I am trying to set up for Whatsapp business API.
Referring to the Link for setup.

I am working on windows 10 OS. -- Just for Info.

In the section initial setup, on command docker-compose up -d I get the error.

Missing mandatory value for "image" option in service "wacore": Run docker-compose with env var WA_API_VERSION (ex. WA_API_VERSION=2.21.4 docker-compose )

Thank You.

When you begin your business using Twillio for sms verification is pretty expensive, I was looking for a free/very cheap service for the beginning.

I can see that Facebook provides - Whatsapp business API and it's unclear if you can already use it to send messages as an individual developer. https://developers.facebook.com/docs/whatsapp/

I can see that Twillio also have a Whatsapp API which costs money.

Is there a way to send Whatsapp messages today ?

Is there other affordable choice to verify new users by sms ?

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 :-)
