Developer Garden is Deutsche Telekom's developer platform.
Developer Garden provides APIs (Application Programming Interfaces) that allow developers to access core Telekom services such as conference call or messaging and integrate them into their applications.
we were able to load your picture and really don't know what the problem is. But we're working at it.
We'll immediatly post it here when we found the problem.
I have created an account at develper center.I have one query that if i acticate any API say conference call will i be charged .Means i want to test in mock and sandbox environment, so will activation of any API will cost me any price or it is free of cost.
it doesn't cost anything to activate any API. If you just use it in the sandbox and mock environment you also won't need to charge your account.
You will only have to pay for it if you use it in the production environment.
