How to get your API key
An API Key can be "connected" to one specific event (can only access data of that event) or to an user account (can access all events of that user).
But the easiest ways to get your API key is by creating one in the frontend of your user account after logging in to your account on www.xing-events.com.
Create an API key with access for one event
Go to https://www.xing-events.com/mycenter/events.html, select the event you would like to have access to and create a new API key at the menu item "Edit Event -> Permissions".
Create an API key with access to all events of your account
Log in to the account you want to grant permission to, go to https://www.xing-events.com/mycenter/settings/apiKey.html,
or click on My Account.
Create a new API key with user permission in the API key tab.
