI agents governed access to it.
Embed an EasyPost integration so your customers can rate, buy, and track shipments from inside your product using their own account and their own carrier arrangements. Tracking data arrives from many carriers in inconsistent formats and at unpredictable times, so tracking events are normalised and delivered per tenant, and label purchases are idempotent so a retry does not buy the same label twice. fastn handles each customer's credentials and API upkeep.
In your product
Embedded for your customers. Per-tenant auth, no per-customer code, maintained by fastn.
Let customers compare carrier rates and buy labels inside your product with their own account.
Create shipments and return labels from an order or job in your product without a separate tool.
Read trackers so delivery status shows against the record it belongs to in your app.
Trigger your product when a tracking event lands or a delivery exception is raised.
For your AI agents
Governed, audited access for the agents you build, through the MCP server.
An agent reads a shipment's tracking events before answering a where-is-my-order question.
An agent buys a label or creates a return within governed permissions, with the action audited.
An agent reacts to a delivery exception and starts the customer's recovery workflow.
Example prompt
List shipments created this week with no tracking movement in 72 hours and show the carrier and service for each.

- 02Have each customer authenticate their EasyPost account with their own API key.

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

XeroEasyPost integration FAQ
How do I add an EasyPost integration to my product?
Enable the EasyPost connector in your fastn dashboard, then let each customer authenticate their own EasyPost account. fastn handles the OAuth flow, token storage and refresh per tenant, so there is no EasyPost client code in your app and no per-customer branch in your codebase. Setup is 4 steps.
Do my customers each connect their own EasyPost account?
Yes. Every connection is scoped to the individual customer, so each authorises their own EasyPost 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 EasyPost 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 a shipment's tracking events before answering a where-is-my-order question.
Who maintains the EasyPost integration?
fastn does. When EasyPost 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 EasyPost 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 EasyPost as things move?
Whatever EasyPost 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 EasyPost integration?
A common starting point: compare carrier rates and buy labels inside your product with their own account. 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 EasyPost integration cost?
It is included. Pricing is based on connected accounts, not on how many connectors you enable, so adding EasyPost does not change your per-connector cost. You can start free with 3 connected accounts.
