Lightspeed Commerce
Add Lightspeed Commerce to your product for your customers, and give your AI agents governed access to it.
Embed a Lightspeed Commerce integration so your merchants can connect their own store and have your product work their catalogue and orders directly. Writes are idempotent, so a retry after a timeout cannot duplicate an order, and every call is logged per tenant so a transaction can be reconciled against the event that triggered it. fastn handles per-merchant OAuth, token refresh, pagination and API upkeep.
In your product
Embedded for your customers. Per-tenant auth, no per-customer code, maintained by fastn.
Let merchants connect their own Lightspeed account so your product reads their products, orders and customers.
Create or update products and prices from your product, so a catalogue change happens once.
React to a new order or refund so fulfilment, entitlement or accounting steps run as soon as it lands.
Read customer and order history so your product answers a question without a second login.
For your AI agents
Governed, audited access for the agents you build, through the MCP server.
An agent looks up an order and its status before replying to a shopper query.
An agent updates a product or price within governed permissions, with each write audited.
An agent reacts to a refund and starts the next step of a workflow.
Example prompt
Show orders placed in the last seven days that are still unfulfilled and total their value.
Set up Lightspeed Commerce in 4 steps
- 01Open the Lightspeed Commerce connector from your fastn dashboard.
- 02Have each merchant authorise their own Lightspeed account with OAuth.
- 03Map the products, orders and customer 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 Lightspeed Commerce integration
What you get by embedding it with fastn instead of building it yourself.
- Ship a Lightspeed Commerce integration without building it. Your customers connect their own Lightspeed Commerce 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 Lightspeed Commerce update is not your on-call problem.
- One integration serves your product and your agents. The same governed Lightspeed Commerce 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.

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