  description: 'The Frihet REST API provides programmatic access to your business data

    in Frihet, the AI-native business management platform for modern businesses. ## Authentication


    All API requests require an API key passed via the `X-API-Key` header. Generate keys from **Settings > API Keys** in the Frihet app. ```

    X-API-Key: fri_your_api_key_here

    ```


    ### API-key scopes


    A key without scopes (no list, or an empty one) is unrestricted. A key with a

    non-empty scope list gets only what the list grants. On such a key, every

    request other than `GET` and `HEAD` needs the `write` scope (or `*`), except

    the read-only `POST /v1/gestoria/aging` and the POS and purchase-order routes,

    which check their own `pos:` and `purchase-orders:` scopes. E-invoicing endpoints need an `einvoice:` scope,

    and the sends (`einvoice/export`, `face/submit`, `ticketbai/submit`) also need

    `write` or `einvoice:write`. A request without the scope it needs gets

    `403 Forbidden` with a `detail` naming that scope. The refusal happens before

    the idempotency gate, so it does not reserve the `Idempotency-Key`. `GET /v1/permissions/me` reports `denied.write`, `denied.einvoice` and

    `denied.einvoiceSend` for the calling key. Inventory (`/v1/inventory/*`) and purchase-order (`/v1/purchase-orders/*`) routes are

    not released yet: after the scope checks they answer `503` with code

    `INVENTORY_AUTHORITY_NOT_RELEASED`, before the idempotency gate. ## Rate Limiting


    The API enforces a rate limit of **100 requests per minute** per API key. When exceeded, the API returns `429 Too Many Requests` with an integer

    delta-seconds `Retry-After` header and matching `retryAfter` JSON field. Every authenticated response includes rate limit headers:


    | Header | Description |

    |--------|-------------|

    | `X-RateLimit-Limit` | Maximum requests per window (100) |

    | `X-RateLimit-Remaining` | Remaining requests in current window |

    | `X-RateLimit-Reset` | Unix timestamp (seconds) when the window resets |

    | `Retry-After` | Integer seconds until the window resets (429 responses) |


    ## Idempotency


    Most POST requests accept an `Idempotency-Key` header to prevent duplicate

    resource creation from network retries. For protected routes, the key is

    reserved against the operation *before* the request is executed, and it stays

    reserved for 24 hours unless released by an explicit pre-write refusal. ```

    Idempotency-Key: 550e8400-e29b-41d4-a716-446655440000

    ```


    Keys must be at most 64 characters. We recommend UUID v4. A retry of the same operation gets one of three answers:


    | Situation | Response |

    |---|---|

    | The first request finished | The **original status and body**, verbatim, with `X-Idempotent-Replayed: true` |

    | The first request is still running, or its outcome could not be recorded | `409 IDEMPOTENCY_REQUEST_IN_PROGRESS` |

    | The key is live but was used for a **different** operation | `409 IDEMPOTENCY_KEY_REUSED` — the second operation is not executed |


    The replayed status is the **stored** one. A `201` replays as `201`, not `200`. This includes stored error responses: a request that answered `4xx` or `5xx`

    replays that same status and body, it does not re-execute — except explicit

    pre-mutation refusals on `POST /v1/pos/cash-sessions/{id}/close` (`503` when

    the workspace POS money-authority grant is not enabled and `403 POS_INACTIVE`

    before the POS app is activated), which release the reservation instead of

    caching the refusal for 24 hours. ### When a retry is refused


    A `409 IDEMPOTENCY_REQUEST_IN_PROGRESS` after the first request already

    returned means the outcome could not be recorded — the response was too large

    or unserializable, or the bookkeeping write failed. The API refuses rather than

    execute a second time, because for a fiscal document a duplicate is not

    recoverable. **Reconcile; do not simply retry with a fresh key.** Read the resource back

    (`GET` the collection, or look for the document the operation would have

    created) and decide from its actual state.'
