I used NIPAP about seven or eight years ago. It's quite customizable and easy enough to code against but not the easiest to work with, overall. It has some quirks. I think I would have chosen Netbox had it been as mature as it is now.

Netbox for the win! You can not only use it for IPAM but for circuit inventory, designs, cross connects, rack layouts and automate from there. It serves as a true source of truth. I think you will be pleased.
