Integration Support

The Calendar Sync Module provides seamless integration with Google, Apple, and Outlook calendars through REST APIs. This allows users to sync events between their local system and these calendar platforms.

OAuth Authentication

The module supports OAuth 2.0 for secure authentication with third-party calendar services. It handles token generation, refresh, and storage securely, ensuring compliance with API provider requirements.

Event Synchronization

Events can be synced in both directions (local to cloud and cloud to local). The module ensures that all events, including titles, descriptions, dates, and recurrence rules, are accurately mirrored across platforms.

Bulk Operations

The module supports bulk event operations, such as adding, updating, or deleting multiple events at once. This improves efficiency when dealing with large numbers of calendar entries.

Two-Way Sync

Two-way synchronization ensures that changes made on either the local system or the third-party calendar service are reflected in real-time. This eliminates data duplication and ensures consistency across platforms.

Calendar Subscriptions

The module allows users to subscribe to public or shared calendars without requiring direct access to the source account. This is useful for tracking events from shared calendars, such as team meetings or holidays.

Conflict Resolution

The module includes logic to handle conflicts when the same event exists on both local and cloud platforms with different details. It provides options to merge events, overwrite one version, or notify the user for manual resolution.

Frequency Scheduling

Users can set custom sync frequencies (e.g., hourly, daily, weekly) to control how often events are synced. This is useful for minimizing API calls while ensuring up-to-date calendar data.

Error Handling and Logging

The module includes robust error handling and logging mechanisms to track failed sync attempts, invalid tokens, or API rate limits. This helps in troubleshooting issues and maintaining reliable operation.

Custom Fields Support

The module supports custom fields for events, allowing developers to extend the functionality with additional metadata such as location details, event categories, or tags.

Metadata Management

The module stores metadata about each calendar sync operation, including success/failure status, timestamps, and error messages. This is useful for auditing and debugging purposes.

Rate Limiting

To avoid exceeding API rate limits imposed by third-party services, the module includes built-in rate limiting functionality that enforces quotas per service provider.

Event Status Tracking

The module tracks the sync status of each event (e.g., “synced,” “error,” “pending”). This provides developers with visibility into which events have been successfully synced and which ones require attention.
