The HSM Template (Highly Structured Message) node sends pre-approved WhatsApp templates to one or more recipients. Templates are fixed-format messages that Meta has previously verified, which allow dynamic fields for personalization.

​
When to use it

HSM templates are mandatory for initiating conversations with WhatsApp users outside the 24-hour window. They are common for:
  • Notifications and alerts
  • Order or appointment confirmations
  • Payment reminders
  • Approved marketing campaigns

​
Configuration

​
General

1

Select a template

Choose a template from the list of available templates in your WhatsApp Business account. You can refresh the list with the refresh button.
2

Define the recipients

Add one or more phone numbers to which the template will be sent. You can use variables such as {{$user.phone}}.

​
Media (optional)

If the template includes multimedia content (image, video, document), upload the corresponding file.

​
Parameters

The dynamic fields of the template appear automatically when you select it. Fill in each parameter with the value or variable you want to insert.

​
Response

If the template includes quick reply buttons, configure the behavior of each one:
  • Link to skill: Redirects the user to another flow when the button is tapped
  • Send text: Responds with a text message
Additional options:
  • Single-use button: Deactivates the buttons after the first selection
  • Parameters in memory: Saves additional values when the user taps a button
