Woocommerce REST API?

Hello @thibotus01

Thank you for your question.

The plugin does not include any functions impacting the standard WooCommerce REST API.
As I look through the REST API documentation, there is no easy way to find a specific note by searching for words from its content.

You have to know the particular note ID and order ID to retrieve it using API.
