This library is a Rails application example of using the Ruby Whatsapp SDK library to communicate between a Web application with Whatsapp. This application lets you send Whatsapp messages and view them on the Web.

1. Clone this repository.
2. Run bundle install.
3. Run the server bundle exec rails s
4. Modify the access token in the whatsapp_sdk initializer. Note that if you change the file you have to restart the server since the file lives under initializers.
5. Open the web application in your browser https://localhost:3000
6. Try sending a message on WhatsApp.

You can use webhooks to receive alerts when users communicate with your account. To do that, we need to start a service and an endpoint and tell Meta to ping that endpoint whenever a Meta event happens. See the Meta documentation for the list of events available.

1. Make sure that the gemfile is pointing to the right whatsapp_sdk version.
2. Run the server bundle exec rails s.
3. Run ngrok http 3000 Copy the ngrok address from the console e.g. https://1234-123-123-12-123.ngrok.io
4. Add the address to the config/environments/development.rb file.
5. Go to the Meta panel and subscribe to the webhook. You will need to paste the ngrok address in Meta.

This repository uses tailwind-css rails. To update the assets automatically, run rails tailwindcss:watch.
