Wialon Integration Services

Most Wialon integrations are not hard to build. They are hard to keep running. The first version pulls units and trips on a timer, writes them into the target system, and works for a month. Then the token expires overnight, an ERP release renames a field, a driver swaps a unit between groups, and the export goes quiet — usually discovered at month-end close rather than by an alert.

We design for those failure modes first, because they are the ones that cost money. Every job is idempotent, so a replay after an outage does not double-count a trip. Every sync writes a run record with counts and a status, so "it worked" is a fact you can query rather than an assumption. And every integration ships with a reconciliation check that compares what Wialon holds against what landed downstream, on a schedule, and raises an alert on drift before finance does.

The pattern is nearly always the same: telematics knows where and how a vehicle ran, the business system knows what that run was worth, and nobody can answer a question that needs both. What differs is which side owns each field and how fast the answer is needed.

Asking for everything in real time is the fastest way to a fragile, expensive integration. Order status genuinely needs to move within seconds — a dispatcher acting on a ten-minute-old position is acting on fiction. Monthly mileage for invoicing does not: an overnight batch is cheaper to run, easier to reason about, and recovers from an outage on its own by catching up the next night.

We split every field into three classes before writing code — real time, near real time, and batch — and price them separately. In practice that conversation removes half the real-time requirements in the first workshop, and the remaining half become genuinely reliable because they are not competing with bulk report pulls for the same API budget.

The deployed integration, its source code, and the documentation needed to run it without us. That includes the data contract with field-level ownership, runbooks for the failures that actually occur, dashboards for sync status and lag, and the alert routing that tells a named person when a run does not complete.

If your team wants to take over maintenance, that is the intended outcome rather than an exception. If you would rather we stay on, that is a support agreement with a defined scope — not a dependency created by withholding the code. Teams that already have an integration behaving badly usually start with a technical review instead, and we scope the fix from what that finds.
