[[input-simple]]
==== Simple Input

An <<input, input>> that enables you to load static data into a watch's execution context as the initial payload.  
The `simple` input is useful when the data you want to work with doesn't need to be loaded dynamically, but for
maintainability you want to store the data centrally and reference it with templates. 

You can define the static data as a string (`str`), numeric value (`num`), or an object (`obj`):

[source,json]
--------------------------------------------------
{
  "input" : {
    "simple" : {
      "str" : "val1",
      "num" : 23,
      "obj" : {
        "str" : "val2"
      }
    }
  }
  ...
}
--------------------------------------------------

For example, the following watch uses the `simple` input to set the recipient name
for a reminder email that's sent every day at noon.

[source,json]
--------------------------------------------------
{
  "trigger" : {
    "schedule" : {
      "daily" : { "at" : "noon" }
    }
  },
  "input" : {
    "simple" : {
      "name" : "John"
    }
  },
  "actions" : {
    "reminder_email" : {
      "email" : {
        "to" : "to@host.domain",
        "subject" : "Reminder",
        "body" : "Dear {{ctx.payload.name}}, by the time you read these lines, I'll be gone"
      }
    }
  }
}
