Syrinx
Add Syrinx to your product for your customers, and give your AI agents governed access to it.
Syrinx is hire and rental management software from Higher Concept Software, now sold as Syrinx 365 under Point of Rental, and it runs the operational core of plant, tool and equipment hire businesses. What makes rental different from retail is that the thing sold is the same asset over and over: a contract books a fleet item for a period, availability depends on when it comes back, and the charge accrues by duration rather than at a single checkout, with off-hire, damage and re-hire all changing the money after the order was placed. Multi-branch is the norm, so which depot an item belongs to is part of every question about availability. Writes are idempotent, because a duplicate contract against one asset is a double booking somebody unpicks in person.
In your product
Embedded for your customers. Per-tenant auth, no per-customer code, maintained by fastn.
Let each hire company connect their own Syrinx system so contracts and availability are visible inside your product.
Check whether a fleet item is free for a date range at a given depot before your product promises it.
Raise or amend a hire contract from your product, idempotently, so one asset is never double booked.
Read off-hire, damage and re-hire changes so the charge your product shows matches what will actually be invoiced.
For your AI agents
Governed, audited access for the agents you build, through the MCP server.
An agent answers what is available at a depot next week and what is already committed.
An agent extends or off-hires a contract within scoped permissions, with the change attributed.
An agent explains why a hire cost more than quoted by reading the contract's own amendments.
Example prompt
What is on hire from this depot next week, and which items are due back but not yet off-hired?
Set up Syrinx in 4 steps
- 01Enable the Syrinx connector in your fastn dashboard.
- 02Have each hire company supply credentials for their own Syrinx system, and confirm whether it is hosted or runs on their own servers.
- 03Map the contract, fleet item, depot and customer fields that business uses, then enable the writes you need.
- 04Call it from your product and expose the same connection to your agents through the MCP gateway.
Why teams use the Syrinx integration
What you get by embedding it with fastn instead of building it yourself.
- Ship a Syrinx integration without building it. Your customers connect their own Syrinx 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 Syrinx update is not your on-call problem.
- One integration serves your product and your agents. The same governed Syrinx 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.

DocusignSyrinx integration FAQ
How do I add a Syrinx integration to my product?
Enable the Syrinx connector in your fastn dashboard, then let each customer authenticate their own Syrinx account. fastn handles the OAuth flow, token storage and refresh per tenant, so there is no Syrinx client code in your app and no per-customer branch in your codebase. Setup is 4 steps.
Do my customers each connect their own Syrinx account?
Yes. Every connection is scoped to the individual customer, so each authorises their own Syrinx 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 Syrinx 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 is available at a depot next week and what is already committed.
Who maintains the Syrinx integration?
fastn does. When Syrinx 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 Syrinx 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 Syrinx integration?
A common starting point: let each hire company connect their own Syrinx system so contracts and availability are visible 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 Syrinx integration cost?
It is included. Pricing is based on connected accounts, not on how many connectors you enable, so adding Syrinx does not change your per-connector cost. You can start free with 3 connected accounts.
