About the Function Types API

The Function Types API allows you to retrieve the available function types on a site. Function types are predefined categories of functions that Wix business solutions provide, defining when and how custom logic can be integrated into Wix workflows. Use this API together with other Wix Functions APIs.

With the Function Types API, you can:

• Find all the points where you can inject custom logic into Wix business solution workflows.
• Understand what function types each installed business solution provides.
• Identify which function types are available before building custom functions.

Function types in the Wix Functions ecosystem

Function types are the starting point for all functions. They define the integration point where your function's custom logic runs.

Wix business solutions define function types and make them available only on sites with the business solution installed.
