Auto Activate on Payment - addons

[k.p.]

Hi,

 

I looked for a possibility to activate an addon automatically as soon as the client has paid. The documentation says that it is possible to auto activate the addon, and you only have to tick the field "Auto Activation on Payment" [1].

But when I create a new addon in WHMCS I couldn't find this field.

 

It is very important for my purpose to automatically activate addons, so I hope there is a way to manage this.

 

Thanks,

Karin

Update: Actually I found the announcement, that this feature is available in v4.1.0.
