This node passes JSON objects to a workflow, executes the workflow, and fetches the returned JSON objects. This happens once for each row in the input table, appending the fetched results for a row as new cells to the row.
Sending data.
The called workflow can receive data from this node via the Container Input nodes, e.g., JSON, Row, or Table, which all expect a JSON object but make different assumptions on the structure of the object. For instance, Container Input (JSON) accepts any JSON object, while Container Input (Row) expects a JSON object where each key corresponds to a column name and the associated value denotes the according cell content.
What is passed to a specific Container Input node can be configured in this node's dialog. There are three options: pass the JSON contained in a selected column of the current input row, pass a static JSON (that can be overwritten by a flow variable), or send nothing, causing the default JSON object defined by the according Container Input node to be used.
Receiving data.
The called workflow can send back data via Container Output nodes (Row, Table, or JSON). Each Container Output node will result in a column being appended to the output table.
