What is a WABA Instance?
WABA instance, is a colloquial term used by Unifonic to represent the hosted service of the Whatsapp Business API Client.
In order for you to access the Whatsapp service via API, WhatsApp requires the WhatsApp Business API Client to be installed and maintained according to Meta guidelines. As an official WhatsApp Business Solutions Provider - Unifonic will do this installation, hosting and maintenance on behalf of our customers.
When this WABA instance is up and running, the hosted service can communicate with WA servers in an end-to-end-encrypted manner, preventing malicious users from accessing this information.
What is the Whatsapp Business API client?
The WhatsApp Business API Client consists of a set of Docker containers, as well as database and media volumes which stores the media files that you send or receive.
A WhatsApp Business API Client consists of the following components:
- WebApp - handles authentication and authorization of API requests before passing it to the CoreApp
- CoreApp - receives Rest API requests from the WebApp, and sends encrypted messages to the WhatsApp server. It also receives incoming messages from the WhatsApp server, before sending it to Unifonic via the webhook server. It also downloads and saves media to the media volume.
- Database - persists data such as messages, contacts, configurations.
- Media volume - persists media data that is sent or delivered.
- Webhook server - receives incoming http messages before dispatching to Unifonic's subscribed endpoints.
How is the message sent?
Messages are encrypted between the WhatsApp app on a user’s smartphone through the WhatsApp infrastructure / data centers until it reaches our WABA Instance. It is only then that the decryption of messages will takes place.
After you sent an outbound message through the Unifonic Whatsapp API, the messages are processed to our Unifonic Business Layer before it is sent to the WABA Instance where it gets encrypted and dispatched into the WhatsApp infrastructure and finally pushed to the targeted device, where it is decrypted again.
