+# Bambu Lab Preset Sync API Documentation
+
+This document describes the Bambu Lab cloud API endpoints for syncing slicer presets (filament, print process, and machine profiles) between Bambu Studio and the cloud.
+
+**Captured from:** Bambu Studio v2.4.0.70 with bambu_network_agent v02.04.00.58
+**Date:** 2025-12-08
+
+---
+
+## Authentication
+
+All API requests require authentication via Bearer token.
+
+### Required Headers
+
+```http
+Host: api.bambulab.com
+Authorization: Bearer <access_token>
+User-Agent: bambu_network_agent/02.04.00.58
+X-BBL-Client-Name: BambuStudio
+X-BBL-Client-Type: slicer
+X-BBL-Client-Version: 02.04.00.70
+X-BBL-Device-ID: <uuid>
+X-BBL-Language: en-US

+
+---
+
+## Endpoints
+
+### 1. Get User Profile
+
+```http
+GET /v1/user-service/my/profile
+```
+
+Returns user account information including UID.
+
+### 2. List All User Presets
+
+```http
+GET /v1/iot-service/api/slicer/setting?version={slicer_version}&public=false
+```
+
+**Parameters:**
+- `version`: Slicer version (e.g., `2.4.0.5`)
+- `public`: Set to `false` for user presets only
+
+**Response:** Returns a list of preset IDs that the user has synced to cloud.
+
+### 3. Get Individual Preset
+
+```http
+GET /v1/iot-service/api/slicer/setting/{preset_id}
+```
+
+**Response:**
+```json
+{
+    "message": "success",

+    "error": null,
+    "public": false,

+    "update_time": "2025-12-08 01:06:27",
+    "nickname": null,
+    "base_id": "GFSA00",

+    },
+    "filament_id": null
+}
+```
+

+
+## Preset ID Naming Convention
+
+Preset IDs follow a specific prefix pattern indicating the type:
+
+| Prefix | Type | Description |
+|--------|------|-------------|
+| `PPUS` | Print Process | Print/quality settings (layer height, speeds, infill, etc.) |
+| `PFUS` | Filament | Filament settings (temperatures, flow, pressure advance, etc.) |
+| `PMUS` | Printer/Machine | Machine settings (gcode, bed size, kinematics, etc.) |
+
+The suffix after the prefix is a unique hash identifier.
+
+**Examples:**
+- `PPUS1b03400426f57d` - Print process preset
+- `PFUS169056f3003bb4` - Filament preset
+- `PMUSbc396893c54df0` - Machine/printer preset
+
+---
+
+## Preset Response Schema
+
+### Common Fields
+
+| Field | Type | Description |
+|-------|------|-------------|
+| `message` | string | API response status ("success") |
+| `code` | int/null | Error code if any |
+| `error` | string/null | Error message if any |
+| `public` | boolean | Whether preset is publicly shared |
+| `version` | string | Preset version |
+| `type` | string | Preset type: "filament", "print", or "printer" |
+| `name` | string | Display name of the preset |
+| `update_time` | string | Last update timestamp (ISO format) |
+| `nickname` | string/null | Optional user-defined nickname |
+| `base_id` | string | Reference ID of the parent/base preset |
+| `setting` | object | Key-value pairs of customized settings |
+| `filament_id` | string/null | Bambu filament ID if applicable |
+
+### Setting Object
+
+The `setting` object contains **only the delta/modified values** from the parent preset. Key fields include:
+
+- `inherits`: Name of the parent preset this inherits from
+- `updated_time`: Unix timestamp of last modification
+- Other fields depend on preset type (see below)

+## Base ID Reference
+
+The `base_id` field references Bambu's internal preset database:
+
+| Prefix | Type |
+|--------|------|
+| `GF` | Generic Filament |
+| `GP` | Generic Print Process |
+| `GM` | Generic Machine |
+
+Examples:
+- `GFSA00` - Generic filament base
+- `GP136` - Generic print process base
+- `GM033` - Generic machine base (H2D)
+
+---
+
+## API Operations (Verified)
+
+### Create Preset
+
+```http
+POST /v1/iot-service/api/slicer/setting
+Content-Type: application/json
+
+{
+    "type": "filament",
+    "name": "My Custom PLA",
+    "version": "2.0.0.0",
+    "base_id": "GFSA00",
+    "setting": {
+        "inherits": "Bambu PLA Basic @BBL X1C",
+        "nozzle_temperature": "210,205",
+        "updated_time": "1733665800"
+    }
+}
+```
+
+**Required fields:**
+- `type`: "filament", "print", or "printer"
+- `name`: Display name
+- `version`: Version string (e.g., "2.0.0.0", "2.3.0.2")
+- `base_id`: Parent preset ID
+- `setting`: Object with modified values including `updated_time` (Unix timestamp)
+
+**Response:**
+```json
+{
+    "message": "success",
+    "code": null,
+    "error": null,
+    "setting_id": "PFUSe99f2ff04974b4",
+    "update_time": "2025-12-08 16:31:48"
+}
+```
+
+### Update Preset
+
+**Important:** The Bambu Cloud API does NOT support true updates via PUT/PATCH.
+
+- `PUT /v1/iot-service/api/slicer/setting/{preset_id}` returns **405 Method Not Allowed**
+- `PATCH /v1/iot-service/api/slicer/setting/{preset_id}` returns **500 Cloud database failed**
+
+**Workaround:** To "update" a preset:
+1. GET the existing preset details
+2. Merge your changes
+3. POST to create a new preset (returns new `setting_id`)
+4. DELETE the old preset
+
+This mimics how Bambu Studio handles preset updates.
+
+### Delete Preset
+
+```http
+DELETE /v1/iot-service/api/slicer/setting/{preset_id}
+```
+
+**Response:**
+```json
+{
+    "message": "success",
+    "code": null,
+    "error": null
+}
+```
+

+
+## Notes
+
+1. **Delta Storage**: Presets only store modified values from the parent, using the `inherits` field to reference the base preset.
+
+2. **Version Tracking**: The `updated_time` field (Unix timestamp) is used for sync conflict resolution.
+
+3. **Gcode Escaping**: Gcode fields use `\\n` for newlines within JSON strings.
+
+4. **Multi-value Fields**: Some fields like `nozzle_temperature` contain comma-separated values for different conditions.
+
+5. **Authentication**: The access token can be obtained via Bambu Lab OAuth flow or the `/v1/user-service/user/ticket/{code}` endpoint.
