Request Body

Parameter Required Description
lead_contact ✅ Lead contact number
lead_name ❌ Lead name (optional)
template_name ✅ WhatsApp template name
template_params ❌ Values for template variables. Use a list to match by order, or an object to match by name.
websitebuttonparams ❌ List of dynamic URL suffix values for URL buttons that have {{1}} in their URL. Values are matched in order of button appearance.
copycodebutton_params ❌ Coupon code string for the Copy Code button.

Example Request Body (Ordered Variables)

{
  "lead_contact": "9816923811",
  "lead_name": "Shiva",
  "template_name": "order_update",
  "template_params": ["OD1234", "Delhi"]
}

Example Request Body (Named Variables)

{
  "lead_contact": "9816923811",
  "lead_name": "Shiva",
  "template_name": "order_update",
  "template_params": {
    "order_id": "OD1234",
    "city": "Delhi"
  }
}

Example Request Body (With Button Parameters)

If your template has dynamic URL buttons and/or a Copy Code button:

{
  "lead_contact": "9816923811",
  "lead_name": "Shiva",
  "template_name": "promo_template",
  "template_params": {
    "name": "Shiva",
    "order_id": "OD1234"
  },
  "website_button_params": ["shiva123", "order/OD1234"],
  "copy_code_button_params": "SAVE20"
}

Note: website_button_params values are appended to the dynamic URL in order. For example, if your template has a button URL https://example.com/track/{{1}} and you pass ["OD1234"], the final URL becomes https://example.com/track/OD1234. Static URL buttons (without {{1}}) do not need any parameters.

Example Request Body (With Header Media)

If your template has a media header (Image or Document):

{
  "lead_contact": "9816923811",
  "template_name": "event_invite",
  "template_params": ["Annual Gala", "March 25th"],
  "header_media_url": "https://example.com/invitation_card.jpg",
  "header_media_name": "invitation.jpg"
}

Note: header_media_name is especially useful for Document templates where you want to specify the filename that the user sees when they download the document. If not provided, TailorTalk will try to extract the name from the URL.

  • Messages sent via this API will be visible in the lead's chat history.
