Frequently Asked Questions

What is WhatsApp Business API?

WhatsApp Business API is a powerful communication tool that enables businesses to exchange an unlimited number of messages with customers on WhatsApp.

While WhatsApp API supports chatbot integration, it is not a chatbot in itself but a platform that facilitates interactive customer communication.

WhatsApp Business is a standalone app for small businesses, whereas WhatsApp Business API is designed for medium to large enterprises, offering more extensive features and integration options.

The different conversation categories are as follows:

Utility conversations: Facilitate a specific, agreed-upon request or transaction or update to a customer about an ongoing transaction, including post-purchase notifications and recurring billing statements.

Authentication conversations: Enable businesses to authenticate users with one-time passcodes, potentially at multiple steps in the login process (e.g., account verification, account recovery, integrity challenges)

Marketing conversations: Include promotions or offers, informational updates, or invitations for customers to respond/take action. Any conversation that does not qualify as utility or authentication is a marketing conversation.

Service conversations: All user-initiated conversations will be categorised as service conversations, which help customers resolve enquiries.
