+# Aadhaar Integration - ServiceNow Integration
+
+A **production-ready ServiceNow Script Include** for **Aadhaar verification** and **eKYC**, utilizing a **Connection & Credential Alias** for secure, secret-free integration.
+
+⚠️ **Compliance Warning:** Adherence to **UIDAI regulations**, the **IT Act**, **DPDP**, and your provider's terms is mandatory. Always obtain **explicit user consent** before performing any verification.
+
+---
+
+## 🎯 Key Features
+
+This script provides a complete flow for secure Aadhaar integration:
+
+| Feature                | Methods                    | Description                                                                      |
+| :--------------------- | :------------------------- | :------------------------------------------------------------------------------- |
+| **OTP eKYC Flow**      | `sendOtp()`, `verifyOtp()` | Multi-step process with built-in session management (expiry, replay protection). |
+| **Demographic Check**  | `verifyDemographic()`      | Verify identity (Name, DOB, Gender) _without_ OTP. Returns a match score.        |
+| **Document Retrieval** | `getDocument()`            | Downloads Aadhaar XML/PDF (supports encrypted documents).                        |
+| **Status Tracking**    | `checkStatus()`            | Queries the status of any ongoing verification session.                          |
+
+### 🔒 Security & Compliance Built-in
+
+- **No Hardcoded Secrets:** Uses **Connection & Credential Alias** (`aadhaar_api`).
+- **Data Masking:** Hides Aadhaar/mobile numbers in logs (e.g., `XXXX-XXXX-1234`).
+- **Audit Logging:** Comprehensive logging of purpose, actor, consent, and outcome.
+- **Consent Tracking:** Persistent tracking of the user's consent statement and timestamp.
+
+---
+
+## 🛠️ Setup & Configuration
+
+1.  **Create Connection & Credential Alias:**
+
+    - **Name:** `aadhaar_api` (or your chosen alias).
+    - **Base URL:** Your provider's base endpoint (`https://api.provider.tld`).
+    - **Auth:** Configure credentials (API Key, OAuth, Basic) as per your provider.
+
+2.  **Configure Endpoints (In Script):** Map your provider's API paths inside the Script Include:
+    ```javascript
+    var endpoints = {
+      otpSend: "/aadhaar/otp/send",
+      otpVerify: "/aadhaar/otp/verify",
+      // ... and others
+    };
+    ```
+3.  **Set Timeouts & Retries:** Configure `timeoutMs` (default 8000) and `retries` (default 2) to manage reliability.
+
+---
+
+## 🚀 Usage Examples
+
+Use from a **Background Script** or any server-side logic:
+
+```javascript
+var sa = new SmartAadhaar();
+
+// 1. Send OTP & Get Session ID
+var s1 = sa.sendOtp({
+  uid: "123412341234",
+  purpose: "eKYC for onboarding",
+  consent: true,
+});
+
+// 2. Verify OTP (using session_id from s1)
+var s2 = sa.verifyOtp({
+  uid: "123412341234",
+  otp: "123456",
+  session_id: s1.data.session_id,
+});
+if (s2.ok) {
+  gs.info("eKYC success for: " + s2.data.name);
+}
+```
+
+## API Reference
+
+All methods return a normalized envelope:
+`{ ok:Boolean, code:Number, message:String, data:Object }`
+
+| Method                 | Purpose                   | Required Parameters            |
