how to send Whatsapp Message using API Hello,Currently i’m using an automation tool called N8N i was using with twilio to send whatsapp messages to our customers, but after checking out manychat and we found it more promising for social channels, we started to migrate into here, so currently when we get a new customer i start create a new subscriber, but i want to be able to send him a message on whatsapp via API, as i want to send him his credentials and some messages on whatsappis there a direct api using message templates? also does it have a variable injection for the template?
