I am trying to use whatsapp business api for my application with twilio. I already have read the documentation of whatsapp business api. My question is, can we use twilio to send the messages to different whatsapp group based on id. For example, If I have 3 groups such as Students, Professors, Assistants and based on each different group I want to send a specific message such as Hi to Students, Hello to Professors and Hey to Assistants. What I know till now that Whatsapp differentiate everything with specific id, for instance, chat.whatsapp.com/DeUzzel9O13231

I also have worked with the twilio and whatsapp api where you can send a message from your twilio number to your whatsapp number like below

using System; using Twilio; using Twilio.Rest.Api.V2010.Account; class Program  {     static void Main(string[] args)     {         // Find your Account Sid and Token at twilio.com/console         // DANGER! This is insecure. See http://twil.io/secure         const string accountSid = "ACXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXX";         const string authToken = "your_auth_token";         TwilioClient.Init(accountSid, authToken);         var message = MessageResource.Create(             body: "Join Earth's mightiest heroes. Like Kevin Bacon.",             from: new Twilio.Types.PhoneNumber("+15017122661"),             to: new Twilio.Types.PhoneNumber("+15558675310")         );         Console.WriteLine(message.Sid);     } } 

The code above is only for sending a message to a specific number. Can I do the same thing with the groups? If yes, How? Is there any documentation for that?

Thanks.

I am trying to connect my WhatsApp Business Account with Facebook so that it shows my business name. As per https://www.facebook.com/business/help/2087193751603668?helpref=faq_content there shall be an option for WhatsApp Account in business.facebook.com under 'Business Settings' > Accounts. But it is not there. It also says:

If the WhatsApp accounts option is not visible, the Business API may not be available to you yet.

So can anyone guide how to get Business API access?

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.

I want to Send a Text message or Image or any documents through Whatsapp using my grails application. Is there any solution ?

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 ?
