Change Details
Understanding a change event and its components.
When Varen detects a change, it creates a change event with structured information to help you assess the impact and take action.
Anatomy of a change
Every change event includes:
| Field | Description |
|---|---|
| Description | A plain-English summary of what changed |
| Severity | One of 7 levels: Breaking, Deprecated, Removed, Added, Changed, Fixed, Cosmetic |
| Classification | The category of change (e.g., "Parameter removed", "Endpoint added") |
| Endpoint | The specific API endpoint affected, if applicable |
| Detected at | When Varen first detected the change |
| AI Analysis | For Tier 2 (AI-detected) changes, an explanation of the impact and suggested action |

AI analysis
For changes detected via AI (Tier 2), Varen provides:
- Impact assessment — how this change affects your integration
- Suggested action — what you should do in response
- Migration guidance — links to migration guides when available
Tier 1 changes (from OpenAPI specs) are detected deterministically and don't include AI analysis — the diff itself is the analysis.
