Format**: +- Detected before database queries +- Returns descriptive error message +- Example: "Invalid transaction ID format: expected UUID" + +**Invalid Parameters**: +- Dry-run flag must be boolean +- Limit must be positive integer (max 100) +- Offset must be non-negative integer +- Date ranges must be valid ISO 8601 timestamps + +**Batch Size Exceeded**: +- Maximum 1000 transaction IDs per batch +- Returns error: "Batch size exceeds maximum limit of 1000" + +### Authentication/Authorization Errors + +**HTTP 401 Unauthorized**: +- Missing authentication credentials +- Invalid or expired authentication token +- Returns: "Authentication required" + +**HTTP 403 Forbidden**: +- Valid authentication but insufficient privileges +- User lacks admin role +- Returns: "Administrator privileges required" + +### Resource Not Found Errors (HTTP 404) + +**Transaction Not Found**: +- Transaction ID doesn't exist in database +- Returns: "Transaction {id} not found" +- Applies to both single and batch replays +- In batch mode: marked as failed, processing continues + +### Business Logic Errors (HTTP 400) + +**Cannot Replay Completed Transaction**: +- Transaction status is 'completed' +- Replay requested with dry_run=false +- Returns: "Cannot replay completed transaction without dry-run mode" +- Rationale: Prevents accidental duplicate processing + +### Processing Errors (HTTP 500) + +**Database Errors**: +- Connection failures +- Query execution errors +- Transaction commit failures +- Returns: "Database error: {details}" +- Logged with full stack trace + +**Unexpected Errors**: +- Serialization failures +- Unexpected state conditions +- Returns: "Internal server error: {details}" +- Logged for debugging + +### Error Handling in Batch Operations + +Batch replays implement fail-safe error handling: + +1. **Individual Failure Isolation**: One failed replay doesn't abort the batch +2. **Detailed Error Reporting**: Each failed replay includes specific error message +3. **Summary Statistics**: Response includes total, successful, and failed counts +4. **Partial Success Support**: Batch can succeed partially (some pass, some fail) + +Example batch response with mixed results: +```json +{ + "total": 3, + "successful": 2, + "failed": 1, + "results": [ + { + "transaction_id": "uuid-1", + "success": true, + "message": "Webhook replayed successfully", + "dry_run": false, + "replayed_at": "2026-02-23T11:00:00Z" + }, + { + "transaction_id": "uuid-2", + "success": false, + "message": "Transaction uuid-2 not found", + "dry_run": false, + "replayed_at": null + }, + { + "transaction_id": "uuid-3", + "success": true, + "message": "Webhook replayed successfully", + "dry_run": false, + "replayed_at": "2026-02-23T11:00:01Z" + } + ] +} +``` + +### Error Logging and Observability + +All errors are logged with appropriate severity levels: + +**ERROR Level**: +- Database connection failures +- Unexpected processing errors +- Authentication/authorization failures + +**WARN Level**: +- Transaction not found (may be expected) +- Replay of completed transaction attempted +- Batch size limit exceeded + +**INFO Level**: +- Successful replay operations +- Dry-run executions +- Query operations + +Each log entry includes: +- Transaction ID (when applicable) +- Operator identity +- Error message and context +- Timestamp +- Request parameters + +### Retry and Recovery + +**No Automatic Retries**: Replay operations do not automatically retry on failure.
