# `ExGram.Handler`
[🔗](https://github.com/rockneurotiko/ex_gram/blob/0.65.0/lib/ex_gram/handler.ex#L1)

Behaviour for handling updates in `ExGram.Bot` implementations.

Implement this behaviour in your bot module to handle incoming updates from Telegram.
The `c:handle/2` callback receives parsed messages and a context struct, while
`c:handle_error/1` handles any errors that occur during message processing.

See the [Handling Updates guide](handling-updates.md) for more details.
