# Connect Adyen with OAuth 2.0 – StackOne Hub

> Link a Adyen account in the StackOne Hub using OAuth 2.0. End-user guide to authorize the integration and start using Adyen actions.

## Find your live URL prefix

Your live URL prefix identifies the live Checkout API endpoints of your Adyen company. Leave **Live URL Prefix** empty for Test connections.

**1. Copy the live URL prefix**

In the live Customer Area, expand **Developers** and click **API URLs**, then copy the prefix shown on that page.

<ul>
  <li>Format: `{random}-{CompanyName}`</li>
  <li>Example: `a1b2c3-AcmeCorp`</li>
  <li>Paste it into the **Live URL Prefix** field in StackOne Hub.</li>
</ul>

![The API URLs page explaining that the live environment uses a prefix for Checkout, Classic, Recurring, Payouts and BinLookup APIs](https://mintcdn.com/stackone-60/eTLrFzg-j9yjnxiV/connectors/adyen/images/oauth2-config-api-urls.png?fit=max\&auto=format\&n=eTLrFzg-j9yjnxiV\&q=85\&s=38bf85dde5a69ae96f0dac54b1b34b46)

## Webhooks

The **Native Webhook URL** field in StackOne Hub is filled in automatically after you connect. You only need it if you also set up Adyen webhooks for this account.

## Linking the Account from the Hub

**1. Navigate to the Hub**

Use one of the three [Linking Account Methods](https://docs.stackone.com/connect/managing-connectors/linking-accounts.md) to access the Hub.

**2. Fill out the fields**

Fill out the following fields using details from your provider:

<ul>
  <li>**Live URL Prefix** (Optional)</li>
</ul>

**3. Connect**

<ul>
  <li>Click **Connect**</li>
  <li>If applicable, the provider will redirect you to a sign-in or authorization page. Complete the provider's authorization flow.</li>
  <li>Once authorization is successful, you will see a confirmation popup</li>
</ul>

If the account linking is successful, you will see the newly linked account on your [Accounts](https://app.stackone.com/accounts) page.
