I need a system with the source code, which allows me to upload a list of numbers and that the system validates whatsapp numbers, but also that the name registered in whatsapp for that number, must be developed in visual basic 6, visual basic .net or php, in the proposal must put the real cost of the system.
Greeting,
I have understood your Whatsapp Filter System task and can do it with your 100% satisfaction. Please ping me for more discussion.
I have more than 5 years of experience in .NET, PHP, Software Architecture, VB.NET, Visual Basic
First of all, WhatsApp doesn't provide any API that can be used to implement your requirement. So I propose a solution based on web.whatsapp. I have implemented a similar solution that sends bulk messages to WhatsApp contacts and that can be modified to achieve your goal. I have done it in C#. If VB is mandatory I can do in VB. The cost estimate is:
1. Bot script for whatsapp web, to search the contact - 200
2. Read and parse the file that contains phone numbers - 50
3. Generate output file with contact phone numbers and names - 50
4. Source code - 100
I can supply you a system developed with VB.Net 2010 or VB.Net 2015 that does what you want. Please contact me if you are interested in having me work on your project.
