Have a look at this thread about merging messages... > [@Merging Values to a single payload](https://discourse.nodered.org/t/merging-values-to-a-single-payload/92947/2): > > It is unclear to me what your problem is since you don't explain what the sources of the data are (what nodes they are), how you inject 'inject' the data. Please create a small flow demonstrating your problem and post it to a reply. In order to make code readable and usable it is necessary to surround your code with three backticks (also known as a left quote or backquote ```) ``` code goes here ``` You can edit and correct your post by clicking the pencil pencil2 icon. See this post… Might be worth taking a look at this CookBook article as well... [https://cookbook.nodered.org/basic/join-streams](https://cookbook.nodered.org/basic/join-streams) **EDIT:** The above method relies on the input messages to be merged having DIFFERENT topic-names. It is unclear what the topic-name is for your two sets of incoming data and whether a unique topic-name could be applied (at the source where the data is created). --- _[View the full topic](https://discourse.nodered.org/t/merge-two-payload-messages-based-on-same-value-in-both-payloads/93562)._
