+# MSG91 Send OTP API Documentation Summary
+
+## Overview
+MSG91 provides an OTP service that allows sending One-Time Passwords (OTPs) via SMS, WhatsApp, and Voice calls. Channel selection and fallback behavior are configured inside the OTP Template created in the MSG91 control panel.
+
+---
+
+## 1. Send OTP Endpoint
+- **URL**: `https://control.msg91.com/api/v5/otp`
+- **HTTP Method**: `POST`
+
+---
+
+## 2. Headers
+| Header Name | Type | Required | Description |
+|---|---|---|---|
+| `authkey` | String | Yes | User authentication key (unique for every MSG91 user account). Can also be passed as query parameter. |
+| `content-type` | String | Yes | `application/json` (when passing JSON payload for template parameters). |
+
+---
+
+## 3. Query Parameters
+
+### Required Parameters
+| Parameter | Type | Description |
+|---|---|---|
+| `template_id` | String | OTP Template ID generated in the MSG91 Dashboard (OTP section). Configures the message template and delivery channels (SMS, WhatsApp, Voice). |
+| `mobile` | String | Recipient mobile number in international format with country code (e.g. `919876543210`). |
+| `authkey` | String | User authentication key. |
+
+### Optional Parameters
+| Parameter | Type | Default | Description |
+|---|---|---|---|
+| `otp` | String / Integer | Auto-generated | Custom OTP value to send. If omitted, MSG91 generates the OTP automatically. |
+| `unicode` | Integer | `0` | Pass `1` for non-English SMS content, `0` for English. |
+| `invisible` | Integer | `0` | Mobile App verification (1 = ON, 0 = OFF). Auto-verifies if mobile network is ON. |
+| `otp_expiry` | Integer | `15` | OTP expiry in minutes (Min: 1 min, Max: 10080 mins / 7 days). |
+| `otp_length` | Integer | `4` | Number of digits in generated OTP (Min: 4, Max: 9). |
+| `realTimeResponse` | Integer | - | Pass `1` to receive real-time API response handling error codes via caching. |
+
+---
+
+## 4. Request Body Parameters (JSON)
+- **Content-Type**: `application/json`
+- Pass dynamic variables defined in your MSG91 OTP template as JSON key-value pairs.
+- Variable names are **case-sensitive**.
+
+**Example JSON Payload**:
+```json
+{
+  "Param1": "Value1",
+  "Param2": "Value2",
+  "company_name": "MyCompany"
+}
+```
+
+---
+
+## 5. WhatsApp & Multi-Channel OTP Setup
+- **Template-Based Routing**: Delivery channels (SMS vs WhatsApp) are configured within the MSG91 Dashboard under the OTP Template (`template_id`).
+- When creating or editing an OTP template in MSG91, you can set WhatsApp as the primary or secondary fallback channel.
+- **Resend OTP API**:
+  - **Endpoint**: `GET https://control.msg91.com/api/v5/otp/retry`
+  - **Query Parameters**:
+    - `mobile`: Mobile number in international format.
+    - `authkey`: User authentication key.
+    - `retrytype`: Delivery type for resending OTP (`text` for SMS/WhatsApp text, `voice` for voice call; Default: `voice`).
