Can I check if a user’s phone number is enabled for WhatsApp?

Currently, we do not offer an API to check if a user’s phone number is WhatsApp enabled.

WhatsApp requires businesses to collect an active user opt-in to message them via WhatsApp. This should serve as knowledge that the user has WhatsApp installed on his/her phone.

    🚫 Sending a WhatsApp message to a phone number that is not WhatsApp enabled will fail and fallback to SMS.
