Two systems holding different versions of the same customer is an operating cost, not a technical footnote. Zylax builds the integrations that keep records aligned across your platforms, along with the monitoring that tells you the moment they stop agreeing.
API Integration & Data Sync
What we deliver
- REST and webhook integrations between platforms
- CRM, accounting and e-commerce connections
- Payment gateway and logistics carrier links
- Scheduled batch and real-time event synchronisation
- Field mapping, transformation and validation rules
- Idempotency keys and controlled retry handling
- Failure alerting with reconciliation reports
- One-off migrations and historical data loads
Ideal for: Teams re-entering the same order, invoice or contact into a second system, or comparing two exports by hand every week.
Why teams choose Zylax
Integrations are judged on the bad days. Ours are designed around what happens when an endpoint times out, a payload changes shape or the same record arrives twice.
Contracts Before Code
Field mappings, mandatory values and rejection rules are documented and agreed, so nobody argues about expected behaviour later.
Safe To Replay
Every write is keyed, so a retry cannot produce a duplicate order, payment or contact record.
Failures Stay Visible
Errors raise an alert carrying the payload, the reason and the affected record, instead of settling into a log nobody opens.
Reconciliation Included
Scheduled comparison reports confirm both systems still agree on counts and totals, and list the rows that do not.
How we work
From first conversation to long after launch.
We turn an unclear requirement into a practical plan — clarifying users, workflows, data, integrations and success criteria before development begins.
Discover & define
We agree what success looks like before writing any code.
- Objectives and users clarified
- Scope and acceptance criteria
- Architecture and delivery stages
- Clear, fixed quotation
Design & build
Delivered in reviewable stages, tested as we go.
- Interface and user journeys
- Development in reviewable stages
- Integrations and data handling
- Continuous testing and QA
Launch & improve
A controlled release, then we stay accountable.
- Controlled deployment
- Handover and documentation
- Post-launch support
- Maintenance and future phases
Scope & next step
Integration effort follows the number of endpoints, the state of the source data and how quickly records must move, so we scope before quoting anything. Tell us which two systems disagree and how often, and we will map the work.

How will we know a sync has failed?
One of our vendors has no API. Can you still connect it?
Do you handle the first data load as well?
