+- Reverse proxy configurations
+
+**Configured In:**

+### Creating a User for API Access on A10 vThunder
+
+This guide explains how to create a user on A10 vThunder for API (AXAPI) access with appropriate privileges.
+
+#### Step-by-Step Instructions
+
+1. **Enter configuration mode:**
+   ```bash
+   configure terminal
+   ```
+
+2. **Create the user and set a password:**
+   ```bash
+   admin apiuser password yourStrongPassword
+   ```
+
+   Replace `apiuser` with the desired username, and `yourStrongPassword` with a secure password.
+
+3. **Assign necessary privileges:**
+   ```bash
+   privilege read
+   privilege write
+   privilege partition-enable-disable
+   privilege partition-read
+   privilege partition-write
+   ```
+
+   These privileges grant the user:
+   - Global read and write access
+   - Per-partition read and write access
+   - Permission to enable or disable partitions
+
+4. **(Optional) Enable external health monitor privilege (if needed):**
+   ```bash
+   privilege hm
+   ```
+
+5. **Exit user configuration:**
+   ```bash
+   exit
+   ```
+
+#### Notes
+
+- This user will now be able to authenticate and perform actions via A10's AXAPI (v2/v3) interface.
+- Role-Based Access (RBA) and partition assignment can further fine-tune access control.
+
+#### Example Login via AXAPI
+
+Example using `curl` for AXAPI v3 login:
+```bash
+curl -X POST https://<vThunder-IP>/axapi/v3/auth \
+  -d '{"credentials":{"username":"apiuser","password":"yourStrongPassword"}}' \
+  -H "Content-Type: application/json"
+```
