I'm using node-red on one of my projects. And I'm having trouble handling two message payloads in one node. I DO NOT want to deal with them SEPARATELY, instead I want this node to combine both inputs into ONE. All the answers I found online were talked about how to deal with them in sequence, I DO NOT want that. I need to make them into ONE message payload and pass to the next node. Anyone has any insight on this?

You can use DataWeave to merge three different payloads into a single one using the service line value. Join the DZone community and get the full member experience. There are a lot of questions on StackOverflow about merging multiple payloads into a single one using a primary key.
Payload 1: Original Payload Variable (note: before transformation, set this as the payload). Payload 2: Store in flow as Variable 1. Payload 3: Store in flow as Variable 2. Now, use DataWeave to merge all three payloads into a single one using the service line value.
Use the Join node. This can be set to combine 2 incoming messages so that the new msg.payload is an array containing the msg.payload of the input messages. Show activity on this post. Do also check out node-red-contrib-fusion which may or may not be overkill depending on your specific use case.
When speaking about multiple payloads, these scenarios come to my mind: When you open a function node, below the editor there is an option to add multiple outputs to your node.
Use the Join node.
