store.init() for amazon kindle

I have this piece of code:

if store.availableStores.apple then  
 store.init("apple", transactionCallback)  
elseif store.availableStores.google then  
 store.init("google", transactionCallback)  
end  

now I want to add Amazon marketplace for Kindle
Do I have to call store.init like this:

store.init("amazon", transactionCallback)  

?
because the init keywords (apple, google, etc) are not documented in the API page for ‘store.init()’

Please help
