How paulprk/whatsapi-rest-php works

WhatsApi is a Slim 4 REST API for user accounts, authentication, two-person chats, and messages. Clients send JSON requests; the registered endpoint handlers validate inputs, enforce access rules, and use PDO-backed MySQL operations to return JSON results. The main workflow is authenticated users sending messages, which may create a chat, then listing chats or retrieving chat history; users can also manage profiles and admins can delete users or messages. The README documents additional endpoint behavior not fully visible in the sampled excerpts, so those capabilities are included without inferring finer internal call sequences.
