I change the json library in my config files

# config/config.exs
......
config :receipt_verifier, :json_library, Poison

But I'm getting this error.

** (UndefinedFunctionError) function Jason.encode!/1 is undefined (module Jason is not available)
    Jason.encode!(%{"receipt-data" => "BASE64_ENCODED_RECEIPT_DATA"})
    (receipt_verifier) lib/receipt_verifier/client.ex:36: ReceiptVerifier.Client.do_request/2
    (receipt_verifier) lib/receipt_verifier/client.ex:19: ReceiptVerifier.Client.request/2
    (receipt_verifier) lib/receipt_verifier.ex:87: ReceiptVerifier.do_verify/2

I see the latest response from apple store for a sandbox environment item purchase is as follows:

%{"receipt" => %{"bid" => "com.google.www", "bvrs" => "1",
    "is_in_intro_offer_period" => "false", "is_trial_period" => "false",
    "item_id" => "1322556240",
    "original_purchase_date" => "2017-12-22 18:16:14 Etc/GMT",
    "original_purchase_date_ms" => "1513262574202",
    "original_purchase_date_pst" => "2017-12-22 10:16:14 America/Los_Angeles",
    "original_transaction_id" => "1000020362025483",

    "unique_vendor_identifier" => "AAAAAAAA-4D7A-DDAD-9126-922A7A34FD72"},
  "status" => 0}

And it seems the parser is not able to handle this. Wondering if there's something that I can do? Thanks.

This warning is printed during use on Elixir v1.8.0:

warning: deprecated time unit: :milliseconds. A time unit should be :second, :millisecond, :microsecond, :nanosecond, or a positive integer

Looks like there's two places the code needs to be updated:

Since you have already specified Elixir v1.4+, you should not run into any backwards compatibility issues with just changing those to :millisecond.

Thanks for your work!

App Store server notifications now include refund notifications for all types of in-app purchases, including consumables, non-consumables, and non-renewing subscriptions. You can use this information to take action in response, let the user know of any benefit changes, and tell them how to resubscribe.

Hi there - after submitting a base64 encoded receipt string through your package, I get the following error.

** (FunctionClauseError) no function clause matching in ReceiptVerifier.Parser.parse_response/1

A response does come back which properly identifies the IAP i was trying to verify by original_transaction_id, original_purchase_date and several other fields. The status returns 0.

However, looking at the function clauses in parser.ex, it looks like the two fields that are missing from the response I get back are: latest_receipt & receipt

I have tried adding our shared secret, but get the same result. Any idea what might be the issue?

Thanks so much for the package!

Getting this error when verifying a receipt in sanbox:

{_, data} = ReceiptVerifier.verify(attrs["receipt-data"], env: :sandbox)

Got:

{:error,
{:failed_connect,
[
{:to_address, {'sandbox.itunes.apple.com', 443}},
{:inet, [:inet], {:tls_alert, 'handshake failure'}}
]}}

Terminal:
['TLS', 32, 'client', 58, 32, 73, 110, 32, 115, 116, 97, 116, 101, 32, 'hello', 32, 'received SERVER ALERT: Fatal - Handshake Failure', 10]

Apple had released brand new Server-Side APIs.

Maybe we need a new elixir library.
