Hi @PBJ , that is correct, the Wait node is to be used with a loop in this case.
I’m not sure which Request node you are using, but both the GET and POST Request nodes have the “wait” configuration that you are mentioning, in the form of Delay and Concurrency:
In your case, you want to set the Delay to 1000 ms, which is 1 second, and Concurrency to 1, which means it will send 1 request at every 1 second.
