Reading this model through the API

Odoo 19 JSON-2 API call reading the first five records with real fields of the model. Replace the instance, database and API key with your own.

curl

curl -X POST "https://your-instance.odoo.com/json/2/product.uom/search_read" \
  -H "Authorization: bearer $ODOO_API_KEY" \
  -H "X-Odoo-Database: your-db" \
  -H "Content-Type: application/json" \
  -d '{"domain":[],"fields":["barcode","product_id","uom_id","company_id"],"limit":5}'

Python (requests)

import requests

BASE_URL = "https://your-instance.odoo.com/json/2"
headers = {"Authorization": f"bearer {API_KEY}", "X-Odoo-Database": "your-db"}

res = requests.post(
    f"{BASE_URL}/product.uom/search_read",
    headers=headers,
    json={"domain": [], "fields": ["barcode","product_id","uom_id","company_id"], "limit": 5},
)
res.raise_for_status()
print(res.json())

External API access requires Odoo's Custom plan.
XML-RPC and JSON-RPC will be removed in Odoo 22 (fall 2028): use JSON-2.
The access rights and record rules of the key's user apply.
