Odoo integration
Integrate Odoo with eCommerce platforms, payment gateways, CRMs, logistics providers, marketplaces, mobile applications and custom systems, with the error handling and monitoring that keep integrations working after launch.

Businesses that run on what we built
Why integrate
Odoo integration connects Odoo to the systems a business already runs (storefronts, payment providers, CRMs, shipping, communication and custom or mobile applications) so data flows automatically instead of being re-keyed. It's usually cheaper and less disruptive than replacing working systems, and it lets Odoo be the system of record without being the only system.
The value of an integration is entirely in its reliability. A synchronization that silently drops one order in a thousand is worse than no integration, because nobody is watching the gap. That is why we treat integration as an engineering discipline (retries, idempotency, logging, reconciliation) rather than a connector to be configured.
Systems
Categories we have delivered in production. Named systems are ones we have actually connected.
Headless storefronts (Next.js), Odoo eCommerce, custom shops. Products, stock, prices, orders and customers kept in sync.
Razorpay subscriptions, Cashfree, Stripe, Paytm POS EDC terminals: online checkout, recurring billing and counter payments posted straight into Odoo.
Zoho CRM and Books, Monday.com, Calendly: leads, contacts and events flowing both ways.
Shiprocket shipping rates and fulfilment, barcode and RFID scanners, direct-to-printer labels and receipts.
MSG91 SMS and OTP, Twilio, Firebase Cloud Messaging push, Outlook IMAP, SMTP: notifications and authentication.
Swedbank API for statements and payments, multi-currency gateways, reconciliation flows.
React Native and Flutter apps for customers, suppliers and members, on GraphQL and REST APIs we build.
Member portals, real-time messaging servers, search engines (Meilisearch), object storage (S3, Cloudflare R2) and automation platforms (Zapier).
Integration guides
Each of these has its own page: which system owns which data, the lifecycle, how it fails and the project it comes from. A platform appears here once we have run it in production.
Two-way sync of products, customers, orders, inventory and fulfilment.
Checkout, recurring billing, refunds and reconciliation on webhook-driven flows.
Indian online payments and automated recurring billing tied to the Odoo ledger.
Checkout and payment status inside an Odoo order flow, confirmed once.
Approved templates, order notifications and replies that land on the customer record.
Shipping rates at checkout, fulfilment hand-off and status back into Odoo.
Statements, reconciliation and approved payment workflows, with an audit trail.
Integration methods
The right method depends on direction, volume, latency and who owns the other side.
| Method | Best for | Watch out for |
|---|---|---|
| REST API | Request/response from external apps, simple, well-understood contracts | Over-fetching on mobile, versioning as models change |
| GraphQL | Web and mobile clients needing shaped, fast reads, storefronts and apps | Query cost limits, caching strategy |
| Webhooks | Real-time events from payment providers, storefronts, SaaS tools | Signature validation, retries, duplicate deliveries |
| Scheduled jobs | Batch sync with systems that have no events, nightly reconciliation | Window size, overlap, failure visibility |
| Queues | High-volume or bursty traffic, decoupling Odoo from slow third parties | Ordering, dead-letter handling, monitoring |
| Direct database | Read-only reporting in a controlled environment | Bypasses business logic and security: avoid for writes |
| Third-party APIs | Payments, SMS, shipping, banking | Rate limits, sandbox vs production, credential rotation |
Direct database integration is tempting and usually wrong: it skips Odoo's ORM, validation, access rules and audit trail. We use it only for controlled read-only reporting, never for writes.
Architecture
External systems talk to an integration layer (APIs, webhooks, queues) which talks to Odoo through its ORM. Business rules stay in one place. Failures are visible in one place.
Storefront + mobile
Next.js shop, React Native / Flutter apps
Payments + logistics
Razorpay, Cashfree, Stripe, Paytm EDC, Shiprocket
CRM + SaaS
Zoho, Monday.com, Calendly, Zapier, banking
API and queue layer
GraphQL · REST · Webhooks · scheduled jobs · queues: validation, retries, idempotency, logging
Odoo
The system of record: orders, customers, stock, invoices, subscriptions
PostgreSQL + services
Redis for queues and cache, Meilisearch for search, S3/R2 for files
Reliability
These are the properties we design in. They're the difference between an integration and a liability.
