## 1.4.0
### Add `Swoosh.ApiClient.Finch`
You can configure what API Client to use by setting the config. Swoosh comes with
`Swoosh.ApiClient.Hackney` and `Swoosh.ApiClient.Finch`
```elixir
config :swoosh, :api_client, MyAPIClient
```
It defaults to use `:hackney` with `Swoosh.ApiClient.Hackney`. To use `Finch`,
add the below config
```elixir
config :swoosh, :api_client, Swoosh.ApiClient.Finch
```
To use `Swoosh.ApiClient.Finch` you also need to start `Finch`, either in your
supervision tree
```elixir
children = [
{Finch, name: Swoosh.Finch}
]
```
or somehow manually, and very rarely dynamically
```elixir
Finch.start_link(name: Swoosh.Finch)
```
If a name different from `Swoosh.Finch` is used, or you want to use an existing
Finch instance, you can provide the name via the config.
```elixir
config :swoosh,
api_client: Swoosh.ApiClient.Finch,
finch_name: My.Custom.Name
```
