Hi everyone,

We are running an online shop that uses Odoo purely as a backend via its API. Our goal is to handle as much as possible through Odoo, including shopping carts, checkout, login, and payment.

Everything works fine for logged-in users. For anonymous users(not logged-in users), we can retrieve all draft orders (shopping carts) through the API. However, the challenge is matching a specific cart to a specific anonymous user, for example by the browser session_id.

Currently, all anonymous carts are linked to the public user (ID 4). My assumption is that Odoo tracks them via the session_id, but I haven’t been able to find a way to associate the session or any client-side identifier with a cart via the API.

Does anyone know the recommended way to retrieve the correct cart for a specific anonymous user using Odoo’s API? Is there a standard approach for linking carts to sessions for public users? Is it even possible?

Thanks in advance for any guidance!

Odoo's XML-RPC/JSON-RPC API does not expose session_id for anonymous cart tracking - sessions are handled server-side via HTTP cookies and not accessible through the standard API. Here are the recommended approaches:

Use the sale.order access_token: Each sale.order has an access_token field. When creating an anonymous cart via API, read and store this token client-side (cookie/localStorage). Use it to filter/retrieve the specific cart: search sale.order where access_token = your_stored_token.

2. Use Odoo HTTP controllers instead of XML-RPC: Make HTTP requests with session cookies to Odoo website endpoints (/shop/cart/update, /web/dataset/call_kw). This preserves the server session and handles anonymous cart linking natively.

3. Custom client identifier field: Add a custom field (e.g., client_uuid) to sale.order via Studio. Generate a UUID client-side, send it when creating a cart, and use it to retrieve the cart later. This is the cleanest pure-API approach.
