+# Badge assignment API
+
+Use these endpoints from the **Badge Management → Badge Assignment** UI.
+
+## Authentication
+
+- Send **Authorization** header with a valid JWT.
+- The backend sets `requestor` on `req.body` from the token (you do not need to send it in the body).
+
+---
+
+## Option 1: Single user (one request per user)
+
+**PUT** `/api/badge/assign/:userId`
+
+- **URL:** Replace `:userId` with one user’s MongoDB ObjectId (e.g. `PUT /api/badge/assign/507f1f77bcf86cd799439011`).
+- **Body (JSON):**
+  ```json
+  {
+    "badgeCollection": [
+      { "badge": "<badgeId>", "count": 1, "featured": false }
+    ]
+  }
+  ```
+- **Success:** 201, body = user profile id.
+- **Errors:** 400 (bad request), 403 (forbidden), 500 (server error). Response body is a string message.
+
+To assign to **multiple users**, call this endpoint **once per user** with the same `badgeCollection`.
+
+---
+
+## Option 2: Bulk (multiple users in one request)
+
+**POST** `/api/badge/assign/bulk`
+
+- **Body (JSON):**
+  ```json
+  {
+    "userIds": ["<userId1>", "<userId2>"],
+    "badgeCollection": [
+      { "badge": "<badgeId>", "count": 1, "featured": false }
+    ]
+  }
+  ```
+- **Success:** 201, body = `{ "assigned": ["id1", "id2"], "failed": [] }`.
+- **Errors:** 400/403/500 with JSON `{ "error": "..." }`. Partial success still returns 201 with `assigned` and `failed` arrays.
+
+Use this when the UI sends **one request** with multiple selected users.
+
+---
+
+## Frontend checklist
+
+1. **URL**
+   - Single: `PUT /api/badge/assign/{userId}` (one call per user).
+   - Bulk: `POST /api/badge/assign/bulk` with `userIds` and `badgeCollection` in the body.
+
+2. **Headers**
+   - `Authorization: <JWT>`
+   - `Content-Type: application/json`
+
+3. **Body**
+   - Always send `badgeCollection` as an array of `{ badge, count, ... }`.
+   - For bulk, also send `userIds` as an array of user id strings.
+
+4. **Error handling**
+   - Do not show a generic “Oops” for every failure. Use the **response status** and **response body** (string or `error` field) to show a specific message (e.g. “User not found”, “Badge collection is required”).
+
+---
+
+## Debugging
+
+- Restart the backend after code changes.
+- In the **server console** you should see lines like:
+  - `[Badge Assign] PUT /badge/assign called. userId=...`
+  - or `[Badge Assign Bulk] POST /badge/assign/bulk called. userIds=...`
+- If you never see these when clicking Assign, the request is not reaching this API (check frontend URL and Network tab).
+- In the browser **Network** tab, inspect the failing request: URL, method, request payload, and response status/body.
