API Integration in Newry
Connecting a Newry business's systems to third-party APIs — payment providers, accounting, CRM, logistics. Integrating against someone else's API means building on something you do not control, so most of the engineering is in handling their outages, their rate limits and their changes rather than their happy path.
Why this comes up
The problem
Two systems need to share data and currently a person exports from one and imports into the other. It happens late, sometimes twice, and occasionally not at all.
What you get
What we deliver
- Authentication handled properly, including token refresh before expiry rather than after failure
- Retries with backoff, since rate limits and transient errors are routine
- Idempotency, so a retried request does not create a duplicate order or payment
- Webhooks consumed where offered, replacing polling that is slow and wasteful
- Failure surfaced to someone, rather than logged where nobody looks
- Monitoring of the third party's availability, so their outage is not diagnosed as your bug

API Integration in Newry — common questions
- What breaks integrations most often?
- Credential expiry, rate limits, and the third party changing something without warning you. None are exotic — they are the normal operating conditions of building on someone else's API, and an integration that assumes otherwise fails routinely.
- Why does idempotency matter?
- Because retries happen. If a request times out after the other side processed it, retrying without an idempotency key creates a second order, payment or invoice. Most serious APIs support keys; using them is the difference between a safe retry and a duplicate.
- Webhooks or polling?
- Webhooks where available — faster and far less wasteful. They need a public endpoint, signature verification and tolerance for duplicate deliveries. Polling remains the fallback where no webhook exists or delivery cannot be relied upon.
- What happens when their API goes down?
- Your integration should queue and retry rather than lose data, and someone should be told. The common failure is silent — the integration stops, nobody notices for two days, and the backlog is discovered by a customer.
- Do you work with businesses across County Down?
- Yes. We are based in Leicester, United Kingdom and work with clients throughout Northern Ireland, including Newry and the surrounding County Down area. Most collaboration happens remotely, and we travel for kick-offs and key milestones.
- What kind of Newry businesses do you usually work with?
- Dual-currency retail and haulage systems handling cross-border VAT, customs paperwork and two pricing structures. Beyond that we work across Retail, Logistics, Manufacturing, Construction and Food Production.
- Do you cover the areas around Newry?
- Yes — we work throughout Northern Ireland, including Belfast, Lisburn. Newry is an urban area of roughly 27,000+, and we take on work across the wider County Down region rather than the city boundary alone.
