Hello please send us your registered account email at hello@livecaller.io and we will give you all the necessary instructions + JWT code. We have a Javascript API for user authentication:

<script>
        // open widget window
        LiveCaller.$emit('ui.widget.open');

        // close widget window
        LiveCaller.$emit('ui.widget.close');

        // toggle widget window
        LiveCaller.$emit('ui.widget.toggle');

        // customer authorization
        LiveCaller.$emit('user.login', 'JWT Token Here');

        // customer profile editing
        LiveCaller.$emit('user.update', 'JWT Token Here');

        // change language after widget load
        LiveCaller.$emit('app.locale.update', 'ka');

        // change language before widget load
        LiveCaller.config.merge({app: {locale: 'ka'}});

        // Customer logout / session regeneration
        LiveCaller.$emit('user.logout');

        // Listen to the widget window open event
        LiveCaller.$on('ui.widget.open', () => {


        });

        // Listen to the widget window close event
        LiveCaller.$on('ui.widget.close', () => {

        });
</script>

for authentication and profile editing is used JWT
verification algorithm HS256
token lifetime is 15 minutes( can be changed from widget settings )
necessary payload information:
sub - unique id of the customer
iat - token generation timestamp ( UNIX timestamp seconds)

JWT Header example:

{
  "alg": "HS256",
  "typ": "JWT"
}

Edit Customer JWT Payload example:

{
  "sub": "12ba81b2-c1fe-479b-8b4a-09fecb02a3d6",
  "name": "John Doe",
  "email": "user@example.com",
  "mobile": "995000123456",
  "iat": 1565610612
