One of our Client is using professional edition. Our requirement is customization in the standard object which uses apex classes and triggers. We identified that Professional edition does not support Apex class and triggers and the client is not willing to upgrade it to Enterprise edition.

And if we purchase the RestAPI license can we deploy the Apex code in Professional Editon?

Also, we noted that the only way to deploy apex classes via managed packages. Is there any hack/Workarounds available? Quick responses are appreciated.

Thanks,
Nancy
