API Integration (REST & GraphQL) — Connect Magento to Anything
Secure, reliable and upgrade-safe Magento API integrations: ERP, CRM, WMS, payment & shipping connectors, webhooks, middleware and headless frontends.
Why API Integration Matters
Reliable integrations remove manual work, prevent oversells, accelerate fulfillment and maintain consistent customer experience across platforms.
- Automate order processing & reduce human errors
- Maintain accurate inventory across channels
- Sync financials & reporting in real time
- Support headless frontends with efficient GraphQL
Common Integrations We Build
ERP
SAP, Oracle, Odoo — orders, invoices, stock sync and status updates.
CRM
Salesforce, HubSpot, Zoho — customer data, orders & lifecycle events.
WMS / 3PL
Inventory sync, shipment confirmations and tracking updates.
Payment & Fraud
Gateways, settlement data, fraud checks & reconciliation.
Shipping & Logistics
FedEx, Delhivery, ShipRocket — rates, labels and tracking sync.
Marketplaces
Amazon, eBay — SKU mapping, order import and tracking push.
REST vs GraphQL — Which to Use?
REST
Best for stable third-party APIs, simple resource access, easier caching and broad vendor compatibility.
- Simple CRUD endpoints
- Widespread support
- Easy caching & CDN rules
GraphQL
Best for PWA / headless frontends and complex, tailored payloads — client requests exactly what it needs.
- Reduced payloads
- Fine-grained queries
- Excellent for SSR/SEO PWA frontends
API Integration Services
Strategy & Architecture
Data mapping, sync patterns (real-time / queue / batch), security & SLA planning.
Connector Development
Robust REST/GraphQL connectors with retries, idempotency and rate-limit handling.
Webhooks & Eventing
Secure webhooks, signing, queue integration and DLQs for reliability.
Middleware & Orchestration
Lightweight middleware, transformation, logging and error routing.
Monitoring & Alerts
Dashboards, alerting (Slack/Email), logs and reconciliation tools.
Security & Compliance
OAuth2, HMAC webhooks, JWT, TLS, and PCI guidance for payments.
Typical Integration Patterns
- Order → ERP: Order created → transform → push to ERP → status back to Magento.
- Inventory → WMS: Stock updates from warehouse → update product availability.
- Payments → Accounting: Payment settlement data → push to accounting system.
- Marketplace Connector: SKU mapping → push orders → sync tracking & returns.
- Headless Frontend: GraphQL layer optimized for PWA queries and SSR performance.
Reliability & Resilience
Idempotency
Safe retries without duplicates for orders & payments.
Retry & DLQ
Automatic retries, exponential backoff and dead-letter queues for failed messages.
Audit Trails
Full request/response logs for reconciliation and debugging.
Monitoring
Alerts, metrics and dashboards for integration health.
Example — Verify Webhook Signature
// Node.js example (HMAC SHA256)
const crypto = require('crypto');
function verifyWebhook(rawBody, signature, secret) {
const expected = crypto.createHmac('sha256', secret).update(rawBody).digest('hex');
return crypto.timingSafeEqual(Buffer.from(expected), Buffer.from(signature));
}
We provide secure examples & Postman collections for every connector.
Deliverables
- Production-ready connector(s) with deploy scripts
- OpenAPI (Swagger) or GraphQL schema documentation
- Retry & error handling strategy
- Monitoring & basic reconciliation dashboard
- Postman / Insomnia collections and runbook
- 7–30 days post-launch monitoring (depending on plan)
