Data Sync
Data sync is the process of ensuring that data in two or more systems remains consistent, with changes made in one system reflected in others automatically or on a defined schedule.
Understanding Data Sync
Data sync is a foundational challenge in modern software. When a task is marked complete in your project manager, does that status reflect everywhere it's relevant? When a meeting is rescheduled in Google Calendar, does your Notion project page update? When a contact changes their email in your CRM, does your email tool reflect the change? Data sync is what makes these updates happen automatically. Sync architectures range from simple to complex. One-way sync (source → destination) is straightforward: changes in the source propagate to the destination. Bidirectional sync is harder: changes can originate in either system, creating the possibility of conflicts when both change simultaneously. Conflict resolution strategies include last-write-wins, source-wins, and human-reviewed merges. Sync frequency is another design decision: real-time sync (via webhooks) minimizes lag but creates more events to process; periodic sync (every 15 minutes, hourly, daily) batches changes but creates temporary inconsistency. The right cadence depends on how much staleness is acceptable. For AI assistants, data sync quality directly affects response accuracy. An AI that reports on a task list that's 2 hours out of date might surface completed items as pending or miss newly created ones.
How GAIA Uses Data Sync
GAIA maintains near-real-time sync with connected tools via webhooks and scheduled polling. When a task is updated in Linear or a calendar event is modified in Google Calendar, GAIA's state reflects the change quickly. This ensures that GAIA's responses about your tasks, emails, and calendar are based on current information rather than stale snapshots.

Webhook
A webhook is an HTTP callback mechanism where a system sends an automated HTTP request to a specified URL whenever a defined event occurs, enabling real-time notification and integration between services without polling.
API Integration
API integration is the process of connecting different software applications through their Application Programming Interfaces, enabling them to share data and functionality seamlessly.
Event-Driven Automation
Event-driven automation is a pattern where workflows are triggered automatically in response to specific events, such as a new email arriving, a calendar event being created, or a message being posted, enabling real-time, reactive processing.
REST API
A REST (Representational State Transfer) API is a web service interface that uses standard HTTP methods (GET, POST, PUT, DELETE, PATCH) to access and manipulate resources identified by URLs, following a set of architectural conventions that make APIs predictable and interoperable.
