I am trying to understand something about WhatsApp group messaging API for businesses. The question is: In order to send a message to a group as a business, does my business user have to explicitly be a member of that group? In other words, I want to create a group with a few of my customers via the API, but to post messages there without the need to have my business user to be explicitly listed among the group members.

I went over their official docs: https://developers.facebook.com/docs/whatsapp/api/messages/group/ https://developers.facebook.com/docs/whatsapp/api/groups/

I also read this post (on which I would comment - if I had enough reputation) : How to send message on WhatsApp Group using official API

I didn't find an answer on this question there. Does anyone know?

Thanks :-)

I have searched for the Whatsapp Business API but not found the official Whatsapp business API samples. What are the limitations of media messages and billing. If any one have information please provide.

I'm trying to follow this guide to start business initiated conversation in WhatsApp. I successfully created the user in the first step, but I cannot link it to the WhatsApp channel.

I'm calling API POST request:

https://api.smooch.io/v1.1/apps/{myAppID}/appusers/{myUserID}/channels 

With body:

{     "type":"whatsapp",     "confirmation":{"type":"immediate"},     "phoneNumber":"phoneNumberInInternationalFormat" } 

But result is:

{     "error": {         "code": "bad_request",         "description": "Linking not supported for whatsapp sandbox integrations."     } } 

So my question - is there any way to send a message using Sandbox number, or I need to register a number by requesting access process?

I am working on Whatsapp Business API. When i am trying to access the API, it shows me an error with

"details": "Connection refused. Please check if wacore is running."

Any help to solve it. This is my Docker Whatsapp container running

This is Postman api post

I have a facebook page which posts image content regularly on it's feed. I want to create a Whatsapp account (preferably a bot) which people can subscribe to with a message, and start receiving all the new posts on the page as Whatsapp message from that number.

The following is the approach I want to follow.

1. Create a subscription mechanism: Save the contact number of all users who send 'SUBSCRIBE' to my number to a broadcast list.
2. Use facebook graph API to check for new posts on my facebook page feed.
3. If there is a new post on the page feed, send the content to broadcast lists created in second step.

The second step can be easily done in python using the well documented graph api. The first and third step however seems complicated as the Whatsapp business API access is subject to approvals and the third party solutions are not well documented. What would be the best approach to implement the first and third steps mentioned above, preferably in python?
