Send links and simple texts to a WhatsApp
  • Chat
  • Group
  • Recipient
We highly recommend using the send-text-safe endpoint for regular messaging operations to maintain a more natural communication pattern, and keep your whatsapp number safe from being blocked.
If the text has a link - it generates a preview for that link. You can adjust the behaviour by setting
  • link_preview: true - to enable link preview
  • link_preview_high_quality: true - to enable high-quality link preview
