A chat API is an application program interface that provides access to a back-end chat service & server infrastructure with the stability and broad features required to easily embed real-time chat inside of your app at a scale suited to your needs from an intimate conversation to a very large chat group.
Chat API embraces countless use cases only limited by your imagination including ride sharing, delivery, marketplaces, communities, healthcare, education, sports, live streaming, and entertainment. It essentially allows you to implement live (sometimes asynchronous) chat and messaging within your own mobile application, website, game, or other service. It can open new customer support, and marketing channels as well as increase user engagement and retention. It emphasises the core strengths of your product. It empowers conversations.

Some Chat API vendors, including Sendbird, also provide a Voice API and Video API as well as part of their communication platform.
