Good rec, @PhilipDAth !
@golden-goat sorry to hear about the struggle! It sounds like you already have a config template, and now you're trying to create more networks and bind them to that template? If so, Philip's rec is a good one here -- you may not need to use APIs for this.
If that tool doesn't meet your need, please share some more detail about what you'd like to be able to get done and we can point you in the right direction.
