Integrations
Connect external platforms and internal systems without making your team the adapter between them.
The operational problem
The difficult part of an integration is preserving correct state when providers disagree, fail, delay events or behave differently from the example in their documentation.
Signs the current system has reached its limit
- Provider events arrive duplicated, late or out of order.
- A successful acknowledgment is treated as proof that business work completed.
- People reconcile records manually after an outage.
- Provider-specific states have leaked into every internal workflow.
Why ordinary implementations fail
- There is no idempotency or replay path.
- Provider behaviour is assumed to match its documentation.
- Retries run forever on permanent failures.
- No reconciliation compares internal state with the external source of truth.
Representative system flow
Make the abnormal path visible.
This is a reference shape, not a claim about a completed client project. The important detail is the control around the normal path.
What gets built
Adapter layer and domain translation
Webhook validation and idempotency
State mapping and durable event processing
Retry policy and dead-letter handling
Reconciliation jobs and discrepancy views
Monitoring, diagnostics and operator replay
Deliberate exclusions
- Connecting systems without agreeing which one owns each fact
- Treating a provider’s native integration as reliable without testing its failure behaviour
- Building a new dependency without an owner for operating it
Evidence / precisely labelled
Production work completed as an employee: insurance API integrations and the production system around provider inconsistencies. Not an Absolyd client engagement.
Safest first engagement
Integration inventory, source-of-truth analysis and failure-mode review before implementation scope is proposed.
The Operational System Review is a paid, bounded investigation. It can lead into implementation, but it does not obligate you to continue. You retain the written findings.
Questions buyers usually ask
Do you only work with APIs?
No. The boundary may include webhooks, files, scheduled imports or other provider mechanisms. The design follows the guarantees the system actually has.
What happens when two systems disagree?
The disagreement becomes visible, attributable and actionable through state mapping, reconciliation and an operator recovery path.

Operational System Review
A responsible first phase for a manual, fragile or unclear operational system. The review makes the current boundary, failure modes and safest first production scope visible before implementation begins.
