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.

This is my first post, and I'm a beginner at this so please be kind.

I'm running an integration on an AWS server, and the Slack API Enable Subscriptions page will not verify the Events Request URL. On the Slack API page, I receive the error "Your URL didn't respond with the value of the challenge parameter." but no other information.

Following the instructions here: https://www.tyntec.com/docs/whatsapp-business-api-integration-slack

Everything looks OK until the Enable Events step. where Slack throws the following error:

Here is the git repository https://github.com/tyntec/api-samples/tree/master/wa-integrations/slack

This is my postman code:

{   "webhooks": [{     "events": [       "MoMessage"     ],     "callbackUrl": "https://x.x.x.x/tyntec/forwardWAMessage"   }] } 

can you please nudge me in the right direction?

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?
