Development of a web based program to send messages with Whatsapp like an email autoresponder

I will need a web based program that send messages to a list of whatsapp numbers with:

- can store an amount of ilimited separated lists of numbers.

- need to allow unlimited number of users where each one will manage their own account.

- all data will be stored on the platform database

- a list can have a sequential list of messages (as in an autoresponder email), and the messages are trigged manually.

- Each list can be associated with a diferent whatsapp number sender.

- Have an admin account to give users access for a specified time (3 months, 6 months, 1 year)

- Possibility to send broadcasts, according to the date and time, the messages may be "scheduled";

- To be able to configure the interval of each sending by list (for example, between 3 and 10 seconds)

- Be able to use variables in messages, such as the name of the person who receives the message.

- To be able to upload files with phone number, name and other fields.

So you can have an ideia of a program you can check this website: [login to view URL]

But this one is a local program instaled in a computer, I want web based on my server.

That program is also limited because doest store numbers and dont have diferent lists, only send to the numbers uploaded.

And (For now) I dont need autoreply, perhaps in the future.

when apply write "GREAT" on the beggining of you proposal, so i know you have read everything until here.

It will be a continuous project since it will be necessary to maintain the program due to the constant changes that whatsapp has in its API and necessary changes to the program over time
