# Overview

> Learn about Cogfy Workflows and how to manage them in Cogfy Messenger

Workflows are the heart of Cogfy's message handling, a low-code chatbot building platform and seamless integration with Meta's WhatsApp.
Connect nodes with different functionalities, make agents decide which path to follow, generate replies, combine different agents, and much more.

## Workflow Types

Workflow types refer to the different triggers to a workflow.
Currently Cogfy supports one type of workflow: Message Received.

* #### Message Received

  Message received workflows are triggered by any message the published workflow number receives.

## Nodes

Nodes are workflows' building blocks.

<Info>
  This is a simple overview, for more information, go to the specific node page.

#### Trigger Nodes

As mentioned, trigger nodes are related to the workflow type. They are the starting point of your workflow.

#### Core Nodes

The most basic functionalities to create a complete chatbot.

They include executing an HTTP Request, running [JavaScript Code](guide/workflows/nodes/core/java-script-code-node), using an Assistant chat completion and sending different types of messages.

#### Logic Nodes

Conditionals and path routing. Currently Cogfy supports one logic node: the If Node.

#### Action Nodes

Perform actions inside Cogfy, like Creating an Internal Message or Updating a Contact.

## Edges

Edges are what bind different nodes together. By clicking and dragging handles, you can connect two nodes, defining a workflow path and enabling interpolation.

## Requirements

You need a **phone number** to publish a workflow and make it available to your users. Please refer to the [phone number documentation](/guide/phone-numbers/connect-phone-number) for more information.
