Inputsedit

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.
