Steps to reproduce:

1. Install the media GLPI using notes provided by Zabbix : https://www.zabbix.com/integrations/glpi
2. Create a GLPI user as described in the documentation

Result:
When a problem appear we have an error message that tell missing app-token.

No created ticket in our GLPI instance.

Expected:
A ticket created in GLPI.

To have a working media I needed to add this in getAuthToken function (after line 32) :

request.addHeader('App-Token: ' + 'The GLPI app token');

I also needed to add this to request function (after line 80) :

request.addHeader('App-Token: ' + 'The GLPI app token'); 

Could you please add a macro and modify the script for this ? 

Best regards,
