Make ERPNext the hub of your entire business
This is where ERPNext becomes powerful. With the REST API, webhooks, OAuth and custom Frappe apps, we connect ERPNext to your mobile apps, portals, marketplaces, payment and logistics providers, BI, AI tools, chatbots and even legacy software, so every system shares one source of truth.
REST API & Webhooks
Seamless real-time data sync and instant event-driven triggers
OAuth2 & Tokens
Robust authentication with scoped permissions and key rotation
Custom Frappe Apps
Upgrade-resilient native integrations built for complex logic
Disconnected systems cost you every day
When your tools do not talk to each other, people become the integration, and people make mistakes.
The integration toolkit
ERPNext runs on the open Frappe framework, which is built for integration from the ground up. These are the tools behind every connection we build.
REST API
Every document type is a REST resource for create, read, update and delete, so any external app can work with ERPNext data over standard HTTP.
Outcome: standard HTTP REST
Webhooks
Fire a payload to any URL on document events such as 'submit' or 'update', with conditions and custom headers, so other systems react in real time.
Outcome: real-time payloads
Custom methods (RPC)
Expose bespoke server functions as endpoints for logic beyond simple CRUD, from validations to complex workflows.
Outcome: server RPC endpoints
OAuth2 and token auth
Secure every call with an API key and secret token or full OAuth2, so external apps and users get scoped, revocable access.
Outcome: scoped credentials
Custom Frappe apps
When off-the-shelf will not do, we build a custom app with server scripts, scheduled jobs, event hooks and background jobs cleanly on the framework.
Outcome: clean framework extension
iPaaS and middleware
Connect through Zapier, Make, n8n or a custom middleware layer when a project needs orchestration across several systems at once.
Outcome: multi-system orchestration
If it has an API, ERPNext can talk to it
The systems below are the ones clients ask for most. The list is not a limit; it is a starting point.
| System | What we connect it for |
|---|---|
| Mobile apps | Custom iOS and Android apps that read and write ERPNext live, for sales, field and warehouse teams. |
| Customer portals | Self-service portals where customers place orders, track status and view invoices, backed by ERPNext. |
| Vendor portals | Supplier portals for purchase orders, delivery updates and payment status, straight from ERPNext. |
| Legacy software | On-premise or older systems bridged to ERPNext through the API or a middleware layer. |
| Internal tools | The spreadsheets, scripts and in-house tools your team relies on are wired into ERPNext data. |
| AI and LLM tools | AI assistants that read ERPNext data to summarise, forecast, draft and answer over the API. |
| Chatbots | WhatsApp, website and internal bots that check stock, place orders and answer queries from ERPNext. |
| ERP to ERP and EDI | Connect ERPNext to another ERP, a group system or an EDI partner for clean data exchange. |
The right pattern for the job
We pick the connection style that fits the use case, not a one-size-fits-all approach.
Real-time API
Systems read and write ERPNext on demand through the REST API.
Event webhooks
ERPNext pushes changes the moment they happen, so nothing polls or waits.
Scheduled sync
Batch jobs sync data on a schedule for volumes that do not need to be instant.
Middleware and iPaaS
An orchestration layer coordinates several systems and transforms data between them.
Custom app
A bespoke Frappe app when the logic belongs inside ERPNext itself.
The API in action
A look at how external systems read and write ERPNext, and how ERPNext pushes events back out. Simplified for clarity.
REST API: read and write over HTTP
Any app authenticates with an API key and secret, then works with ERPNext documents as REST resources. Here a mobile app pulls open sales orders.
Standard HTTP verbs (GET, POST, PUT, DELETE) map to document actions
Secure key and token or OAuth2 authentication ensures safe connections
REST API Request & Response
Illustrative request and response, simplified for clarity.
Real integration stacks we build
These are combinations we implement for clients. Each puts ERPNext at the centre and connects the tools a business actually runs on.
| Blueprint | The stack |
|---|---|
| Full e-commerce stack | Shopify to ERPNext to Razorpay to Shiprocket: shopfront, ERP, payments and shipping in one flow. |
| Website to conversation | From website to ERPNext to WhatsApp plus CRM, capture, manage and follow up without dropping a lead. |
| Attendance to payroll | Biometric to ERPNext to Payroll, from the punch to a paid salary. |
| Multi-marketplace selling | Amazon plus Flipkart to ERPNext, one stock pool across every channel. |
| Live business intelligence | ERPNext to Power BI: dashboards straight from live ERP data. |
| App and self-service | ERPNext, a mobile app plus a customer portal, connects field teams and customers to live data. |
Put an AI assistant on top of ERPNext
Over the same REST API and webhooks, we connect AI and LLM tools and chatbots to ERPNext, so people get answers and actions in plain language, backed by live data.
WhatsApp, web bots, and intelligent forecasting
Bring natural language queries and automated task execution straight to your customer channels and internal portals.
WhatsApp and website bots check stock and place orders instantly
AI assistants summarise sales, receivables and inventory data
Draft quotes and email replies based on real ERPNext records
Every action still respects ERPNext roles and permissions.
AI Chatbot Assistant
Illustrative chat view, not a live ERPNext screenshot.
Secure by design, not as an afterthought
We configure credentials, authorization scopes, and network protection cleanly to keep your ERP secure.
🔐 Scoped access
OAuth2 scopes and API keys give each system only the access it needs, and nothing more.
👥 Role permissions
Every API action still respects ERPNext's own role and permission rules.
🛡️ Encrypted and revocable
Connections run over encrypted links with credentials you can rotate or revoke at any time.
📋 Logged and auditable
Calls and webhook deliveries are logged, so every exchange can be traced.
From idea to a live, monitored integration
We follow a structured deployment model to keep integrations clean, secure and easily upgradeable.
| Step | What happens |
|---|---|
| Discover | We map your systems, data and the flows that matter and agree on the scope. |
| Design | We choose the pattern, define the data mapping and the auth, and plan for failures. |
| Build | We build the connection, custom app or middleware cleanly on the framework. |
| Test | We test edge cases, retries and security before anything touches production. |
| Go live | We deploy with monitoring, then support and extend as you grow. |

Frequently Asked Questions
Common technical and commercial questions about custom ERPNext API integrations.
Almost anything with an API or webhook: mobile apps, customer and vendor portals, legacy and on-premise software, internal tools, AI and LLM tools, chatbots, marketplaces, payment gateways, logistics, banks and BI. ERPNext exposes every document type as a REST resource and supports webhooks, OAuth2, token authentication and custom Frappe apps.
Every ERPNext document type is available as a REST resource for create, read, update and delete, and custom server methods are exposed as endpoints. Calls are authenticated with an API key and secret token or with OAuth2, so external apps read and write ERPNext data securely.
Yes. ERPNext has a native webhook feature that fires on document events such as submit or update and posts a payload to any external URL, with conditions and custom headers, so other systems react in real time without polling.
Yes. Through the REST API and webhooks, ERPNext connects to AI and LLM tools and to chatbots on WhatsApp, websites or internal channels, so a bot can read stock, create orders or answer queries from live ERPNext data, while still respecting roles and permissions.
Usually yes. If the legacy system has any API, file export or database we can reach, we bridge it to ERPNext through the API or middleware layer. Where it has none, we design the most reliable route available and tell you honestly what is involved.
When built correctly, yes. We build using supported extension points such as hooks, custom apps and the API, rather than hacking the core, so integrations keep working through upgrades.
It depends on the systems, the data and the pattern. After a short discovery call we scope the work and give you a clear, fixed quote.
