Frame the problem
API design / Webhooks
QUANTEX
API integration & automation engineering
Connect systems without creating invisible failure points.
An integration is an ongoing agreement between systems that change independently. We document payloads, ownership, authentication and retry behavior before connecting production data. Queueing, idempotency and reconciliation make failures recoverable, while monitoring distinguishes a delayed event from a lost one.

A delivery model built around the task
Build the proof
Provider integrations / Event queues
Validate the release
Versioned contracts, mappings and test fixtures with a runbook for failed or duplicated events.
The constellation
Map the decisions, people and information that shape the experience.
API designThe connection
Give every hand-off a clear contract, owner and recovery path.
WebhooksThe launch
Test the complete journey before it becomes everyday operation.
Provider integrationsWhat you take away
Versioned contracts, mappings and test fixtures with a runbook for failed or duplicated events.
A question worth asking
What happens when a provider changes its API?
We track version dependencies and isolate adapters. Deprecation handling and ongoing maintenance are scoped explicitly rather than assumed to be permanent compatibility.
