How to Set Up WhatsApp chatbot for business with Trengo

First, you need a WhatsApp Business API account. After that, you need Trengo as an automation tool to take over things. With this platform, you can set up a chatbot or a flowbot; let’s discuss how these two differ.

Flowbot by Trengo

The chatbot can understand your customer’s query by recognizing specific keywords and formulating an answer. You fill in answers to train the bot, the more variations, the smarter the bot. With a flowbot, your shoppers can find the answers they seek by getting multiple-choice options and choosing the appropriate option.
