# Prowl

Elixir application for sending notifications to [Prowl](https://www.prowlapp.com/).

## Installation

The package can be installed by following these steps:

  1. Add prowl to your list of dependencies in `mix.exs`:
```elixir
        def deps do
          [{:prowl, "~> 0.1.0"}]
        end
```
  2. Set your API key in your `config.exs`:
```elixir
        config :prowl, apikey: "your api key"
```
  3. Ensure prowl is started before your application:
```elixir
        def application do
          [applications: [:prowl]]
        end
```

## Usage

```elixir
iex> Prowl.notify(application, event, description, priority \\ 0, url \\ "")
{:ok, 988}
```

Sends a notification with the parameters given. Successful responses will come in the format above, where 988 is the number of api calls you have left (at the time of writing Prowl sets a limit of 1000 per hour).

The optional field priority can range from -2 to 2.

An optional URL can also be provided for the Prowl app to use to trigger a redirect.

## Errors

```elixir
iex> Prowl.notify(application, event, description, priority, url)
{:error, {error_code, error_message}}
```

If the API returns an error then the response will come in the format above. A list of possible error codes is given in the full API documentation.
