API : Change account

Hello,

I’m not sure it doesn’t already exist, but when I look at your doc I don’t see it.

I allow my client to upgrade their account from my website. Exactly as I do for creating an ccount with your API, I’d like to automaticly update account with API.

And as I requested in a previous thread, it could be great to may upgrade account by using package, and not only by giving all account details to the API.

Thanks
Pascal
