# Entry

## Getting started with API

Interaction with the API works using POST or GET requests to the URL:

{% hint style="info" %}
<https://pay.skinout.gg/api/v1/\\><API METHOD>
{% endhint %}

Service accepts POST requests in JSON format with the header <mark style="background-color:blue;">"Content-Type: application/json"</mark>

### Authentication

All requests to the API must be signed using your API Key:

{% content-ref url="/pages/VUyUHwrRBUfgu27P2Rcd" %}
[Authentication](/en/sign.md)
{% endcontent-ref %}

### Response format

All service responses contain the <mark style="background-color:blue;">success</mark> parameter (can be <mark style="background-color:blue;">true</mark> or <mark style="background-color:blue;">false</mark>)

If <mark style="background-color:blue;">success = false</mark> , then the response will contain the <mark style="background-color:blue;">error</mark> parameter with the description of the error.
