Reference

The complete API surface, models, and operational details.

Call every resource through the scoped client from january.forUser(...). The optional endUserId fields on request models exist only for direct calls on the unscoped client, and the scoped client overwrites them.

• Client and resources: constructors, the token provider types, and each resource's operations.

• Foods API: food requests, responses, and the portion helper.

• Restaurants and food analysis API: restaurant search, food analysis, and the native scanner.

• Logs and glucose API: food, water, and weight logs, and glucose prediction.

• Models and enums: identifiers, enum constants, and model fields.

• Retries and token lifecycle: token caching, refresh, and backoff.

• Error handling: JanuaryException, error categories, and cancellation.

• Compatibility and permissions: requirements, bundled libraries, and manifest permissions.

• Testing and support: testing your integration, updating, and reporting issues.

• Troubleshooting: common build and runtime failures.

• Changelog: changes in each release.
