How to Send WhatsApp Messages

​
During a Call (Action-Based)

You can configure your assistant to send WhatsApp messages during or after a call using the sendMessage action with Zeplo configuration. Follow these steps:
  1. Go to Assistant Settings under Call Platforms
  2. In the Actions section, add a new action of type sendMessage
  3. Configure the Zeplo settings:
    • is_zeplo: Enable Zeplo WhatsApp messaging
    • description: Condition text describing when to send the message
    • content: Zeplo template configuration:
      • templateName: Name of the approved WhatsApp template
      • language: Template language code (e.g., en_US)
      • category: Template category (MARKETING, UTILITY, or AUTHENTICATION)
      • parameter_hints: Array of hint strings for AI to extract values for placeholders
      • parameter_slots: Array of slot objects describing placeholder positions
    • end_call_sms: Send message after the call ends
    • end_call_sms_not_answered: Send if call is not answered

WhatsApp Template Guidelines

  • Templates must be pre-approved by WhatsApp before use
  • Each template has a specific category (Marketing, Utility, Authentication)
  • Templates support dynamic parameters using numbered placeholders (e.g., {{1}}, {{2}})
  • Messages outside the 24-hour session window must use approved templates

​
Best Practices

  • Get your templates approved well in advance
  • Use clear and relevant template names
  • Test templates with sample data before launching campaigns
  • Keep parameter hints descriptive for accurate AI extraction
