API and system integration
Stop paying people to move data between systems
The most expensive software in a business is often the person copying figures from one system into another. Integration work removes that, but it fails when it is treated as a script instead of a system: no retries, no idempotency, no visibility, and a silent failure at 2am that nobody notices until month end.
Technologies used
What is included
- Integration map of systems, records and the direction each field flows
- Field-level mapping and transformation rules, agreed in writing
- Idempotent, retrying jobs with dead-letter handling so a failure is recoverable
- A dashboard showing what synced, what failed and why, in business language
- Rate-limit and API-quota handling for third-party services
- Webhook and event handling where the vendor supports it, scheduled polling where they do not
- Runbook for the failures that will eventually happen
How a project like this runs
- 01
Integration audit
Every system, every record type, and who currently retypes what.
- 02
Field mapping
Signed off before build, because most integration disputes are really mapping disputes.
- 03
Build one direction
The highest-volume flow first, running in parallel with the manual process.
- 04
Reconcile
We run both for a period and compare, so you can see the integration is right before you trust it.
- 05
Monitor and hand over
Alerting, the failure dashboard, and a runbook your team can act on.
An illustrative situation, not a client story
An operations team enters every won deal into the CRM, then into accounting, then into a planning spreadsheet. We connect the three: the CRM becomes the source of truth, accounting receives the customer and invoice records, and the planning data is generated rather than typed. Mismatches surface on a review screen instead of in a monthly argument.
Three questions we get about this
There is usually another route: a scheduled export, a database view, a file drop, or automating the vendor UI as a last resort. We tell you which one we are using and how fragile it is.
Versioned integrations, contract tests that fail loudly in CI, and alerting on unexpected payload shapes. You get a warning rather than a silent gap in data.
Yes. A lot of integration value is workflow automation: approvals, document generation, notifications and scheduled reporting.
