i want to sent price rate every morning to my customers. So want to know is it possible with whats app business api / any other way. Im a java developer so i can create a project for this.

I'm developing an Android app that creates a whitelist of over 400 contacts and groups of WhatsApp to send them a scheduled message. I found an API to send a message using WhatsApp by passing the message and the receipt contact (person or group), but I didn't find another API to get all group ids of WhatsApp.

How to retrieve all WhatsApp groups' ids, using Android Java?

I am using WhatsApp Business API and in conversation, I want to know the message I have sent has been read or not by the receiver.

I have got response as 'sent', 'delivered' and other but not the 'read'.

I also have checked on my number (WhatsApp Privacy Setting) where I have set "Read receipts" enabled, if this was the case.

Could any one please help me to sort it out?

I have my own Whatsapp business account. I want to have a client that can:

1. Alert me when I get a new message
2. Be able to send an automatic reply based on the original message I've received.

I've searched the web for ready open source python clients I can use and found only one that might be suitable - https://pypi.org/project/wabclient/ The problem - there is no documentation on how to use it, reviews etc. Are there any other open sources I can use to achieve my goal? Any sample projects that use wabclient?

I would like to implement notifications through WhatsApp API into my app. I've done lots of research but I couldn't find anything official.

Officially WhatsApp API Bussiness exists, but it is a beta version and only for companies that send massive volume of messages (1 million+). There is also Twilio, it requires a business approval and I got denied because (again) my volume requirement isn't into the millions of messages per month.

Unofficial libraries exist that potentially could get the job done. I looked into it and the one that I was contemplating seemed to be unreliable. But is this really the only way?

Since the start of pandemic I've been receiving all sorts of ads with apps that offer WhatsApp notification for orders and customer services... how are they doing it? I know they are small businesses, so there must be a way.

My app was built using JavaScript/React, any information is appreciated.
