Hello again,

we are making progress with the API. But now I have another question.

If I try to change the value customer_client_start_mode via API (btapi.exe) I get an internal server error. 

My json file looks like this: 

If I remove the parameter for customer client start mode from the json file the API works. So it is not really a server error... I can change values like jump_group_id and name. But not the start mode of the customer client.

I guess this is the setting I can change in the console here (but only for a few clients at a time...):

Is there a way to change the value via API?
