WhatsApp Link Generator

Use this endpoint when you need to programmatically generate WhatsApp click-to-chat links from phone numbers, especially when building landing pages, CRM integrations, or digital business cards that require deep-linking directly into a WhatsApp conversation with an optional pre-filled message. Prefer this over manual link construction to ensure correct URL encoding of the message and proper formatting of the phone number.

• Missing or invalid phone number format returns an error or empty result
• Phone number not in international format may produce a malformed link
• Empty result object if the phone number fails validation
• Network timeout or server error returning a non-200 response
