Constructor

ItunesReceiptDecoder.new expects the base64 encoded receipt as the first argument. There optional second argument defined as a hash, valid options are:

expand_timestamps: true : The timestamps included in the unified receipt are not in the same format as a validation from iTunes' servers. Use this option to expand the timestamps and reformat them in the same format as you would expect from a validation. e.g.

ItunesReceiptDecoder.new base64_encoded_receipt,
                         expand_timestamps: true

Methods and properties

ItunesReceiptDecoder.new will return either a ItunesReceiptDecoder::Decode::UnifiedReceipt or ItunesReceiptDecoder::Decode::TransactionReceipt instance. Both classes have the same public methods available:

#receipt : Returns the receipt properties as a Hash.

#environment : Returns the environment as a String.

#production? : True if the receipt was created in the Production environment.

#sandbox? : True if the receipt was not created in the Production environment.

#style : Either :transaction or :unified
