In WhatsApp API, there is no app and front-end interface. Instead, end-users (businesses) are required to take the WhatsApp API endpoint and integrate it into their business software. Once you have signed up with one of WhatsApp’s BSPs or accepted into the limited public preview, you can create a WhatsApp business account and decide your line of credit.
Once you are done with account setting, create your own templates for sending messages to customers.
