This is a Streamsheets Premium feature.
Sends either arbitrary JSON data or a message to specified producer. Usually this function is used to respond to a previously received request-message. A request-message must provide a requestId property within its Metadata object.
=RESPOND(MessageOrJSON, Producer, requestId)
|MessageOrJSON||Data to send as response.|
|Producer||Name of the Producer to use for sending respond.|
|requestId||The requestId as provided by a previously received request-message|
TRUE on success or error code otherwise.
We assume that a request-message was received and that it provides a
requestId which we store to cell B1 by using the READ function as
READ(INBOXMETADATA(,,"requestId"), B1, "String")
|=RESPOND(OUTBOX("Message"), "Rest", B1)||TRUE||Sends the message with id Message from the outbox to the producer named Rest using the requestId in B1|
|RESPOND(DICTIONARY(A3:C5), "Rest", B1)||TRUE||Sends the JSON data provided by the dictionary function to the producer named Rest using the requestId in B1|
