WhatsApp message sending remotely with command -- 3

Job ID: 37279838

Budget: $100 – $300 USD

Need to create an application or interface where my employees (Multiple employees) should be able to send WhatsApp messages to desired different numbers from one same WhatsApp account which will be configured in my one phone only. Employee's phones and my phone in which the WhatsApp is installed, both can be in different locations.

So basically the requirement is that when any employee sends a command to my phone from his Android app, my phone should automatically follow his command and send the WhatsApp message to his desired number which he requested via the app. Also it should support pdf or normal size attachments.

For example:
I have a WhatsApp account with number 9999999999 configured in my phone only, my employees should send an instruction/signal via the developed application to my device and my device should without any manual intervention of mine follow the instructions received by multiple employees and send WhatsApp messages accordingly to the desired numbers requested by them.

The app which will be developed can be always connected with the internet and can be allowed to work 24/7 in the background across all the devices which will be sending and receiving the signals/instructions.

It's only required for Android platform.
