ServiceWeb Challengers

Integrations that hold upin production.

APIs, webhooks and system connections engineered for the parts integrations usually miss — authentication, retries, duplicate events, reconciliation and the visibility to debug them.

In plain terms

The demo is easy. Tuesday month is the test.

Every integration works in the demo. The real test is the Tuesday when a provider has an outage, a webhook fires twice, or an order arrives malformed. We build for that Tuesday: idempotent handlers, dead-letter queues, retries with backoff and alerting that tells a human before a customer does.

We begin with ownership, not endpoints: which system is the source of truth for each record, what happens on conflict, and what staff see when a connection drops. Those decisions — made before any code — are the difference between an integration and a liability.

Then we make it observable. Every connection logs what it sent, what came back and what it did about it, with a small admin screen so support can answer 'did that order go through?' without waking a developer.

  1. 01

    Source-of-truth and conflict rules agreed before build

  2. 02

    Retries, idempotency and failure queues as standard

  3. 03

    Monitoring with alerts that reach a human early

  4. 04

    Credentials and access structured for long-term ownership

What we deliver

Connections you can forget about.

Scoped per system — one clean payment connection or a whole operational ecosystem.

01

API design & build

REST APIs with versioning, authentication and documentation your own team can build against confidently.

02

Third-party integrations

Payments, CRM, ERP, shipping, marketing and finance systems connected with their quirks handled and documented.

03

Webhooks & event processing

Inbound events verified, deduplicated and queued — so a provider's retry storm never corrupts your data.

04

Data synchronisation

Record-level sync between platforms with conflict rules, so both systems agree on what is true.

05

Legacy system bridges

Clean APIs laid over ageing software that was never designed to talk to anything — without touching its core.

06

Integration monitoring & ops

Dashboards, alerting and an admin view of every event — with reconciliation reports for finance.

How we work

Map it, build it, break it, watch it.

We test failure on purpose before production finds it for us.

  1. Map the data

    Systems, record ownership, volumes and failure consequences documented and agreed before any endpoint is touched.

  2. Build the happy path

    Core connection delivered first, with real credentials and realistic data volumes from day one.

  3. Break it deliberately

    Timeouts, duplicates, malformed payloads and provider outages simulated — then handled for real.

  4. Monitor & hand over

    Alerts, dashboards and runbooks in place, with your team trained on the admin screens.

Before you start

Two questions that surface the real scope.

01 · Data

Who owns the truth when two systems disagree?

Most integration pain is a data-ownership question wearing a technical costume. If your CRM and your billing system both believe they hold the customer's email, one of them will eventually win — decide which, and when, before the first sync runs.

  • Name the master system for each record type
  • Decide what happens on conflicting updates
  • Agree the volume and frequency of movement
  • Know what a provider outage is allowed to stop
02 · Providers

Check the boring constraints first

Rate limits, webhook timeouts, sandbox quirks and API version deprecations decide timelines more than code does. We read provider documentation so you don't have to — and flag the constraints that will shape your roadmap.

  • Rate limits against your real volumes
  • Sandbox versus production behaviour differences
  • Deprecation schedules for versioned APIs
  • Contractual support quality of each provider
FAQ

Questions clients usually ask.

Straight answers about how this work is scoped, delivered and supported.

Ask something else
01Can you integrate with our old system that has no API?

Usually. We bridge via database views, file exchange or a thin API layer over the legacy system — clean integration without destabilising what already works.

02What happens when a provider goes down?

Events queue with retries and alerts. Nothing is lost, staff see a clear status, and the backlog processes itself when the provider recovers.

03Can you fix an integration someone else built?

Yes — we trace the failure modes, add the missing reliability layer (retries, logging, reconciliation) and stabilise it, whether or not a rewrite is needed.

04How do you keep credentials safe?

Secrets live in a vault or environment store, never in code — with least-privilege access per connection and rotation handled as routine.

Start with a conversation

Need two systems to finally cooperate?

Tell us what needs to talk to what, and what breaks when it doesn't. We will scope the connection — including the failure paths nobody else quotes for.
