In the REST API Documentation under Authentication over HTTPS, the sample code given for ruby is:
require "woocommerce_api"
woocommerce = WooCommerce::API.new(
"https://example.com",
"consumer_key",
"consumer_secret",
{
wp_json: true,
version: "wc/v3"
}
)
When using this sample code, my attempts to access the index with woocommerce.get("") returned -1.
The problem seems to be that this code shows a non-existent wp_json option. The correct name of this option is wp_api.
