Webhook Integration in Belfast

Receiving and sending webhooks reliably for Belfast businesses. Webhooks look trivial — an HTTP request arrives, you process it — and the reason they cause outages is that delivery is at-least-once, unordered, and retried on any response your endpoint fails to return quickly enough.

Why this comes up

The problem

A webhook endpoint exists and occasionally something goes wrong — a duplicate order, a status that arrived out of sequence, or an event nobody can prove was received.

What you get

What we deliver

  • Signature verification, since an unverified endpoint accepts anything anyone sends
  • Idempotent handling, because the same event will be delivered more than once
  • Fast acknowledgement with work queued, so the sender does not time out and retry
  • Out-of-order handling, as events do not arrive in the sequence they occurred
  • Every received event logged, giving you evidence when a partner disputes delivery
  • Outbound webhooks with retries and a dead letter queue where you are the sender

Webhook Integration in Belfast — common questions

Why do we get the same webhook twice?
Because delivery is at-least-once by design — if the sender does not get a prompt success response it retries, including when your processing actually succeeded. Handling must be idempotent; treating duplicates as a bug in the sender is how duplicate orders get created.
Why should we respond before processing?
Senders expect an acknowledgement within a few seconds and retry otherwise. Doing the real work before responding means slow processing triggers retries, which multiplies the load and makes a slow system worse rather than just slow.
Do we need to verify signatures?
Yes. Your endpoint is publicly reachable, so without verification anyone who learns the URL can post events that look genuine. For anything triggering payment, fulfilment or account changes, this is the difference between an integration and an open door.
What if events arrive out of order?
Assume they will — an update can arrive before the creation it depends on. Use the event timestamps and your own state to decide what to apply, rather than trusting arrival order to reflect what happened.
Do you work with businesses across County Antrim?
Yes. We are based in Leicester, United Kingdom and work with clients throughout Northern Ireland, including Belfast and the surrounding County Antrim area. Most collaboration happens remotely, and we travel for kick-offs and key milestones.
What kind of Belfast businesses do you usually work with?

Do you cover the areas around Belfast?
Yes — we work throughout Northern Ireland, including Lisburn, Bangor, Newry. Belfast is an urban area of roughly 345,000+, and we take on work across the wider County Antrim region rather than the city boundary alone.
