Loyverse
Add Loyverse to your product for your customers, and give your AI agents governed access to it.
Embed a Loyverse integration so merchants can connect their own point of sale and see their sales inside your product, with no per-merchant build on your side. Each merchant authorises their own Loyverse account, so receipts, items, customers and stock are read and written under their credentials and stay scoped to them. Writes are idempotent, so a retry after a timeout cannot duplicate a record, and a new receipt can trigger your product as the sale lands rather than in a nightly batch. fastn owns the auth, token refresh, pagination and API upkeep, and the same governed connection gives your AI agents scoped, audited access.
In your product
Embedded for your customers. Per-tenant auth, no per-customer code, maintained by fastn.
Let merchants connect their own Loyverse account so receipts, items and customers appear in your product without a per-merchant build.
Read stock levels and adjust inventory so your product is not making decisions on a stale count.
React to a new Loyverse receipt with an event trigger so loyalty, accounting or fulfilment steps run as the sale lands.
Support merchants running several stores, with every read and write scoped to the account that authorised it.
For your AI agents
Governed, audited access for the agents you build, through the MCP server.
An agent answers what sold yesterday by reading that merchant's own receipts, not an aggregate.
An agent updates an item or its price within scoped permissions, with the write idempotent and audited.
An agent flags items about to run out and shows the sales behind the forecast.

- 02Have each merchant authorise their own Loyverse account so calls run under their credentials.
- 03Map the receipt, item, customer and inventory fields your product uses, then enable triggers.
- 04Call it from your product and expose the same connection to your agents through the MCP gateway.
Why teams use the Loyverse integration
What you get by embedding it with fastn instead of building it yourself.
- Ship a Loyverse integration without building it. Your customers connect their own Loyverse 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 Loyverse update is not your on-call problem.
- One integration serves your product and your agents. The same governed Loyverse 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.

DocusignLoyverse integration FAQ
How do I add a Loyverse integration to my product?
Enable the Loyverse connector in your fastn dashboard, then let each customer authenticate their own Loyverse account. fastn handles the OAuth flow, token storage and refresh per tenant, so there is no Loyverse client code in your app and no per-customer branch in your codebase. Setup is 4 steps.
Do my customers each connect their own Loyverse account?
Yes. Every connection is scoped to the individual customer, so each authorises their own Loyverse 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 Loyverse 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 answers what sold yesterday by reading that merchant's own receipts, not an aggregate.
Who maintains the Loyverse integration?
fastn does. When Loyverse 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 Loyverse 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 Loyverse integration?
A common starting point: let merchants connect their own Loyverse account so receipts, items and customers appear in your product without a per-merchant build. 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 Loyverse integration cost?
It is included. Pricing is based on connected accounts, not on how many connectors you enable, so adding Loyverse does not change your per-connector cost. You can start free with 3 connected accounts.
