If you have a web ready system will be very welcome, if you already made a similar website will also be welcome.
1. I need a site to automatically send whatsapp videos, images, text and audio. Bidder needs to tell me how many whatsapp can be sent every day or every hour
2. Let me upload the contact list via csv or excel
3. You can detach and detect the phone number from the contacts list for sms or whatsapp (if you have whatsapp use whatsapp)
the system should detect if a phone number has whatsapp, if so, send whatsapp.
4. report interface shows how many phone numbers have whatsapp, how many whatsapp are successfully sent, how many are not successfully sent, many received whatsapp and whatsapp read expired.
5. The site can send text and picture messages to whatsapp. In addition, the site can also receive text and image messages from whatsapp.
Note: Adding the sender IDs - I've heard that the Whats app does not allow you to send more than 100 or 50 messages at a time, which means that you may need to change the sender IDs after every 50 submissions and add sender IDs checked the application number. So let's say if I send 5000 whatsapp we may need 100 sender ID, so 100 phonenumbrs verified by that is app
7) Easy Sender
