Third-party APIs, wired in and kept working

Integrating a third-party API means building on ground you do not control. The vendor decides when fields change, how strict the rate limits are, when maintenance windows happen and how long old versions survive. The work is less about making the first call succeed and more about deciding what your system does when the vendor is slow, wrong or offline, and how quickly someone finds out.

Buyers face a few recurring choices. Polling is simple but wastes quota and adds delay; webhooks are faster but need verification and replay handling. A connector platform gets you running quickly but limits custom logic; custom code costs more to build but bends to your process. We also check vendor terms, sandbox quality and pricing tiers, since an API plan can quietly cap your volume.

A good integration keeps working through vendor hiccups, can be paused and replayed, and leaves an audit trail showing exactly what was sent, what came back and when. When a vendor changes something, the integration fails loudly and safely instead of quietly corrupting records, and your team has the runbook, logs and vendor contacts needed to fix it quickly.

Most third-party integrations work in the demo and break months later: a token expires, a vendor renames a field, a webhook arrives twice, a rate limit kicks in during your busiest hour. We build integrations that expect those failures, retry safely, log what happened and alert someone before customers or your finance team notice.

We read the vendor’s documentation closely, test against sandbox accounts, and design the data mapping with the people who use both systems every day, so records land exactly where they belong.
