External Services
This plugin connects to SnWebTech SMS Gateway Pro Bulk SMS, an external SMS service operated by SnWebTech.
Service website: https://snbulksms.in
The service is required for sending OTP messages. When a visitor requests an OTP, the plugin sends the recipient’s mobile number, OTP message content, sender information, DLT template information, and the configured API credentials to the service’s API endpoint. The plugin also connects to the service when an administrator uses the gateway balance check or test SMS tools.
The plugin uses these service endpoints:
* https://snbulksms.in/api/send.php — sends OTP/test SMS messages.
* https://snbulksms.in/api/balance.php — checks the account balance when requested by an administrator.
Please review the service provider’s own terms and privacy information before using the service.
