For easier reading, here is the request json body

{
  "Id": "ABCDABCD1234",
  "Phone": "601234567890",
  "Content": "Message title",
  "Footer": "Text below title, above buttons",
  "Buttons": [
    {
      "DisplayText": "Yes",
      "Type": "quickreply"
    },
    {
      "DisplayText": "No",
      "Type": "quickreply"
    },
    {
      "DisplayText": "Visit Site",
      "Type": "url",
      "Url": "https://www.google.com"
    },
    {
      "DisplayText": "Callme",
      "Type": "call",
      "PhoneNumber": "601234567890"
    }
  ],
  "ContextInfo": {
    "StanzaId": "EDCBABCDEDCBABCDEDCBA",
    "Participant": "60123456789@s.whatsapp.net"
  }
}

No matter what I did, I only get 404 PAGE NOT FOUND message.
Is the chat/sent/template working, or I did a mistake somewhere that I didn't realize ?
Thank you for your time and work.
