Is Nomsa secure?

Emails, SMSes and Telegram messages are not 100% secure. Users should be wary of putting sensitive information directly in your message body. Depending on the level of sensitivity, users can consider using recipient-specific, high-entropy links or requiring further authentication to see sensitive information.

Difference between the Web App and Programmatic APIs

Web App: Users can access Nomsa by going to https://nomsa.gov.kh . The web app has a user interface that allows users to send templated messages via campaigns.

Programmatic APIs: Users who manage their own systems could also call our APIs to send messages programmatically. In order to use this feature, you need to generate an API key from Settings in the Nomsa web app. You can find more by going to our API Guide here.
