I connected Yandex Money API to my web page, but when I’m trying to send the test notice then it doesn’t send to me because (I don’t know because). I wrote to help center to Yandex, they answered to me that “It’s your problem with the server”.
Maybe it’s because of Cloudflare because it’s everywhere encrypt(s?) data.
If It’s not possible to decide this problem then I’ll leave from the Cloudflare (Let me know)
My native language isn’t English. Sorry for my mistakes
So basically Yandex is posting a request to your Cloudflare protected server (I presume the record is , is it not)?
This is most likely a Cloudflare challenge page. You can try to whitelist the IP address or network in question. Do you have access to the exact and full response Yandex receives?
