Questions
What does it need to run?
An n8n account. You connect your own accounts after importing it; none are included.
What starts it?
It starts on another system calling it.
Does it use AI?
No. Every step is fixed logic or a call to a service, so it does the same thing every time.
How long does it take to set up?
Plan an afternoon. 18 steps is enough that you should read each one before running it.
How do I import it?
Copy the workflow, open a new workflow in n8n and paste. The steps appear on the canvas, ready for your own accounts.
Nothing here has been tested by us. It is somebody's working automation, read and described from its own steps. Treat the connections it wants as a list of accounts it will touch, and read the 18 steps before you point it at anything that matters.
