Getting started

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 http://localhost:3000
6. Try sending a message on WhatsApp.

Whatsapp Webhook

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.

Development

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