Hello, 

Yes, this is definitely possible in Odoo.

Odoo supports integration with third-party applications through REST APIs. The typical approach is to connect the external system with Odoo and map the required data (such as customers, products, sales orders, and invoices) so records can be created, updated, or synchronized automatically.

The exact implementation depends on:

• Which third-party application you are integrating with
• Whether the data flow is one-way or two-way
• The API specifications and authentication method provided by the external system

If you can share more details about the third-party platform and your integration requirements, we can suggest the most suitable approach.

Hope this works for you! If you need any help implementing this or want a more optimized approach, feel free to reach out for further discussion.

Hi Willion,

Welcome to the Odoo community!

Integrating third-party invoices and sales orders with Odoo through REST APIs is a common requirement and can be implemented in several ways depending on the external system.

A typical integration flow would be:

1. Analyze the Third-Party API

   • Review the API documentation.

   • Identify authentication methods (API Key, OAuth, Bearer Token, etc.).

   • Understand the request/response formats (usually JSON).

2. Create a Custom Odoo Module

   • Develop a custom module to handle the integration logic.

   • Use Python libraries such as requests to communicate with the external API.

3. Map External Data to Odoo Models

   • Sales Orders → sale.order

   • Invoices → account.move

   • Customers → res.partner

   • Products → product.product

4. Implement Synchronization

   • Import data from the external system into Odoo.

   • Optionally export Odoo records back to the external system.

   • Use scheduled actions (Cron Jobs) for automatic synchronization.

5. Handle Errors and Logging

   • Store API responses and errors for troubleshooting.

   • Implement retry mechanisms for failed requests.

Example (REST API call from Odoo):

import requests

response = requests.get(
    "https://api.example.com/orders",
    headers={"Authorization": "Bearer YOUR_TOKEN"}
)

data = response.json()

If you can share:

• Your Odoo version

• The third-party system name

• Whether the integration is one-way or two-way

the community can provide more specific guidance and examples.

Hi,

Yes, this is definitely achievable! Here's the general approach for syncing third-party invoices and sales orders into Odoo via REST API:

1. Authenticate first:

import requests

session = requests.Session()
response = session.post('https://your-odoo.com/web/dataset/call_kw', json={
    "jsonrpc": "2.0",
    "method": "call",
    "params": {
        "model": "res.users",
        "method": "authenticate",
        "args": ["your-db", "admin@example.com", "password", {}],
        "kwargs": {}
    }
})
uid = response.json().get("result")

2. Create a Sales Order (sale.order):

session.post('https://your-odoo.com/web/dataset/call_kw', json={
    "jsonrpc": "2.0",
    "method": "call",
    "params": {
        "model": "sale.order",
        "method": "create",
        "args": [{"partner_id": 1, "order_line": [(0, 0, {
            "product_id": 5,
            "product_uom_qty": 2,
            "price_unit": 100.0
        })]}],
        "kwargs": {}
    }
})

3. Create an Invoice (account.move):

session.post('https://your-odoo.com/web/dataset/call_kw', json={
    "jsonrpc": "2.0",
    "method": "call",
    "params": {
        "model": "account.move",
        "method": "create",
        "args": [{"move_type": "out_invoice", "partner_id": 1, "invoice_line_ids": [(0, 0, {
            "name": "Service",
            "quantity": 1,
            "price_unit": 200.0
        })]}],
        "kwargs": {}
    }
})

For duplicate prevention, always search for an existing record before creating:

# Check if order already exists by external reference
session.post('...call_kw', json={
    "params": {
        "model": "sale.order",
        "method": "search_read",
        "args": [[["client_order_ref", "=", "EXT-ORDER-123"]]],
        "kwargs": {"fields": ["id"], "limit": 1}
    }
})

If you want to avoid the JSON-RPC boilerplate and work with a cleaner REST interface, REST API Toolkit (available on the Odoo App Store for Odoo 19) lets you do all of this with simple GET/POST/PATCH/DELETE endpoints and Bearer token auth — much easier to integrate with third-party platforms.

Hope that helps!

Hi Willion,

Yes, this is possible using Odoo REST/XML-RPC APIs or custom API endpoints depending on your Odoo version and integration requirements.

For your use case, the process usually involves:

• Authenticating with the Odoo API

• Mapping third-party invoice and sales order data

• Creating/updating records in Odoo (sale.order and account.move)

• Handling customer/product synchronization

• Managing error handling and duplicate prevention

The best approach depends on:

• your Odoo version,

• the third-party system you want to connect,

• and whether the sync should be real-time or scheduled.

If you can share a few more details about the external platform/API you are integrating with, I can guide you more specifically.
