We will need an app that using WhatsApp Business API will
a - Get a list of Whatsapp groups to scan
b - Get a list of keywords to search
c - locate all messages that contains the keywords
d - make a photo (screenshot or other) of the located messages
e - save the photo data (origin group, user, times etc ..) in a text file and save the photo on a disk
App should be installed on google app engine. (we will supply credentials)
Please bid if you have experience with WhatsApp API and you have samples you can show.
Future projects will implement the same mechanism for Telegram & Facebook so If you have experience with such, and you can show it, It will be an advantage.
Payment will be done by Milestones
