# Introduction

Welcome to the Arkéa developer portal. Our Open Banking APIs let you assemble
account information, payment initiation, and PSD2 consent into your own products —
securely and in a few lines of code.

> **Info**
>
> This developer portal is a demo built with Fern. The API reference and partner
> guides are illustrative — the production Arkéa API is private and access is granted
> per partner agreement.

## What you can build

#### Account Information

Read accounts, balances, and transactions on behalf of consenting users (AIS).

#### Payment Initiation

Initiate SEPA and Instant Payment credit transfers from a Third Party Provider (PIS).

#### Consent Management

Create, track, and revoke PSD2 consents throughout their lifecycle.

## Your first request

Listing a customer's accounts, in the two SDKs Arkéa ships. The snippet is pulled
from the API Reference, so it tracks the spec, and `languages` limits the picker to
Python and TypeScript.

### Request

GET [https://api.getarkea.com/v1/accounts](https://api.getarkea.com/v1/accounts)

```curl
curl https://api.getarkea.com/v1/accounts \
     -H "consentId: cst_5f4e3d" \
     -H "Authorization: Bearer <token>"
```

```typescript
import { ArkeaClient } from "@arkea/sdk";

async function main() {
    const client = new ArkeaClient({
        token: "YOUR_TOKEN_HERE",
    });
    await client.accounts.listAccounts({
        consentId: "cst_5f4e3d",
    });
}
main();

```

```python
from arkea import Arkea

client = Arkea(
    token="YOUR_TOKEN_HERE",
)

client.accounts.list_accounts(
    consent_id="cst_5f4e3d",
)

```

```go
package main

import (
	"fmt"
	"net/http"
	"io"
)

func main() {

	url := "https://api.getarkea.com/v1/accounts"

	req, _ := http.NewRequest("GET", url, nil)

	req.Header.Add("consentId", "cst_5f4e3d")
	req.Header.Add("Authorization", "Bearer <token>")

	res, _ := http.DefaultClient.Do(req)

	defer res.Body.Close()
	body, _ := io.ReadAll(res.Body)

	fmt.Println(res)
	fmt.Println(string(body))

}
```

```ruby
require 'uri'
require 'net/http'

url = URI("https://api.getarkea.com/v1/accounts")

http = Net::HTTP.new(url.host, url.port)
http.use_ssl = true

request = Net::HTTP::Get.new(url)
request["consentId"] = 'cst_5f4e3d'
request["Authorization"] = 'Bearer <token>'

response = http.request(request)
puts response.read_body
```

```java
import com.mashape.unirest.http.HttpResponse;
import com.mashape.unirest.http.Unirest;

HttpResponse<String> response = Unirest.get("https://api.getarkea.com/v1/accounts")
  .header("consentId", "cst_5f4e3d")
  .header("Authorization", "Bearer <token>")
  .asString();
```

```php
<?php
require_once('vendor/autoload.php');

$client = new \GuzzleHttp\Client();

$response = $client->request('GET', 'https://api.getarkea.com/v1/accounts', [
  'headers' => [
    'Authorization' => 'Bearer <token>',
    'consentId' => 'cst_5f4e3d',
  ],
]);

echo $response->getBody();
```

```csharp
using RestSharp;

var client = new RestClient("https://api.getarkea.com/v1/accounts");
var request = new RestRequest(Method.GET);
request.AddHeader("consentId", "cst_5f4e3d");
request.AddHeader("Authorization", "Bearer <token>");
IRestResponse response = client.Execute(request);
```

```swift
import Foundation

let headers = [
  "consentId": "cst_5f4e3d",
  "Authorization": "Bearer <token>"
]

let request = NSMutableURLRequest(url: NSURL(string: "https://api.getarkea.com/v1/accounts")! as URL,
                                        cachePolicy: .useProtocolCachePolicy,
                                    timeoutInterval: 10.0)
request.httpMethod = "GET"
request.allHTTPHeaderFields = headers

let session = URLSession.shared
let dataTask = session.dataTask(with: request as URLRequest, completionHandler: { (data, response, error) -> Void in
  if (error != nil) {
    print(error as Any)
  } else {
    let httpResponse = response as? HTTPURLResponse
    print(httpResponse)
  }
})

dataTask.resume()
```

## Getting started

The [Get started](/open-banking/get-started) flow walks through the five steps from
browsing the catalog to your first authenticated sandbox call, and ends in the API
marketplace. For the underlying detail, read the
[Authentication](/open-banking/documentation/getting-started/authentication) guide and
the [PSD2 Overview](/open-banking/documentation/getting-started/psd2-overview).
