website for sending bulk messages (whatsapp)

Please read the full description of the project before bidding or applying for the position.

I need to send in average per day 250 to 300k whatsapp messages.

I need the developer to develop my own Api and make an online dashboard system that allows you to send mass messages to WhatsApp.

The desire system I wanted is 95% similar to this given site. Please have a demo account for testing, no need to sign up.

I have already tested many systems to send whatsapp in bulk.

Some web and other systems that run on windows (desktop).

Ok, that's it, below the system description:

If you have a web system ready you will be very welcome, if you have already made a similar website will also be welcome.

Develop a whatsapp integration API so that the system can send messages independently.

Have a proxi, smart features to keep your account safe and unlocked with anti-lock algorithm by whatsapp.

Details:

1. I need to automatically send whatsapp videos, images, text and audio. Bidder needs to tell me how many whatsapp every day or every hour

2. Let me upload the contact list via csv or excel

3. You can detect and detect the phone number from the contacts list for sms or whatsapp (if you have whatsapp use whatsapp)

the system should detect whatsapp whatsapp, if so, 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 may also receive text and image messages from whatsapp.

6) Proxies

7) One more detail, I would like the system to have an option to create dynamic variables, when creating a project and sending the messages see example:

Important !!!

This is a template, both variable names and their contents can be changed according to the needs of the client or each project.

Hello, <VAR A = "name of the person"> we are company <VAR B = "Company Name">, we inform you that the parcel number <VAR C = "Parcel Number">, with the value of <VAR D = Value parcel "> is delayed. If you are interested in more details, please call <VAR F =" Company Phone ">, or access our website <VAR F =" Company Website ">, thank you.

The excel with the base of telephones that I will import will be exactly according to the fields inserted in the system.

8) Please correct me if you are wrong or give me your suggestions ok ...

Note: Adding the sender IDs - I've heard that the app doesn't allow you to send more than 100 or 50 messages at a time, which means you may need to change the sender IDs after every 50 submissions and add sender IDs checked the application number., as explained below.

I would also like to be able to add several channels (whatsapp numbers) to the system, and at the time of registration you have the option to link these channels to an existing project or not.

You have the option of also generating caster of these channels (numbers whatsapp), typing in a field how much time will be made: 10 submissions - 20 submissions - 50 submissions and change to the next channel.

if I bind to an existing project example:

I created 10 channels (whatsapp numbers) and linked those 10 channels to project "A", only this "A" project can use those channels.

if it is set up the channel caster (whatsapp numbers) to send 30 messages and change channels then the system will use the 10 channels (whatsapp numbers) and make the change every 30 sends.

This way I imagine it will be more difficult for whatsapp to block the channels (numbers whatsapp) correct?

Payment will only be made after completion and testing on the system.

I'm sorry I've already lost a lot of money with developers who start working and do not end up with whatsapp updates their algorithm and the system stops working.

So they abandon the project and I'm left without the system and out of money.
