improvement - phone number check

[behind24proxies]

with the venom engine when you verify the existence of phone numbers it never returns a false , it simply times out.
in other words if the phone number is not on whatsapp it does not return a response.

Hi! We've added contacts endpoints in WAHA

Right now it supports:

• Get all contacts or a single one
• Get "about" contact (aka status)
• Get contact's profile picture
• Check phone number is registered in WhatsApp (works even if the number is not in your contact list)
• Block and unblock contacts

It supports default engine, so no needs to use venom for phone number check. Please have a look, it may help you!

The endpoints are available in WAHA Plus 2023.1 version and we'll add them in Core version in February 2023
