    Salve, sono un'infermiere e vorrei far creare un software per permettere di collegare tutta la lista pazienti, a questo software, per tenere il conto delle pastiglie che si consumano settimanalmente così da evitare tutte le settimane di fare il conteggio e quindi alleggerire il lavoro notturno degli infermieri. È possibile creare un software del genere? Grazie mille per la collaborazione.

    This task requires experience with the Keap/Infusionsoft API. I am wanting to get the "total_paid" value to display on my custom Thank You pages on my Wordpress website. Keap will give us the "order_id" on the Thank You page URL, but you need to contact the API to get the amount paid. I need a basic Wordpress function that can use the order_id in the Thank You page to contact the API and retrieve the rest of the order data and display it on the page (probably in the DataLayer).
