Iab

Interface usage is quite simple:

• IAB.new(iabframework) -- initialize specified IAB framework

Available frameworks: 'amazon', 'google', 'ios'

• IAB:setUp(value1, value2, ..., valueN) -- provide all the keys/devids/appids/etc needed for the framework, which you will get in same order on Native part in Map object
• IAB:setProducts({internalId1 = "storeId1", internalId2 = "storeId2", ..., internalIdn = "storeIdn"}) -- provide list of products you will be using (key is your internal products id, value is store specific product id)
• IAB:setConsumables({"internalId1", "internalId2", ..., "internalIdn"}) -- which of your products are consumables, that people can buy many times (provide internal product ids)
• IAB:isAvailable() --check if IAB is available, raises event:
  • Event.AVAILABLE --iab is available
• IAB:requestProducts() --request information for products provided in setProducts method
  • Event.PRODUCTS_COMPLETE
    • event.productId
    • event.title
    • event.description
    • event.price
  • Event.PRODUCTS_ERROR
    • event.error
• IAB:purchase(prodId) --purchase product by providing your internal product id, raises two events:
  • Event.PURCHASE_COMPLETE
    • event.productId
    • event.receiptId
  • Event.PURCHASE_ERROR
    • event.error
• iab:restore() --raise purchase events for each previously purchases entitled (not consumed) items, raises two events:
  • Event.RESTORE_COMPLETE
  • Event.RESTORE_ERROR
    • event.error

Code example:

if not tv then
	pcall(function() require "iab" end)
