Unable to send Templates with Buttons

[ashuio]

When making a template request api cll to facebook the following json is used

{
  "messaging_product": "whatsapp",
  "to": "911234567890",
  "type": "template",
  "template": {
    "name": "template_name",
    "language": {
      "code": "en"
    },
    "components": [
      {
        "type": "header",
        "parameters": [
          {
            "type": "image",
            "image": {
              "link": "http://example.com/files/cover.jpg"
            }
          }
        ]
      },
      {
        "type": "button",
        "sub_type": "phone_number",
        "index": "0",
        "parameters": [
          {
            "type": "text",
            "text": "+919876543210"
          }
        ]
      },
      {
        "type": "button",
        "sub_type": "url",
        "index": "1",
        "parameters": [
          {
            "type": "text",
            "text": "http://example.com/about"
          }
        ]
      }
    ]
  }
}

But Meta gives the following error

"(#100) Param template['components'][1]['sub_type'] must be one of {BOOKING_CONFIRMATION, CATALOG, COPY_CODE, FLOW, MPM, ORDER_DETAILS, QUICK_REPLY, REMINDER, URL, VOICE_CALL} - got \"phone_number\"."

The following JSON Works though
(Tested With Graph explorer v24.0)

{
  "messaging_product": "whatsapp",
  "to": "919876543210",
  "type": "template",
  "template": {
    "name": "template_name,
    "language": {
      "code": "en"
    },
    "components": [
      {
        "type": "header",
        "parameters": [
          {
            "type": "image",
            "image": {
              "link": "http://example.comfiles/cover.jpg"
            }
          }
        ]
      }
    ]
  }
}

@pu-raihan Thanks for the PR to add support for this.

Hi, the problem is in the second component, this one
{
"type": "button",
"sub_type": "phone_number",
"index": "0",
"parameters": [
{
"type": "text",
"text": "+919876543210"
}
]
},
Available options are "BOOKING_CONFIRMATION, CATALOG, COPY_CODE, FLOW, MPM, ORDER_DETAILS, QUICK_REPLY, REMINDER, URL, VOICE_CALL"; if you wanna start a whatsapp session! it's not possible for security reason, you can start a new call using voice_call
