Messenger Messaging API Client

The `messaging-api-messenger` package offers a comprehensive, TypeScript-rewritten client for interacting with the Facebook Messenger Platform API, enabling developers to build sophisticated chatbots and integrate diverse messaging functionalities. As part of the larger `messaging-apis` monorepo by Yoctol, its current stable version is `1.1.0`. While the monorepo sees regular updates, specific feature additions for `messaging-api-messenger` are less frequent, with the last notable feature (persona support) in `v1.0.2` (September 2020) and a type fix in `v1.0.5` (April 2021). The library distinguishes itself through full TypeScript support, automatic `appsecret_proof` handling for enhanced Graph API security, and a robust error handling system leveraging `axios` and `axios-error`. It covers a wide range of Messenger Platform capabilities including the Send API (for text, attachments, templates, and quick replies), User Profile API, Messenger Profile API (for persistent menus and get started buttons), Handover Protocol, and Persona API.
