`"deleteInput"`

JSON hub `"deleteInput"` action deletes an input in FairCom Edge

The "deleteInput" action removes a previously created input definition as long as no output definitions are using it. A failure response lists the output definitions that prevent the input definition from being deleted.

Inputs collect tags from a data source and insert them into an integration table.

Note

A tag is a piece of named data with an associated value. For example, the tag temperature 70 includes both the named data temperature and the value 70. In JSON, a tag is a JSON property, such as "temperature": 70. In a SQL table, a tag is a data field, such as a field named temperature with a value of 70.
