 # Borrow System API Documentation
 
-**Frontend:** https://insta.the1s.de  
+## Overview
-**Backend base URL:** `https://insta.the1s.de/backend/api`
 
----
+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.
 
 ## Authentication
 
-All API endpoints require **either**:
+All requests must include a valid API key in the URL path as the `:key` parameter. API keys are 8-digit numeric strings.
-
-### 1. Bearer Token (JWT)
-
-Send an `Authorization` header:
-
-```http
-Authorization: Bearer <JWT_TOKEN>
-```
-
-- Used for user-based access.
-- Token must be valid and not expired.
-
-### 2. API Key (for devices / machine-to-machine)
-
-Include an API key in the route as `:key` parameter:
-
-```text
-/api/.../:key/...
-```
-
-Example:
-
-```http
-GET /api/items/12345678
-```
-
-Where `12345678` is your API key.  
-The API key is validated server-side.
-
----
-
-## Common Response Codes
-
-- `200 OK` – Request was successful.
-- `401 Unauthorized` – Missing or malformed credentials.
-- `403 Forbidden` – Credentials invalid or not allowed to access this resource.
-- `404 Not Found` – Resource (e.g., loan) not found.
-- `500 Internal Server Error` – Unexpected server error.
-

----
+## Error Handling
 
-## Authentication Error Messages
+All endpoints return a `500` status code for server-side failures and a JSON body with a `message` field, except for **Get Loan by Code** which returns `404` when no matching loan is found.
-
-### Missing credentials
-
-Status: `401`
-
-```json
-{
-  "message": "Unauthorized"
-}
-```
-
-### Invalid JWT
-
-Status: `403`
-
-```json
-{
-  "message": "Present token invalid"
-}
-```
-
-### Invalid API Key
-
-Status: `403`
-
-```json
-{
-  "message": "API Key invalid"
-}
-```
-
----
-
-## Notes
-
-- All responses are JSON.
-- Time fields like `take_date` and `returned_date` are in the format returned by MySQL (usually ISO-like strings).
-- `loaned_items_id` in the database is stored as a JSON array string (e.g. `"[1,2,3]"`) and is parsed internally; clients do not interact with this field directly via current endpoints.

+# Changelog for upcoming version: v2.2
+
+This update provides some new features for the design. It also contains some improvements and I have also fixed some bugs.
+
+## New features
+
+- **Deactivatable services:** I have added the ability to deactivate services, which can be useful for maintenance or other purposes. The admin can activate and deactivate services in the admin panel. If a service is deactivated, it will not be available for users and they will get an error message if they try to use it. They will also get an warning banner on the homepage.
+- **New Animations:** I have added some new animations to the frontend, which make the user experience more enjoyable.
+- **New Icon:** I have added a new icon for the frontend, which is now also used in the header and the favicon. It is a dark version of the old icon, which fits better to the overall design. I have made it with Icon Composer. The old icon is still used for the admin panel, which has a light design. (Maybe I will change the admin panel design in the future...)
+- **New Button:** When you go to your user card (over the user icon in the header) you have a new button "Click me". If you click it, you will get an message... _I am just saying: I have implemented the no-as-a-service code in to my Backend._
+
+## Improvements
+
+- The overview page now shows the note column and is overall better organised.
+- Improved error logging
+- If you try to delete a loan that has not been returned yet, you will get an 507 error code.
+- When the admin deletes a loan, the loan will be still visible in the database, but it will be marked as deleted. This is to prevent data loss and to keep track of deleted loans.
+
+## Fixed bugs
+
+- Fixed bug: #13
+- Fixed bug for messaging when server has an error
+- Fixed footer height
+
+---
+
+## New version numbers
+
+**Backend:** v2.2
+
+**Frontend:** v2.2
+
+**Admin panel:** v1.4
