# Connect Talend with OAuth 2.0 (Client Credentials) – StackOne Hub

> Link a Talend account in the StackOne Hub using OAuth 2.0 (Client Credentials). End-user guide to authorize the integration and start using Talend actions.

> [!WARNING]
>
> Creating a service account requires the Service Account - Manage permission (TMC\_SERVICE\_ACCOUNT\_MANAGEMENT), which the Security Administrator role includes. It also requires a Talend Cloud subscription that includes the Talend Management Console — a Qlik Cloud Analytics-only plan or a free trial does not open the Management Console. The number of service accounts you can create depends on the Talend Cloud admin add-ons in your license (each admin add-on allows three service accounts).

## Creating a service account

A service account provides the OAuth 2.0 client credentials (a Client ID and Client Secret) that StackOne uses to authenticate with Talend Cloud.

**1. Sign in to Qlik Talend Cloud**

Sign in to your [Qlik Talend Cloud account](https://myqlik.qlik.com/tenants/index.html).

<ul>
  <li>To access the Talend Management Console, it is mandatory to migrate your Talend Cloud account to Qlik. If prompted, complete the migration wizard by clicking **Migrate your Talend account**, then sign in with your Qlik email and password.</li>
  <li>If you have multiple tenants, select your **Talend** tenant after you sign in.</li>
</ul>

**2. Open the Management Console**

Open the **Management Console** for your Talend Cloud account.

<ul>
  <li>Confirm the region host in your portal URL — for example, `https://app.eu.cloud.talend.com` is region EU.</li>
</ul>

**3. Open the Users & Security page**

In the Management Console, open **Users & Security** from the left navigation.

<ul>
  <li>Click the **Service accounts** tab.</li>
</ul>

**4. Create a service account**

Click **Create new**, then select **Service account**.

<ul>
  <li>Enter a name for the service account, for example `StackOne Integration`.</li>
  <li>Select the permissions the service account needs for your integration.</li>
  <li>Click **Save**.</li>
</ul>

**5. Copy the ID and secret**

After saving, a dialog displays the service account credentials.

<ul>
  <li>Copy the ID across to **Client ID**.</li>
  <li>Copy the secret across to **Client Secret**.</li>
  <li>The secret is displayed only once. Keep a copy — it is required to generate or renew tokens for this service account. If you lose it, you must renew the secret.</li>
</ul>

## Find your Talend region

Your Talend region identifies the Talend Cloud API endpoint StackOne calls for your tenant.

<ul>
  <li>Check your Talend portal URL while signed in — the region is the segment right after `app.`.</li>
  <li>Format: `https://app.{region}.cloud.talend.com`</li>
  <li>Example: if your URL is `https://app.sg.cloud.talend.com/portal`, your region is `sg` (Singapore).</li>
  <li>Select the matching value in the **Region** field in StackOne Hub.</li>
</ul>

## Link the Account

**1. 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>

**2. Use Actions**

Connect an AI platform to the linked account's actions. See [AI Platforms](https://docs.stackone.com/connect/ai-platforms/overview.md).

Other ways to call actions are listed in [Protocols & SDKs](https://docs.stackone.com/connect/protocols-and-sdks.md).
