Common API Structures

While the GroupMe API has many endpoints for interacting with groups, direct messages, and users, several common data structures appear consistently across all of them. Understanding these core structures is essential for building rich, interactive applications.

Messages are the lifeblood of the API, and they often contain more than just simple text. They can carry special objects that represent rich media, describe system-level occurrences, or encode custom emoji. This section provides detailed documentation on these fundamental building blocks.
