handlers schema section
Query handlers are items of the HandlerChain mechanism which enables you to describe business logic as an action request and a chain of handlers. Examples of handler invocation are available in separate articles: Page customization.
Generic query handlers include actions to open pages, work with data on pages, etc.
Generic query handlers available in Creatio 8 Atlas are available below.
