Web Data Connectors (WDCs) in Tableau are a powerful feature that allows users to connect to and extract data from web-based sources, APIs (Application Programming Interfaces), or custom data sources that are not natively supported by Tableau. They enable Tableau users to access data from a wide range of web services, such as social media platforms, online databases, cloud-based applications, and other web-based resources, and incorporate that data into their Tableau visualizations and analyses.

WDCs act as a bridge between Tableau and web-based data sources. They provide a way to define a connection to a web service, specify the data retrieval and transformation logic, and bring the data into Tableau in a structured format. This capability is particularly valuable when working with dynamic or frequently updated data from web sources because WDCs allow users to refresh the data in Tableau on-demand, ensuring that visualizations stay up to date.

To create a Web Data Connector in Tableau, developers typically write HTML, JavaScript, and TypeScript code that defines the connection details, authentication methods, data extraction process, and data structure. Tableau's WDC framework provides a set of JavaScript APIs and libraries to simplify this development process. Once the WDC is built and hosted, users can access it from within Tableau Desktop or Tableau Server, enter any required credentials or parameters, and use the data just like any other data source within Tableau.
