Whatsapp Third Party Client How To Use Messaging

On this blog, we will provide meaningful, concise and technical information directly from our developer team.

That changed with other messenger applications appearing on the stage, leading to the eventual adoption of end-to-end encryption using the Signal protocol.

Signal is still regarded as the most secure messaging protocol implementation to date by the cryptography community, with no currently known security flaws.

Thats because the API runs directly on the users backend To make this possible, Facebook provides a docker image that hosts both the user-facing REST API (which is a PHP application built on the Symfony framework, interestingly) and a proprietary, pre-compiled C backend service responsible for communicating with the actual WhatsApp servers.

Additionally, the container uses an external MySQL database for its storage.

Thats the exact same flow as for ordinary messages to other WhatsApp users (If youre looking for a good read, Moxie Marlinspike, the inventor of the Signal protocol, has explained this in great detail here ).

WhatsApp then resolves the recipients number to the current ACME Inc.

The message still encrypted is relayed to the ACME Docker container, where it is decrypted and stored for ACME, Inc.

Whats important here is that the Docker container that hosts the Business API really is just a slimmed-down WhatsApp client, just like the mobile app or, by extension, WhatsApp web, just with a REST interface instead of a GUI.

It also has its own set of private keys used for the message cryptography, and thus acts like a black box to both ACME, Inc.

Lets take a technical look into the API and define the working parts.

The PHP side of things is pretty standard after all, it validates input and proxies calls to the backend service via TCP sockets.

This is the only component we cannot analyze, since it uses encrypted connections exclusively.

Depending on how the network is structured, both might make sense: For instance, weve configured all containers to use our redundant WhatsApp database cluster.

This is the part business users need to implement by themselves.

To use the API in an actual product though, youd need to incorporate it in some sort of container cluster, taking care of security, redundancy, resource management and a lot more, of course.

At MessengerPeople, weve built a solid infrastructure around this, making it possible to use connectors for pretty much every common messenger app being able to expose a standardized interface for WhatsApp as well as iMessage, Facebook Messenger, Viber and Telegram is great.

After a few seconds, youll see that lovely Hello World notification popping up on your screen.

The API provides lots of other interesting capabilities well write about in future posts.

Companies offering messaging app customer service already have a clear competitive edge over companies with slower, old-fashioned service.
