# Flylogs API

The Flylogs API provides programmatic access to your flight operations, crew management, training, safety, and billing data. It follows REST conventions and returns JSON responses.

## Base URL

```
https://fmc.flylogs.com/v1
```

## Authentication

All endpoints (except public ones) require an **API key** as a Bearer token in the `Authorization` header:

```
Authorization: Bearer flk_3pQ8XnX...Zr
```

API keys are long-lived, revocable secrets created by a Company Administrator under **Company Settings → API**. A key authenticates as the user it is bound to and inherits that user's permissions. There is no login step. See [API Keys](/fcom/api-docs/reference/api-keys.md) to create one, and [Authentication](/fcom/api-docs/reference/authentication.md) for how to send it.

## Request Format

| Method | Content-Type                                               |
| ------ | ---------------------------------------------------------- |
| GET    | No body — parameters in URL path                           |
| POST   | `application/json` (unless noted as `multipart/form-data`) |

## Response Format

All responses return JSON. Successful responses typically contain the requested data directly. Error responses include a `message` field:

```json
{
  "message": "Descriptive error message"
}
```

## HTTP Status Codes

| Code | Meaning                                 |
| ---- | --------------------------------------- |
| 200  | Success                                 |
| 400  | Bad request — invalid parameters        |
| 401  | Unauthorized — missing or invalid token |
| 403  | Forbidden — insufficient permissions    |
| 404  | Resource not found                      |
| 429  | Rate limited — too many requests        |

## Rate Limiting

API usage is throttled. Excessive requests will result in an automatic 14-day ban. Design your integration to cache responses and avoid unnecessary polling.
