Start from activity you can trust
Engine verifies the provider signature, handles the challenge, and classifies the event type before anything reaches your application.
A payment clears, an issue moves, a subscription lapses. Fused verifies it, queues it, and delivers it to the application that asked for it—so your team writes the response and not, once again, the retry loop.
From provider activity to a product moment
A payment, an issue, a lifecycle change—each one should arrive like a natural product input. Fused makes that path dependable without every team building and then operating its own webhook layer.
Engine verifies the provider signature, handles the challenge, and classifies the event type before anything reaches your application.
Durable queueing, retries, and delivery history happen once in the runtime, instead of being rebuilt slightly differently in every product that consumes an event.
Events are attached to an approved event set and a named SDK application, so a product receives exactly what it subscribed to and nothing else.
