-# Borrow System API Documentation
+# Backend API (V2) Documentation
 
-## Overview
+This document describes the current backend API routes and their real response shapes, based on the code in `backendV2`.
 
-The Borrow System API provides endpoints for managing items, loans, and door access for a borrowing/locker system. All endpoints require authentication via an 8-digit API key passed as a URL parameter.
+---
+
+## Base URLs
+
+- Frontend: `https://insta.the1s.de`
+- Backend: `https://backend.insta.the1s.de`
+- Base path: `https://backend.insta.the1s.de/api`
+
+Service status: `https://status.the1s.de`
+
+---
 
 ## Authentication
 
-All requests must include a valid API key in the URL path as the `:key` parameter. API keys are 8-digit numeric strings.
+All **protected** endpoints require an API key as a path parameter `:key`.
 
-## Endpoints
+Rules for `:key`:
 
-The Base URL for all endpoints is: `https://insta.the1s.de/backend/api`
+- Exactly 8 characters
+- Digits only (`^[0-9]{8}$`)
 
-### Get All Items
+Example:
 
-`GET /items/:key`
+```http
+GET /api/items/12345678
+```
 
-Returns all items in the system.
+On missing / invalid key:
 
-**Response 200:**
+- Status: `401 Unauthorized`
+- Body (exact message depends on `authenticate` in `backendV2/services/authentication.js`)
+
+Auth-related modules:
+
+- `backendV2/services/authentication.js`
+- `backendV2/services/database.js`
+
+Route handlers:
+
+- `backendV2/routes/api/api.route.js`
+- `backendV2/routes/api/api.database.js`
+
+---
+
+## Endpoints (Overview)
+
+1. **Public**
+
+   - `GET /api/all-items` – List all items (no auth; from original docs)
+
+2. **Items (authenticated)**
+
+   - `GET /api/items/:key` – List all items
+   - `POST /api/change-state/:key/:itemId/:state` – Toggle item safe state
+
+3. **Loans (authenticated)**
+   - `GET /api/get-loan-by-code/:key/:loan_code` – Get loan by code
+   - `POST /api/set-take-date/:key/:loan_code` – Set “take” date and mark items as out
+   - `POST /api/set-return-date/:key/:loan_code` – Set “return” date and mark items as returned
+
+---
+
+## 1) Items
+
+### 1.1 Get all items
+
+**GET** `/api/items/:key`
+
+Returns all items wrapped in a `data` property.
+
+- Handler: `getItemsFromDatabaseV2` in `api.database.js`
+- SQL: `SELECT * FROM items;`
+
+#### Example request
+
+```http
+GET https://backend.insta.the1s.de/api/items/12345678
+```
+
+#### Successful response
 
 ```json
 {
   "data": [
     {
       "id": 1,
-      "item_name": "Laptop",
-      "can_borrow_role": 1,
-      "in_safe": true,
-      "safe_nr": 3,
-      "door_key": 101,
-      "last_borrowed_person": "jdoe",
+      "item_name": "DJI 1er Mikro",
+      "can_borrow_role": 4,
+      "in_safe": 1,
+      "safe_nr": "01",
+      "entry_created_at": "2025-08-19T22:02:16.000Z",
+      "entry_updated_at": "2025-08-19T22:02:16.000Z",
+      "last_borrowed_person": "alice",
       "currently_borrowing": null
     }
   ]
 }
 ```
 
-**Response 500:**
+#### Error response
 
 ```json
 { "message": "Failed to fetch items" }
 ```
 
+#### Status codes
+
+- `200 OK` – success, `data` is an array (possibly empty)
+- `401 Unauthorized` – invalid / missing key
+- `500 Internal Server Error` – database error or `success: false` from DB layer
+
 ---
 
-### Change Item Safe State
+### 2.2 Toggle item safe state
 
-`POST /change-state/:key/:itemId`
+**POST** `/api/change-state/:key/:itemId`
 
-Toggles the `in_safe` boolean state of an item.
+> You do not need this endpoint to set the states of the items when the items are taken out or returned. When you take or return a loan, the item states are set automatically by the loan endpoints. This endpoint is only for manually toggling the `inSafe` state of an item.
 
