API & Systems Integration
Two systems that both work perfectly can still cost you money every day, if the only thing joining them is a person and a spreadsheet.
Integration work is judged entirely on how it behaves when something goes wrong, because in steady state every approach looks identical. The far end will time out, return a duplicate, or silently change a field type — and what happens next is the whole engagement.
We build integrations that are idempotent, that retry with backoff, that reconcile rather than assume, and that log enough to answer "what happened to this record" months later. Anything less produces the failure mode where nobody notices for six weeks.
Scope
What the work includes.
Written into the scope before anything starts, so there is nothing to discover on the invoice.
Payment and financial rails
Gateway integrations with webhook verification, idempotency keys and reconciliation against settlement reports.
System-to-system synchronisation
Keeping an ERP, CRM, storefront or warehouse system in agreement, with explicit conflict rules rather than last-write-wins.
Public APIs for your own platform
Versioned, documented and authenticated APIs when your partners need to build against you.
Legacy and no-API systems
Database-level, file-drop or scraped integrations where a modern interface simply does not exist, wrapped so the rest of your stack never has to know.
Monitoring and alerting
You find out from a monitor that a feed stopped, not from a customer six weeks later.
Questions
Before you commit.
Usually yes. Options in descending order of preference: an undocumented API their support team can confirm, direct database access, scheduled file exchange, or a robotic process against their interface. Each is progressively more fragile and we will be explicit about which one you are getting and what will eventually break it.
Idempotency keys on every write, so a retried request cannot create a second record, plus reconciliation against the source of truth on a schedule. Retries are guaranteed to happen — networks fail mid-request — so the design assumption is that every call may arrive twice.
Yes. We start with a review of what exists and a written assessment of where it will fail, then either harden it or replace it — whichever is genuinely cheaper. Sometimes the honest answer is that the existing work is fine and only needs monitoring.
