# Connect Zapier with OAuth 2.0 - Client Credentials – StackOne Hub

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

> [!WARNING]
>
> Client credentials are only available after your integration is published as a public integration in Zapier's App Directory. StackOne requests the app access token with the `promotions:write` scope, which is only documented for Zapier partners, so the token request, and with it this connection, will likely fail for an integration that is not a Zapier partner.

## Copy the client credentials

Sign in to the [Zapier Developer Platform](https://developer.zapier.com/), open your integration and go to **Embed** > **Settings** > **Credentials**. Copy the **Client ID** and **Client Secret** across. Regenerating the client secret invalidates the previous one.

## OAuth scope

StackOne exchanges the client credentials for an app access token with the `promotions:write` scope, which [Delete promotion enrollment](https://docs.zapier.com/powered-by-zapier/api-reference/promotions/delete-enrollment) requires. You do not need to enter scopes. Endpoints that need a user access token, such as Zaps and action runs, are not available with this connection; use the OAuth 2.0 connection for them.

## 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).
