# Check flight plan conflicts

`POST /flight-auths/check-conflicts`

## Request

- Base URL: `http://localhost:8486`
- URL: `http://localhost:8486/flight-auths/check-conflicts`
- Auth: API key in header `x-auth-token`

Analyzes a flight plan file for potential conflicts with existing flight authorizations without creating a new authorization

## Request body `multipart/form-data`

- object
  - `importingFile` string, binary, required: Flight plan file (JSON format) to analyze for conflicts
  - `flightStartTime` string, date-time, required: Flight start time in ISO-8601 format (e.g., 2024-01-15T10:00:00Z)
  - `flightEndTime` string, date-time, required: Flight end time in ISO-8601 format (e.g., 2024-01-15T12:00:00Z)
