# NDC Elixir SDK
[](https://gitlab.com/AirGateway/ndc-ex-sdk/commits/master)
[](https://hex.pm/packages/ndc_ex_sdk)
## Introduction
This is an Elixir package that wrapps any NDC-compliant API.
It's host-agnostic and flexible through-configuration so that it can reach any NDC hosts with flexibility.
## Installation
If [available in Hex](https://hex.pm/docs/publish), the package can be installed as:
1. Add ndc_ex_sdk to your list of dependencies in `mix.exs`:
def deps do
[{:ndc_ex_sdk, "~> 0.0.1"}]
end
2. Ensure ndc_ex_sdk is started before your application:
def application do
[applications: [:ndc_ex_sdk]]
end
## Use
There are two different ways about how to use this package, all of them using the function NDCEx.request.
The common arguments for three interfaces are the next:
- *method*: It is the ndc request type, that must to be made (it expect to be an atom).
- *data*: It is the Elixir structure that must to be build into a XML document. It can be merge with many data from the provider or the consumer config.
1. **NDCEx.request/3** -> request(method, data, path) when is_bitstring(path). Where:
- *path*: It is the path to the provider config file. It must to be a string. It shouldn´t contain the name of the config file, only the route to the folder where the file is. Something like: "test/ndc_providers/#{String.upcase(System.get_env("PROVIDER"))}"
An example of this first way is the next:
NDCEx.request(:AirShopping, [AirShoppingRQ:[foo:"bar"]], "path_to/ndc_providers/WA")
2. **NDCEx.request/4** -> request(method, data, config_path, credentials) when is_bitstring(config_path) and is_list(credentials). Where:
- *config_path*: is the path to the provider config file. It must to be a string (it can be a data structure if the credentials is nil).
- *credentials*: is a list with many possible options. But a mandatory field is *consumers*, and it must to be a path to the folder where the consumer (per provider) must to be. I mean, that if there is a consumer called "B512", and we have a provider called "WA", we need to make a route like this: "initial_path/ndc_consumers/B512/WA"
This las way accept that credentials can be nil.
+First example:
NDCEx.request(:AirShopping, [AirShoppingRQ:[foo:bar]], "path_to/ndc_providers/WA", nil)
+Second example:
NDCEx.request(:AirShopping, [AirShoppingRQ:[foo:bar]], "path_to/ndc_providers/WA", [consumer: "initial_path/ndc_consumers/B512/WA"])
