Override Woocommerce REST api per_page limit to increase the maximum number of products per page

Large queries can hurt site performance, Woocommerce set the default per_page REST parameter at 100 records. Therefore, if you request something higher than 100 you will get this error:

   {
        "code": "rest_invalid_param",
        "message": "Invalid parameter(s): per_page",
        "data": {
            "status": 400,
            "params": {
                "per_page": "per_page must be between 1 (inclusive) and 100 (inclusive)"
            }
        }
    }
