Generally available
When a watch is triggered, its input loads data into the execution context. This payload is accessible during the subsequent watch execution phases. For example, you can base a watch’s condition on the data loaded by its input.
Watcher supports four input types:
simple: load static data into the execution context.search: load the results of a search into the execution context.http: load the results of an HTTP request into the execution context.chain: use a series of inputs to load data into the execution context.
If you don’t define an input for a watch, an empty payload is loaded into the execution context.
