"listInputs"

JSON hub "listInputs" action obtains a list of names of previously created FairCom Edge inputs

The "listInputs" action obtains a list of names of previously created inputs. 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.

Essential information

  • You can return a filtered list by specifying a partial name in the "partialName" property.

  • You can include additional items in the list by searching for words contained in the item's metadata.

  • To get detailed information about specific inputs, use "describeInputs".
