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.

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}/base.language.install/search_read",
    headers=headers,
    json={"domain": [], "fields": ["overwrite"], "limit": 5},
)
res.raise_for_status()

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.
