whatsapp api , dynamic url button ,parameter missing

I'm trying to use a template containing a dynamic URL button, but I keep getting the following error:

{
    "error":{
        "message":"(#131008) Required parameter is missing",
        "type":"OAuthException",
        "code":131008,
        "error_data":{
            "messaging_product":"whatsapp",
            "details":"buttons:utton at index 0 of type Url requires aparameter"
        },
        "fbtrace_id":"A5zKyCl8YbQvpCIT7mgmgtC"
    }
}

What am I missing? I'm using PHP curl to send the message. Sending the hello_world default template with no parameters works fine.

This is the query I use:

{
  "messaging_product": "whatsapp",
  "to": "001555444555",
  "type": "template",
  "template": {
    "name": "invitation",
    "language": {
      "code": "he"
    }
  },
  "components": [
    {
      "type": "body"
    },
    {
      "type": "button",
      "sub_type": "url",
      "index": 0,
      "parameters": [
        {
          "type": "text",
          "text": "1234567"
        }
      ]
    }
  ]
}

Solution

It looks like you have not read the documentation properly, I can see you have not prepared the proper request object,

https://developers.facebook.com/docs/whatsapp/cloud-api/guides/send-message-templates https://developers.facebook.com/docs/whatsapp/cloud-api/reference/messages#template-object

I don't know your template sections, but this is just a predicted request as per your request,

the components property should be inside the template property
If you don't have any parameters in the body text then no need to pass the body in the request

{
  "messaging_product": "whatsapp",
  "to": "001555444555",
  "type": "template",
  "template": {
    "name": "invitation",
    "language": {
      "code": "he"
    },
    "components": [
      {
        "type": "button",
        "sub_type": "url",
        "index": 0,
        "parameters": [
          {
            "type": "text",
            "text": "1234567"
          }
        ]
      }
    ]
  }
}
