get_env(atom(), any()) :: any()

Helper function for retrieving cielo environment values

Example

iex> Cielo.Utils.get_env(:random_value)
** (Cielo.ConfigError) missing config for :random_value
iex> Cielo.Utils.get_env(:random_value, "random")
"random"
iex> Application.put_env(:cielo, :random_value, "not-random")
...> value = Cielo.Utils.get_env(:random_value)
...> Application.delete_env(:cielo, :random_value)
...> value
"not-random"
iex> System.put_env("RANDOM", "not-random")
...> Application.put_env(:cielo, :system_value, {:system, "RANDOM"})
...> value = Cielo.Utils.get_env(:system_value)
...> System.delete_env("RANDOM")
...> value
"not-random"

Specs

get_env!(atom(), any()) :: any()

Helper function for retrieving cielo environment values, but will raise an exception if values are missing.

Example

iex> Cielo.Utils.get_env!(:random_value)
** (Cielo.ConfigError) missing config for :random_value
iex> Cielo.Utils.get_env!(:random_value, "random")
"random"
iex> Application.put_env(:cielo, :random_value, "not-random")
...> value = Cielo.Utils.get_env!(:random_value)
...> Application.delete_env(:cielo, :random_value)
...> value
"not-random"
iex> System.put_env("RANDOM", "not-random")
...> Application.put_env(:cielo, :system_value, {:system, "RANDOM"})
...> value = Cielo.Utils.get_env!(:system_value)
...> System.delete_env("RANDOM")
...> value
"not-random"

Convert cielo map response to atom keyed map.

Examples

iex> %{"MerchantOrderId" => "7c17771a-1b66-494f-bb73-517f236dc9fe"} |> map_from_cielo()
%{merchant_order_id: "7c17771a-1b66-494f-bb73-517f236dc9fe"}

iex> %{merchant_order_id: "7c17771a-1b66-494f-bb73-517f236dc9fe"} |> map_from_cielo()
%{merchant_order_id: "7c17771a-1b66-494f-bb73-517f236dc9fe"}

Convert atom keyed map for a Cielo's valid map.

Examples

iex> %{merchant_order_id: "7c17771a-1b66-494f-bb73-517f236dc9fe"} |> map_from_cielo()
%{"MerchantOrderId" => "7c17771a-1b66-494f-bb73-517f236dc9fe"}

iex> %{"MerchantOrderId" => "7c17771a-1b66-494f-bb73-517f236dc9fe"} |> map_from_cielo()
%{"MerchantOrderId" => "7c17771a-1b66-494f-bb73-517f236dc9fe"}

Specs

put_env(atom(), any()) :: :ok

Helper function for setting cielo application environment variables.

Example
