​
Important Notes​

​
Technical Details​

  • Audio is generated with the ElevenLabs API and sent as a WhatsApp voice note
  • Requires a valid ElevenLabs API Key with Text-to-Speech and Voices permissions
  • Leaving WhatsApp Number empty uses your dashboard’s number-selection priority
  • Works with all standard CRM workflow triggers

​
Best Practices​

  • Keep messages concise - we recommend under 2-3 minutes (approximately 300-450 words)
  • Use relevant variables only
  • Test before publishing
  • Avoid over-messaging - too many messages cause fatigue
