# NIC SMS Integration

## Overview

Integrate the NIC SMS Gateway for secure, DLT-compliant SMS delivery in DIGIT.

**Why use NIC SMS?**

* Secure (TLS 1.2 + certificate)
* DLT-compliant (template IDs)
* Government sender ID
* Customizable message parameters

## Steps

{% step %}

### Add NIC SMS Service Code

**File:** [`egov-notification-sms/src/main/java/org/egov/web/notification/sms/service/impl/NICSMSServiceImpl.java`](https://github.com/upyog/UPYOG/blob/master/core-services/egov-notification-sms/src/main/java/org/egov/web/notification/sms/service/impl/NICSMSServiceImpl.java)

* Create this file.
* Paste the NIC SMS integration Java class code.
* This code:
  * Sends SMS securely to NIC via HTTPS.
  * Handles DLT template IDs.
  * Uses SSL certificate for authentication.
    {% endstep %}

{% step %}

### Place the NIC Certificate

**File:** [`egov-notification-sms/src/main/resources/smsgwsmsgovin.cer`](https://github.com/upyog/UPYOG/tree/master/core-services/egov-notification-sms/src/main/resources)

* Put the NIC `.cer` certificate file here.
* Needed for a secure connection if `sms.verify.certificate=true`.
  {% endstep %}

{% step %}

### Update Environment Config

**File:** Your environment YAML file (like `values.yaml` or `dev.yaml`)

* Add/update these configs under `egov-notification-sms`:

  ```
  sms-provider-url: "https://smsgw.sms.gov.in/failsafe/MLink"
  sms.provider.class: "NIC"
  sms.verify.certificate: "true"
  sms.senderid: "IUPYOG"
  sms.provider.entityid: "1201160648389652723"
  sms.default.tmplid: "1"
  sms.enabled: "true"
  # ...other required parameters
  ```
* Ensure that only the NIC is active as the SMS provider.
  {% endstep %}

{% step %}

### Build & Deploy

* Run:

  ```
  mvn clean install
  ```
* Deploy the updated egov-notification-sms service to your environment (e.g., Kubernetes).
  {% endstep %}
  {% endstepper %}

### Summary - Checklist

* [x]  NIC SMS Java class added
* [x]  NIC certificate placed in resources
* [x]  Config updated in YAML
* [x]  Project built
* [x]  Service deployed
