Hi,
The Alipay plugin does not handle adaptive payments.
To make the alipay plugin work, you need an email, a partner id and a security code ; there is more than one single information.; so what you are asking is not possible.
But you can create one alipay payment method per vendor and let your vendors receive directly money thanks to their account.
Each vendor will have to set their account information (the email, partner id and security code).
You need to have the vendor limitation activated in your website if you want your vendors be able to be paid directly.
