I have sent request using postman and the python code i provided.But when i send request i do not get header on the server side and receive error like Authorization header with API key missing.

I am not getting my api_key on the server side.

I have tried in local environment. In local, it works fine. But when i have tried in odoo.sh it is not receiving header.

If anyone has any idea on this please help.
