# Interface: Logger

Defined in: [packages/b2c-tooling-sdk/src/logging/types.ts:73](https://github.com/SalesforceCommerceCloud/b2c-developer-tooling/blob/67fb8580ac3c5b372617ee3ec3fc8f2bc9f16174/packages/b2c-tooling-sdk/src/logging/types.ts#L73)

Logger interface for structured logging with support for multiple log levels.

Each log method supports two overloads:
- `method(message: string, context?: LogContext)` - message-first format
- `method(context: LogContext, message: string)` - context-first format for structured logging

Use [Logger.child](#child) to create a child logger with bound context that will be included in all subsequent log entries.