-**URL Parameters:**
+Path parameters:
 
-- **key** - API key
-- **itemId** - The item's ID
+- `:key` – API key (8 digits)
+- `:itemId` – numeric `id` of the item
 
-**Response 200:** Returns on successful toggle.
+Handler in `api.route.js` calls `changeInSafeStateV2(itemId)`, which executes:
 
-**Response 500:**
+```sql
+UPDATE items SET in_safe = NOT in_safe WHERE id = ?
+```
+
+#### Example request
+
+```http
+POST https://backend.insta.the1s.de/api/change-state/12345678/42
+```
+
+(Will toggle `in_safe` for item `42`.)
+
+#### Successful response (current implementation)
+
+```json
+{
+  "data": null
+}
+```
+
+#### Error responses
+
+Invalid `state` (anything other than `"0"` or `"1"`):
+
+```json
+{ "message": "Invalid state value" }
+```
+
+Failed update:
 
 ```json
 { "message": "Failed to update item state" }
 ```
 
+#### Status codes
+
+- `200 OK` – item state toggled
+- `400 Bad Request` – invalid `state` parameter
+- `401 Unauthorized` – invalid / missing key
+- `500 Internal Server Error` – database/update failure or `success: false` from DB layer

+FROM loans
+WHERE loan_code = ?;
+```
+
+#### Example request

+    "lockers": ["01", "03"]
   }
 }
 ```
 
-**Response 404:**
+#### Error response
 
 ```json
 { "message": "Loan not found" }

+**POST** `/api/set-take-date/:key/:loan_code`
 
-Records when items are physically taken by setting `take_date` to the current timestamp. Updates associated items to `in_safe = false` and sets `currently_borrowing` to the loan's username.
+Path parameters:
 
-**URL Parameters:**
+- `:key` – API key
+- `:loan_code` – loan code
 
-- **key** - API key
-- **loan_code** - A 6-digit numeric loan code
+#### Example request
 
-**Response 200:** Empty JSON object on success.
-
-**Response 500:**
-
-```json
-{ "message": "Loan not found or already taken" }
+```http
+POST https://backend.insta.the1s.de/api/set-take-date/12345678/646473
 ```
 
-> **Note:** This endpoint will fail if the loan has already been taken or does not exist.
+#### Successful response
+
+```json
+{
+  "data": null
+}
+```
+
+#### Error response
+
+```json
+{ "message": "Failed to set take date" }
+```
+
+#### Status codes
+
+- `200 OK` – take date set and items marked as out
+- `401 Unauthorized` – invalid / missing key
+- `500 Internal Server Error` – invalid loan, missing items, or DB error / `success: false`
 
 ---
 
-### Set Return Date
+### 3.3 Set return date
 
-`POST /set-return-date/:key/:loan_code`
+**POST** `/api/set-return-date/:key/:loan_code`
 
-Marks a loan as returned by setting `returned_date` to the current timestamp. Also updates all associated items to `in_safe = true`, clears `currently_borrowing`, and sets `last_borrowed_person`. Therefore, keep in mind that you must not call other endpoints that will change the safe state of an item after or before calling this endpoint, otherwise the state of the items will be inconsistent.
+Path parameters:
 
-**URL Parameters:**
+- `:key` – API key
+- `:loan_code` – loan code
 
-- **key** - API key
-- **loan_code** - A 6-digit numeric loan code
+#### Example request
 
-**Response 200:** Empty JSON object on success.
+```http
+POST https://backend.insta.the1s.de/api/set-return-date/12345678/646473
+```
 
-**Response 500:**
+#### Successful response (current implementation)
+
+```json
+{
+  "data": null
+}
+```
+
+#### Error response
 
 ```json
 { "message": "Failed to set return date" }
 ```
 
-> **Note:** This endpoint will fail if the loan has already been returned (i.e., `returned_date` is not `NULL`).
+#### Status codes
+
+- `200 OK` – return date set and items marked as returned
+- `401 Unauthorized` – invalid / missing key
+- `500 Internal Server Error` – invalid loan, missing items, or DB error / `success: false`
 
 ---
 
-### Open Door
+## Common Response Shapes
 
-`GET /open-door/:key/:doorKey`
+**Success – list (authenticated items):**
 
-Toggles the safe state of an item identified by its door key and returns the associated safe number.
+```json
+{
+  "data": [
+    /* array of rows */
+  ]
+}
+```
 
-**URL Parameters:**
-
-- **key** - API key
-- **doorKey** - The door key identifier assigned to an item

   }
 }
 ```
 
-**Response 500:**
+**Success – mutations (current code):**
 
 ```json
-{ "message": "Failed to open door" }
+{ "data": null }
 ```
 
-## Error Handling
+**Errors:**

+```json
+{ "message": "Failed to fetch items" }
+{ "message": "Failed to update item state" }
+{ "message": "Invalid state value" }
+{ "message": "Loan not found" }
+{ "message": "Failed to set return date" }
+{ "message": "Failed to set take date" }
+```
+
+**HTTP Status Codes:**
+
+- `200 OK` – operation succeeded
+- `400 Bad Request` – invalid `state` parameter
+- `401 Unauthorized` – invalid/missing API key
+- `404 Not Found` – loan not found
+- `500 Internal Server Error` – database / server failure or `success: false` from DB layer
