APIs That Push, Not Just Respond in Bradford

“Some products need data the moment it changes — live dashboards, chat and collaboration, presence, order or delivery tracking, instant notifications in Bradford. Request/response REST can't do that well; polling is wasteful and laggy. JW Digital builds realtime APIs over WebSocket and Server-Sent Events with the parts that make them reliable in production: authentication, reconnection, fan-out scaling and backpressure. This is distinct from custom (REST) API development and from event-driven architecture, which orchestrates async work between internal services.”

The Right Tool for Live, Not the Wrong Tool Faster in Bradford

WebSocket/SSE transport built for production scale in Bradford

Teams often try to fake realtime by polling a REST endpoint more aggressively — adding load and latency without ever feeling live. This service builds the correct transport for client-facing live data: persistent connections, authenticated and reconnecting cleanly, scaled to many concurrent clients with backpressure so a slow consumer can't take the system down. Where the realtime need is internal service-to-service async, event-driven architecture is the better fit; for standard CRUD, custom API development.

Live Transport Done Properly

WebSocket or SSE chosen to fit the use case, with authentication, reconnection and message delivery semantics designed for real networks.

Scaled With Backpressure

The bottom line

A realtime API isn't a fast REST API — it's a different system with stateful connections, reconnection logic, ordering and delivery guarantees, and a scaling model where thousands of clients hold open connections at once. Done naively it works in a demo and falls over under real load or flaky mobile networks. in Bradford Built deliberately, realtime becomes a dependable product capability — live collaboration, tracking and notifications that genuinely feel instant — instead of a fragile feature that breaks at scale.

Frequently Asked Questions

Most Asked Questions

FAQs

Common questions about apis that push, not just respond in bradford for businesses in Bradford.

Illustration representing frequently asked questions

REST is request/response — the client asks, the server answers. A realtime API pushes data as it changes over a persistent connection, which is a different system with its own scaling and failure modes.

Related but distinct. Event-driven architecture orchestrates async work between internal services. Realtime APIs deliver live updates to client applications. They often coexist.

It depends on whether you need bidirectional communication and your scale/client constraints. We select during discovery rather than defaulting.

Yes. A realtime layer commonly sits alongside an existing REST backend; we integrate rather than rebuild where that's appropriate.

That's the core of the work — fan-out scaling and backpressure are designed in, then validated with failure-mode testing.
