A Whatsapp PHP Web App used to send mass messager to a list of contacts
Based on the Chat-API 2.5 (https://github.com/mgp25/Chat-API), this Web APP is very useful for sending mass messages to a large list of contacts.
Note: Only a few messages were being sucessfully and then the number would get blocked by Whatsapp, and since Chat API is no longer supported, this APP has been discontinued.
