Hello, in this tutorial, I will show you how to update data in Realtime Database using the FBP Plugin for Unreal Engine.
To update data, use the Update Data node from the plugin.

Using the Update Data node to update data.
Then set the path to the data you want to update using the Data Path pin.
For the Data pin, create a document using the Begin Write Document node. Then add content you want to update the data with by using a combination of Add nodes provided in the plugin.
Available Add Nodes
(1) Add String
(2) Add Number
(3) Add Boolean
(4) Add String Array
(5) Add Number Array
(6) Add Boolean Array
(7) Add Map
Adding the Callbacks
Lastly add the callbacks nodes.
Click and hold on the callback pin from the node. Then drag and let go on an empty spot on the blueprint.
Select “Add Event” then “Add Custom Event.” That will create the event node fit for the callback.
The On Data Updated callback gets called when the data is updated successfully.
The On Fail to Add Data callback gets called when it fails to update the data.
