GoDaddy really lived up to its bad reputation and recently changed their API rules. The rules are simple: either you own 10 (or 50) domains, you pay $20/month, or you don’t get the API. I personally didn’t get any communication, and this broke my DDNS setup. I am clearly not the only one judging from what I found online. A company this big gating an API behind such a steep price… So I will repeat what many people said before me (being right): don’t. use. GoDaddy.
I also use porkbun, their API is not a masterpiece but it works and allows you to get, set and update records. In fact their API is now supported by some of the common ddns scripts out there.
