My developers and I have been banging our heads for a while now. We use CCBill as a payment processor for our website, we’ve set it up just fine, customers can order, orders are saved in our database and so on.
However, we are unable to set up the Webhook to work for the sake of it. CCBill sends us a webhook notification but we do not receive it, after we disable cloudflare, it works. So that’s how we realized Cloudflare is the issue.
I’ve done this page rule as well: http://prntscr.com/oyajlx
I’ve whitelisted their IPs in host and cloudflare.
Nothing helps, CCBill tells me there’s a 503 response from us.
Anyone has any suggestions we’d be eternally grateful!
I don’t use CCBill, but there are several posts regarding the service:
Thanks for replying. I sadly didn’t find a solution but you asked in one of the threads to see the code, so here I got this code for you maybe it helps you:
503 then this string
