Integrations & API Connectors — connect ERPNext to the systems you already run

Build reliable, audited and maintainable integrations — e-commerce platforms, marketplaces, payment gateways, shipping carriers, BI systems and custom APIs. Focus on business logic; we handle reliability, scale and security.

Why robust integrations matter

Bad integrations cause data drift, duplicate work and operational risk. We deliver connectors that are observable, retry-safe, idempotent and easy to maintain — minimizing manual reconciliation and improving SLA adherence.

Connected data

Single source of truth with automated syncs for orders, payments, stock, customers and shipments.

Faster fulfillment

Real-time shipping updates and inventory level syncing to avoid oversells and speed delivery.

Secure & auditable

Encrypted credentials, audit logs, retry queues and monitoring to satisfy auditors and ops teams.

Integration services we provide

From one-off connectors to managed integration platforms and long-term support contracts.

E-commerce & Marketplaces

Connect storefronts (Shopify, WooCommerce, Magento) and marketplaces (Amazon, Flipkart) to ERPNext — orders, inventory, pricing and shipping sync.

  • Two-way inventory & order sync
  • Automated pricing rules & mapping
  • Return/Refund workflows

Payments & Gateways

Integrate payment gateways (Razorpay, PayU, Stripe) for reconciled payments, settlement monitoring and webhooks.

  • Webhook handling with idempotency
  • Settlement & fee reconciliation
  • Chargeback & refund workflows

Shipping & Logistics

Connect carriers (Delhivery, Shiprocket, FedEx) for rates, label printing, tracking and POD capture.

  • Rate lookup & auto-selection
  • Label generation & manifesting
  • Tracking & delivery confirmations

Accounting / Banking

Bank statement ingestion, payment matching and automatic reconciliation into ERPNext ledgers.

CRM & Marketing Tools

Sync customers, leads, activities and campaign attribution between CRM (HubSpot, Zoho CRM) and ERPNext.

BI & Data Warehousing

Export to BI tools or data warehouses (Metabase, PowerBI, BigQuery) for analytics and dashboards using incremental pipelines.

Custom Systems & IoT

Integrations for factory scanners, barcode systems, and bespoke applications — real-time or batched as required.

Third-party APIs

Payment processors, KYC providers, tax APIs (GST), shipping, and other external services integrated securely.

Integration patterns & architecture

We choose patterns based on SLA, scale and existing infra.

1. Webhook-driven real-time

Use when external systems can push events (orders, payments). Webhooks handled by an idempotent endpoint, validated, queued and processed into ERPNext. Supports near real-time user experience and instant reconciliation.

  • Idempotent handlers
  • Immediate validation & quick ACK responses
  • Long-running tasks queued for heavy transforms

2. Polling / Scheduled sync

Best for systems that don't support webhooks. Polling services run at scheduled intervals, perform deltas, and apply safe retries.

3. Event-driven pipeline (message bus)

For high-scale environments we use a durable message bus (Kafka/RabbitMQ) to decouple systems — supports replay, backpressure and complex orchestrations.

4. Middleware & Transform layer

A middleware service performs mapping, enrichment, id mapping (SKUs/customers), and can expose a stable contract to ERPNext while absorbing changes from external systems.

Delivery, testing & reliability

We follow engineering best practices to reduce incidents and make integrations maintenance-friendly.

Testing

  • Contract tests for APIs
  • Integration tests with staging webhooks
  • End-to-end reconciliation tests

Reliability

  • Retry queues with exponential backoff
  • Dead-letter queues and alerting for manual review
  • Automatic duplicate detection & idempotency

Observability

  • Structured logs & correlation IDs
  • Metrics (success rate, latency, backlog size)
  • Dashboards and paging policies

Security

  • Encrypted credentials (vaults)
  • Least-privilege API keys & scoped tokens
  • Signed webhooks, request validation and rate limits

Sample connectors we've built

Real examples — what we deliver in a typical connector package.

Shopify ↔ ERPNext

Order import, inventory sync, product & variant mapping, refunds and fulfillment updates.

Razorpay ↔ ERPNext

Webhook-driven payment capture, settlement reconciliation and fee accounting into ledgers.

Shiprocket / Delhivery ↔ ERPNext

Rate lookup, label printing, tracking ingest and delivery confirmation mapped to sales orders.

Engagement styles

We offer: fixed-price connector delivery, sprint-based integration projects, or managed integration platform support. For accurate estimates we assess API complexity, expected throughput and SLAs.

Frequently asked questions

How long does a connector take to build?
Simple connectors (1 API, clear docs) can be delivered in 1–2 weeks. Complex integrations (many transforms, reliability, high throughput) typically take 3–8 weeks depending on testing and edge cases.
Do you provide monitoring after delivery?
Yes — we offer managed monitoring, alerting and support packages to keep integrations healthy and respond quickly to incidents.
What about API rate limits and throttling?
We implement exponential backoff, token rotation, and distributed rate limiting in middleware. If the partner API has strict limits, we design batching strategies and caching.
