Just for some closure and in case it helps others. Yes, it was Cloudflare causing the problem. I whitelisted NOWPayments IP addresses (as given to me by Google's Gemini) and skipped all security checks for the hook's url.

I'll see if I find a way for that url to bypass Cloudflare. It was pretty easy before with a page rule, but they deprecated that. When I used to have Coinbase Commerce, the webhook had a rule that excluded it.

Hi @Kirill Gromov , I've only had two payments so far, so I'll probably need a few more to see if the following always happens: NOWPayments marks the payment as finished, the money comes through, but the IPS transaction is not automatically approved. I had to approve the invoice in both occasions. The first time I wondered if maybe I should have waited a bit more, but the second time was hours later when I saw the transaction was still waiting approval. I don't think the system's errors logs have anything related to this and the debug mode of the payment gateway is on. I use Cloudflare, so I wonder if that may have something to do with it.

Great, I'll give it a go. Cheers!

Hi @Kirill Gromov how is it going? Does this file works on IPS 4.7? I'm thinking of starting an account on NOWPayments but I'm still running IPS 4.7.
