Container Input (JSON)

This nodes allows injecting a JSON value from outside, e.g. via the advanced batch executor or server-exposed workflow, into the workflow. The JSON value is returned as a single JSON cell in the column json.

Options

Parameter name

A unique name for the input parameter. This name is exposed in the REST interface and in the Call Workflow node.

Append unique ID to parameter name

If checked, the name set above will be amended by the node's ID to guarantee unique parameter names. Usually it's a good idea to have this box not checked and instead make sure to use meaningful and unique names in all container nodes present in a workflow.

Description

A description for the input parameter. The description is shown in the API specification of the REST interface.

JSON

The text representing a default JSON value. It might contain comments between

/* */

or after # or // until the end of line.

Output Ports

Table containing a single JSON value in the column json.
