I have a question on the stackby node -
How do you update a record? The only workaround I can think of is to list all the records, find what I need, delete it and then append it as a new record (with the updated data). It may be easier to use the HTTP module.
I am tagging @Smit_Parmar because I found an old post from him when he added this node
(Select the nodes and use the keyboard shortcuts CMD+C/CTRL+C and CMD+V/CTRL+V to copy and paste the workflow respectively)
