This section documents framework-level subsystems that apply across every Commerce Connect implementation. Consult these articles when you extend the platform, configure cross-cutting behavior, or troubleshoot issues that span multiple subsystems.

## Application lifecycle

These articles describe when Commerce Connect code runs and how the system reacts to events at runtime.

- [Initialization system](docId\:WaLtn4F57XWvfvmxKCdY7) – Configure how Commerce Connect modules and dependencies start at application launch.
- [Events](docId\:XIGJV7jGzvCZQKigf3yPB) – Subscribe to notifications fired when prices, inventory, and other commerce data change.
- [Scheduled jobs (dev)](docId\:qY-hx7Av08-i-_6e-XgwA) – Author and configure background jobs for maintenance and batch processing.

## Request handling

These articles describe how Commerce Connect maps incoming requests to catalog content and serves responses efficiently.
