Template Components

Templates are made up of four primary components which you define when you create a template: header, body, footer, and buttons. The components you choose for each of your templates should be based on your business needs. The only required component is the body component.

Some components support variables, whose values you can supply when using the Cloud API or On-Premises API to send the template in a template message. If your templates use variables, you must include sample variable values upon template creation.

Headers

Headers are optional components that appear at the top of template messages. Headers support text, media (images, videos, documents), and locations.

All templates are limited to one header component

Text Headers

You can choose to add header text to your message template. The message text in the header component accepts parameters for programmatic configuration.

Text parameters can be configured in one of two formats:

  • Positional — Pass in an array of parameters that correspond to numeric positions in the body text with examples
    • For example: “Hello John, your account balance is {{1}}” | [ “$1,000” ]
  • Named — Pass in JSON objects that contain a parameter name and examples
    • For example: { "param_name": "account_balance", "example": "$1,000" }

Component Syntax

Add this header component object into the ”components”[] object array when calling the POST <WHATSAPP_BUSINESS_ACCOUNT_ID>/message_templates endpoint. Substitute the placeholder properties below using the properties table.

{
  "type": "HEADER",
  "format": "TEXT",
  "text": "<HEADER_TEXT>",

  "example": {
    "header_text": [
       // You must provide one of the inputs below when the <HEADER_TEXT> string contains parameters
       <POSITIONAL_PARAM_EXAMPLES>
       <BODY_TEXT_NAMED_PARAMS>
    ]
  }
}

Array of String in which each string is meant to illustrate the text likely to be passed in as a parameter during message send time, for example a bank account balance, or a customer name.

The number of strings must match the number of variables included in the string.

["December 1st"]

<HEADER_TEXT_NAMED_PARAMS>

[JSON Object] | Optional

Array of JSON objects that contain param_name and example strings.

      }
    ]

Media Headers

Media headers can be an image, video, or a document such as a PDF. All media must be uploaded with the Resumable Upload API. The syntax for defining a media header is the same for all media types.

Syntax

{
  "type": "HEADER",
  "format": "<FORMAT>",
  "example": {
    "header_handle": [
      "<HEADER_HANDLE>"
    ]

Body

The body component represents the core text of your message template and is a text-only template component. It is required for all templates.

The message text in the body component accepts parameters for programmatic configuration.

Text parameters can be configured in one of two formats:

  • Positional — Pass in an array of numbered positional parameters that correspond to numeric positions in the body text with examples
    • For example: “Hello {{1}}, your account balance is {{2}}” | [ “John”, “$1,000” ]

Footers are optional text-only components that appear immediately after the body component. Templates are limited to one footer component.

Syntax

{
  "type": "FOOTER",
  "text": "<TEXT>"
}

Properties


Placeholder Description Example Value

<TEXT>

Text to appear in template footer when sent.


60 characters maximum.

Use the buttons below to manage your marketing subscriptions

Example

{
  "type": "FOOTER",
  "text": "Use the buttons below to manage your marketing subscriptions"
}

Buttons

Buttons are optional interactive components that perform specific actions when tapped. Templates can have a mixture of up to 10 button components total, although there are limits to individual buttons of the same type as well as combination limits. These limits are described below.

Buttons are defined within a single buttons component object, packed into a single buttons array. For example, this template uses a phone number button and a URL button:

{
  "type": "BUTTONS",
  "buttons": [
    {
      "type": "PHONE_NUMBER",
      "text": "Call",
      "phone_number": "15550051310"
    },
    {
      "type": "URL",
      "text": "Shop Now",
      "url": "https://www.luckyshrub.com/shop/"
    }
  ]
}

If a template has more than three buttons, two buttons will appear in the delivered message and the remaining buttons will be replaced with a See all options button. Tapping the See all options button reveals the remaining buttons.

Copy Code Buttons

Copy code buttons copy a text string (defined when the template is sent in a template message) to the device's clipboard when tapped by the app user. Templates are limited to one copy code button.

Syntax

{
  "type": "COPY_CODE",
  "example": "<EXAMPLE>"
}

Properties


Placeholder Description Example Value

<EXAMPLE>

String to be copied to device's clipboard when tapped by the app user.


Maximum 15 characters.

250FF

Example

{
  "type": "COPY_CODE",
  "example": "250FF"
}
