API integration & interoperability

Your systems already exist. The value is in making them talk.

/ The problem

Most businesses don’t need another system — they need the five they already have to agree with each other. The ERP doesn’t know what the till sold, the bank statement doesn’t match the platform ledger, and someone bridges the gap by retyping numbers.

Point-to-point integrations written as afterthoughts become the most fragile code in the company: no retries, no monitoring, and one person who understands them.

/ How we deliver

We build integrations as first-class systems: explicit contracts on both sides, idempotent operations, dead-letter queues for failures, and dashboards that show what synced, what didn’t, and why. When a nightly sync fails at 3 a.m., the system retries, and if it still fails, a human is told before the business notices.

We have integrated ERPs, banks, telco APIs, logistics providers, and government systems — and where no API exists, we build the adapter, whether that means file drops, database bridges, or structured email parsing.

/ What we build with it

ERP ↔ platform sync

Orders, stock, and invoices flowing both ways on a schedule you can audit.

Bank feeds into your ledger

Statements and confirmations landing in your systems instead of someone’s inbox.

Telco APIs, wrapped once

SMS, USSD, and billing APIs behind one internal interface your team actually likes.

Legacy bridges

That unsupported system nobody dares touch, connected safely without a rewrite.

/ How delivery runs

  1. 1

    Contract mapping

    Both systems’ real data shapes are documented — including the undocumented fields everyone relies on.

  2. 2

    Adapter build

    The integration is built with idempotency, dead-letter queues, and monitoring from the first line.

  3. 3

    Shadow run

    The integration runs alongside the manual process until the numbers match every day.

  4. 4

    Cutover & monitor

    Manual steps switch off, dashboards stay on, and upstream contract tests keep watch.

/ Common questions

Can you integrate with a system that has no API?

Usually, yes — via database-level bridges, scheduled file exchange, or robotic form entry as a last resort. We’ll be honest about the fragility trade-offs of each.

Who maintains the integration afterwards?

Either your team, with runbooks and monitoring we hand over, or ours under a support agreement. Integrations are living systems; we never ship them as fire-and-forget.

How do you handle third-party API changes?

Contract tests against each provider run continuously, so a breaking upstream change is caught by our monitors — not by your operations grinding to a halt.
