Problem

Incoming contact webhook payloads currently include the contact displayName and vcard, but the phone number is only embedded inside the vcard. Consumers need to parse the string manually to recover the number.

Current payload

{
  "contact": {
    "displayName": "Alice",
    "vcard": "BEGIN:VCARD...TEL;type=Mobile:+62 812 3456 7890..."
  }
}

Requested change

Expose the contact phone number explicitly in the webhook payload, for example as:

• contact.phone_number for single contacts
• each item in contacts_array should also include a phone number field

Why this helps

• Avoids consumers needing to parse vcard manually
• Makes webhook integrations simpler and less error-prone
• Keeps the payload easier to use for automation and CRM syncs

Acceptance criteria

• Single contact webhooks include a structured phone number field
• Multi-contact webhooks include a structured phone number field for each contact
• Existing vcard behavior remains unchanged for backward compatibility
• Documentation examples are updated accordingly
