Setting up an **AI agent to respond on WhatsApp** requires three pieces: a number connected via the **WhatsApp Business API (Meta)**, approved **message templates** to reopen conversations, and the **AI Agent** configured with the process's instructions. In **Jestor**, these three pieces already connect natively.

## What's the difference between responding on regular WhatsApp and with an AI agent?

On regular **WhatsApp**, every response depends on someone typing it manually. With a configured AI agent, the initial response already goes out automatically, with the team monitoring and stepping in when a case falls outside the pattern.

## What companies are trying to solve?

- High first-response time outside business hours
- Repeated messages that always need the same standard reply
- No standardization across different agents
- Difficulty reopening the conversation once the 24-hour window closes

## How to configure the AI agent step by step?

Setup goes through three stages: connecting the number, defining templates, and configuring the agent.
