Dolla provides a wrapper over Apple's app store receipt verification service in

  def deps do

  2. Ensure dolla is started before your application:

  def application do
    [applications: [:dolla]]
  3. If you're verifying receipts with recurring subscriptions, configure the
     secret in your dev.exs and prod.exs respectively
  config :dolla, :secret, "YOUR_SECRET"

## Usage

Once you have your base64 encoded receipt data (see [Apple's docs]( for more information), just pass them to `Dolla`.

iex> Dolla.verify("A MASSIVE BUNCH OF BASE64")
{:ok, %Dolla.Response{status: 0, receipt: %Dolla.Receipt{...}}...}

Dolla returns a tuple, so you're probably going to want to match on that. If you
get `:ok` as the first element in the tuple, then your receipt has successfully
