## Installation
If [available in Hex](https://hex.pm/docs/publish), the package can be installed
by adding `whatsapp_api` to your list of dependencies in `mix.exs`:
```elixir
def deps do
[
{:wax, "~> 0.4.2}
]
end
```
Setup default parser in `config.ex`
```elixir
config :whatsapp_api, parser: Whatsapp.Parser
```
## Using GenServer Auth
```elixir
defmodule MyApp.Application do
use Application
alias Whatsapp.Models.WhatsappProvider
# See https://hexdocs.pm/elixir/Application.html
# for more information on OTP Applications
def start(_type, _args) do
import Supervisor.Spec
children = [
worker(Whatsapp.Auth.Server, [[
%WhatsappProvider{
name: "My company",
url: "https://wa.io:9090/v1",
username: "username",
password: "password"
}
]])
]
opts = [strategy: :one_for_one, name: MyApp.Supervisor]
Supervisor.start_link(children, opts)
end
end
```
Now you can use the provider name to authenticate
```elixir
iex> %{"contacts" => [%{"wa_id" => wa_id}] = WhatsappApi.check("5566295500", "My company")
iex> message = MessageOutbound.new(to: wa_id, body: "Hi!")
iex> WhatsappApi.send(message, "My company")
```
## Without GenServer Auth
```elixir
iex> message = MessageOutbound.new(to: "wa_id", body: "Hi!")
iex> auth_header = [{"Authorization", "Bearer #{token}"}]
iex> Whatsapp.Api.Messages.send({"https://wa.io:9090/v1", auth_header, message)
```
