Developer API & Webhooks

Sooner or later every serious rental business needs to get data in or out programmatically — a corporate customer wants a feed, a BI tool wants the numbers, an internal script needs to create orders.

Renttix exposes a versioned REST API for exactly that. Customers, orders, products, and the other core resources are available over clean JSON endpoints under /api/v1, with documentation served from the platform itself rather than a PDF from two versions ago.

Access runs on API keys you create and manage in the developer portal. Keys can be revoked instantly, and every key is scoped to your workspace — there is no master credential floating around a contractor's laptop.

Rate limits and logging are built into the same layer your own interface uses, so API traffic is governed and observable rather than a side door.

Integrations that poll for changes are slow when you need them fast and wasteful the rest of the time. Webhooks invert the relationship: Renttix tells your systems the moment something happens.

Register webhook endpoints for the events you care about and your systems receive a signed payload when they fire — an order created from your website can reach your CRM before the confirmation email reaches the customer.

Endpoints are managed alongside your API keys in the developer portal, and each delivery is logged so a missed message is a lookup, not a mystery.

Together with the API, webhooks make Renttix a platform you build on rather than a box you copy data out of. The system of record stays the system of record, and everything else stays in sync.

Every integration eventually has its 3am question: what exactly did the system receive, and what did it answer?

The developer portal keeps request logs for API traffic — what was called, by which key, with what result — so debugging an integration is reading a log, not reconstructing events from both ends of a phone call.

The same discipline applies to the platform's own outbound connections. Accounting syncs, payment provider calls, and webhook deliveries are recorded, giving you a paper trail across every system boundary.

For businesses with development teams, this is the difference between a vendor and a platform: the machinery is inspectable, the credentials are yours to rotate, and the data is reachable the moment you need it somewhere else.
