Post to a Server
----------------

This program posts data to a service. [Full source][post_example].

```java
public static final MediaType JSON = MediaType.get("application/json");

OkHttpClient client = new OkHttpClient();

String post(String url, String json) throws IOException {
  RequestBody body = RequestBody.create(json, JSON);

The user of your API (an external developer) will create an invoice in your API with a POST request.

Then your API will (let's imagine):

* Send the invoice to some customer of the external developer.
* Collect the money.
* Send a notification back to the API user (the external developer).
    * This will be done by sending a POST request (from *your API*) to some *external API* provided by that external developer (this is the "callback").

O usuário da sua API (um desenvolvedor externo) criará uma fatura na sua API com um request POST.

Então sua API irá (vamos imaginar):

* Enviar a fatura para algum cliente do desenvolvedor externo.
* Coletar o dinheiro.
* Enviar a notificação de volta para o usuário da API (o desenvolvedor externo).
    * Isso será feito enviando um request POST (de *sua API*) para alguma *API externa* fornecida por esse desenvolvedor externo (este é o "callback").