Transient failures (a payment API timeout, a storefront hiccup) are retried automatically, not lost.
A retried or duplicated webhook creates one order, not two. Every write carries a key that makes it safe to repeat.
Bursts (a sale, a catalogue import) are absorbed by a queue instead of taking Odoo down.
Every message in and out is logged with status. Failures raise alerts. They don't wait to be noticed.
Scheduled comparison of both sides (orders, payments, stock) so drift is found and fixed, not discovered by a customer.
Webhook signatures verified, rate limits respected, credentials rotated, sandbox and production kept apart.
Evidence
Payment, mobile, eCommerce, GraphQL, CRM and custom APIs, connected to Odoo and still running.
Jewellery retail & manufacturing
Multi-store fine jewellery retail and manufacturing on Odoo Enterprise: daily metal rates, RFID-tagged serialized stock, gold saving schemes with recurring payments, and a customer mobile app synced over GraphQL.
eCommerce, baby care
A direct-to-consumer baby care brand selling through a Next.js storefront, with Odoo behind it for ERP, inventory, orders and customers: connected over GraphQL, with Cashfree payments, Shiprocket shipping and a distributor onboarding portal.
SaaS: digital business cards
Digital profile and contact-sharing platform where Odoo runs subscriptions, orders and the store behind a web frontend and a Flutter mobile app, with Stripe recurring payments, Google integrations and vCard export.
ERP consulting (Odoo partner)
Heliconia developers working as an extension of another Odoo partner’s engineering department: multiple client migrations from Odoo 17 to 18 Enterprise, custom module upgrades, Odoo.sh operations, and Monday.com, Calendly and Zapier integrations.
First-party experience
Payment webhooks arrive twice. Idempotency isn't a nice-to-have. It's the difference between one invoice and two.
A GraphQL layer built for a mobile app becomes the storefront API, the supplier portal API and the reporting API. Design it as a product.
Counter hardware (EDC terminals, label printers, RFID scanners) needs a fallback path for when it's offline, decided before go-live.
Reconciliation jobs find the bugs that logs don't: a sync that succeeds but writes the wrong quantity.

Kartson KrayChairman, TIMmunity GmbHQuestions
Yes. Odoo can synchronize products, stock, prices, orders and customers with Shopify through the Shopify API and webhooks, with Odoo as the system of record for stock and fulfilment.
Our storefront work to date has been on headless Next.js shops connected to Odoo over GraphQL. The same integration layer applies to Shopify.
Yes. Custom applications connect through REST or GraphQL APIs we build on Odoo, or through webhooks and queues for event-driven flows, as with Freiburger Bund's member portal and real-time messaging server.
Yes. Odoo exposes XML-RPC and JSON-RPC APIs to every model out of the box. For production integrations we usually add purpose-built REST or GraphQL endpoints with proper authentication, shaped payloads and rate limits.
Yes. REST controllers and GraphQL schemas exposing exactly the models and operations a client needs, documented and versioned.
Yes. We build the mobile app and the API together, React Native or Flutter on GraphQL/REST, for customer apps (Aria Jewellers), supplier apps (Ramdev Kangan) and member apps (Freiburger Bund).
Yes. Online gateways (Razorpay, Cashfree, Stripe), recurring subscriptions and physical POS terminals (Paytm EDC) are integrated so payments post to the right invoice or order automatically.
Failures are retried with backoff, logged with the full payload, and surfaced as alerts. Scheduled reconciliation compares both systems so anything that slipped through is found and corrected.
Yes. Webhooks and event queues give near-real-time flows. For genuinely real-time features (chat, presence, live updates) we run a dedicated Socket.IO service authenticated against Odoo, as at Freiburger Bund.
