Alegor Tech
System Integrations & APIs

Connect your business systems, eliminate manual duplicate work and data silos.

We engineer secure, fault-tolerant, and real-time integrations connecting ERPs, payment gateways, BankID, e-commerce, logistics, and custom APIs. Built with idempotency, async queues, and end-to-end auditability.

Seamless System Harmony

From Fragile Spaghetti APIs to a Robust Integration Hub

As companies scale, software systems are often linked ad-hoc: unmonitored scripts, manual CSV transfers, and fragile webhooks without retry logic. When third-party APIs update, critical business records get silently lost.

Alegor Tech engineers battle-tested integration architecture powered by event queues, automatic retry mechanisms, and data transformation engines. Every payload is validated, logged, and guaranteed for delivery.

How Alegor Integration Engine Operates

Every payload is passed through strict authentication layers, validation, transformation pipelines, and async queues to ensure total reliability.

01. INGESTION Inbound Layer

Sources & Webhooks

Receives events from mobile apps, web storefronts, third-party webhooks, IoT devices, or scheduled pulls.

Webhooks (Klarna, Stripe) 200 OK
Polling Cron / Queue Scheduled
Signature Verification Verified
Engine Core
02. QUEUE & ENGINE Alegor Engine

Transformation & Queues

Payloads are validated and normalized. Idempotency keys prevent duplicate processing. Dead-letter queues catch faulty records.

Idempotency Check Unique
Schema Transformation Normalized
Rate Limiter & Retries Auto Backoff
03. DISPATCH Outbound Layer

Target Systems & Audit

Delivers synced data into ERP, WMS, or analytics databases with 100% audit trail and instant confirmation.

Engineering Excellence

6 Pillars of Integration Reliability & Security

We do not build disposable scripts that fail silently during network hiccups. We engineer enterprise-grade integration pipelines.

Idempotency & Delivery Guarantees

Every incoming event is hashed with a unique idempotency key. Duplicate webhook deliveries from payment gateways are processed exactly once.

Async Queuing & Rate Limit Protection

Third-party APIs enforce strict rate limits. Our queuing layer smoothly throttles requests and gracefully resolves HTTP 429 statuses with exponential backoff.

Security, OAuth2 & Token Lifecycle

Encrypted secret management, certificates, mTLS, and automatic renewal of OAuth2 refresh tokens in dedicated vaults with zero downtime.

Bidirectional Conflict Resolution

When customer records change concurrently across CRM and ERP, deterministic field-level precedence rules ensure clean data harmony.

Dead-Letter Queues & Alerting

If a remote endpoint rejects a payload with a permanent error, it is safely stored in a Dead-Letter Queue with instant Slack or email alert notifications.

GDPR Compliance & Audit Trails

Comprehensive traceability for personal data transfers, automated PII log masking, and built-in support for retention compliance under GDPR.

Zero-downtime deployment with real-time audit logging and instant alert triggers for downstream API outages.

FAQ

Frequently Asked Questions

Common questions regarding API rate limits, security, legacy software, and ongoing maintenance.

We utilize asynchronous queues with exponential backoff retries and Dead-Letter Queues. If a downstream provider experiences downtime, payloads are preserved safely and replayed once the endpoint recovers. Persistent failures trigger automated Slack/email notifications with full request payloads for fast triage.
Yes. We regularly build secure gateway wrappers and data translation layers connecting legacy on-premise databases, SOAP/XML protocols, and SFTP-based batch transfers (CSV/EDIFACT) with modern cloud applications.
We enforce strict idempotency across all pipelines. Each inbound payload is tracked by an Idempotency Key or external event identifier. If a webhook is redelivered, our engine recognizes the completed state and acknowledges the request without re-executing business actions.
All in-flight data is secured using TLS encryption and least-privilege API scopes. Personal data (PII) is automatically redacted from debugging and audit logs. All cloud infrastructure adheres strictly to European GDPR requirements.
Project cost depends on the number of systems, schema complexity, real-time vs. batch sync, and authentication protocols. We offer fixed-price scoping for well-defined integrations (e.g., Fortnox, BankID, Klarna) as well as continuous SLA-backed maintenance and monitoring agreements.
