SMS – Send a Single Message

Send a Single SMS

Send a single SMS from your application, CRM, website, or backend system using the Libwana.Net SMS API.

Before sending messages, get your API key from User Panel → Communication → API and keep it securely on your server.

Make sure you have an active plan, sufficient credits, and an active SMS gateway.

For Twilio, configure and activate your gateway under Gateway → SMS → API, including the required credentials and sender phone number.

Then select it as your preferred SMS API gateway under Communication → API.

If you need to send the message through a particular SMS gateway, include its Libwana.Net UID as gateway_identifier inside the contact object.

The gateway_identifier is the Libwana.Net gateway UID and is not a Twilio SID.

Using It With Your Application or CRM

Trigger the HTTPS request from your application's backend or workflow. Map your customer's phone number and message into the contact array.

Your application should prevent duplicate events, respect recipient consent, and handle API errors appropriately.

Check Message Status

After sending, use the returned message ID to check the SMS status.

Include your Api-key and Accept: application/json headers when checking the status.
