API Development & Integration
Connect the systems your business already depends on.
Overview
Businesses rarely have a data problem; they have a data movement problem. Orders live in one system, customers in another, invoices in a third, and people re-key information between them.
Markedge designs and builds the integration layer: APIs that expose your data safely, connectors that synchronise systems, and middleware that handles retries, mapping and monitoring so integrations keep working when something on either side changes.
We also build public and partner APIs for businesses that need customers or partners to connect to their platform.
Benefits
Enter data once
Records flow between systems automatically, removing re-keying and reconciliation.
Resilient by design
Retries, idempotency, monitoring and alerting mean failures are visible and recoverable, not silent.
Future-proof
Versioned, documented APIs let you replace a system without rewriting every integration.
What we deliver
API design
REST and event-based APIs with authentication, versioning and documentation.
System integration
Connectors between CRM, ERP, accounting, e-commerce, HR and messaging platforms.
Middleware and queues
Reliable message handling, transformation, scheduling and error queues.
Monitoring
Dashboards and alerts for volumes, failures and latency.
How we work
-
Step 1: Map the data flows
Which systems own which data, in which direction it moves and how conflicts are resolved.
-
Step 2: Design contracts
API specifications, mappings, authentication and failure handling agreed up front.
-
Step 3: Build and test
Implement with contract tests and sandbox environments on both sides.
-
Step 4: Operate
Deploy with monitoring, runbooks and a support path.

Frequently asked questions
We assess the available options such as exports, database access or file exchange and design the most reliable path, being clear about any limitations.
Every integration is built with retries, dead-letter handling and alerts, plus a runbook that explains how to re-process failed records.
Yes. Public and partner APIs include authentication, rate limiting, versioning and documentation.
