JWT

There are two ways of generating a JWT. You can use the function that exists on the Nexmo definition:

var Nexmo = require('nexmo');

var jwt = Nexmo.generateJwt('path/to/private.key', {application_id: APP_ID});

Or via a Nexmo instance where your supplied applicationId and privateKey credentials will be used:

var Nexmo = require('nexmo');

var nexmo = new Nexmo({
    apiKey: API_KEY,
    apiSecret: API_SECRET,
    applicationId: APP_ID,
    privateKey: PRIVATE_KEY_PATH,
  });

var jwt = nexmo.generateJwt();

Voice (Deprecated)

nexmo.voice.sendTTSMessage(<TO_NUMBER>,message,options,callback);

Send TTS Prompt With Capture

nexmo.sendTTSPromptWithCapture(<TO_NUMBER>,message,<MAX_DIGITS>, <BYE_TEXT>,options,callback);

Send TTS Prompt With Confirm

nexmo.voice.sendTTSPromptWithConfirm(<TO_NUMBER>, message ,<MAX_DIGITS>,'<PIN_CODE>',<BYE_TEXT>,<FAILED_TEXT>,options,callback);
