description: Documentation for the Tableau Web Data Connector
---
**Deprecated** - This repository will be removed with the Tableau 26.3 release.

The Web Data Connector 3.0 framework is deprecated and will not receive further updates. Migrate to the [REST API Connector on Tableau Exchange](https://exchange.tableau.com/products/1111)—built by Tableau, supports JSON and CSV over HTTP GET, Basic/Bearer/OAuth authentication, and runs on Tableau 2023.3 and later. Note: this connector is extract-only and requires a JDBC driver installation.

# Web Data Connector Overview

  

Tableau’s Web Data Connector (WDC) lets you connect to data that is accessible over HTTP. A WDC is an HTML file that includes JavaScript code.

**Note:** Unlike previous versions, Web Data Connector 3.0 doesn't require that your HTML file is on a web server.

## Components of Web Data Connector 3.0

WDC 3.0 has the following components.

### Extensible Protocol Server

The Extensible Protocol Server (EPS) is the server that runs your web data connector. An EPS-based connector is a web application that doesn’t require a web server.

### TACO Toolkit

The TACO Toolkit is the command-line interfact that you use to create, build, and package your web data connector. Use the TACO Toolkit to generate template files for a variety of connector types and then edit the files for your specific connector. For more information about creating connectors, see [Build a sample web data connector](https://help.tableau.com/v0.0/api/webdataconnector/en-us/index.html).
