# Connect Klaviyo to Chatarmin

> Connect your Klaviyo account to Chatarmin with OAuth and configure consent property sync.

Connect Klaviyo to Chatarmin so contacts, properties, and activity stay in sync between WhatsApp marketing and your email CRM.

## When to use it

Use this setup when you want Chatarmin to read Klaviyo segments and lists, push WhatsApp opt-in status and other properties to Klaviyo profiles, or trigger WhatsApp flows from Klaviyo events and webhooks.

Open the connect page at [https://chatarmin.com/dashboard/klaviyo/connect](https://chatarmin.com/dashboard/klaviyo/connect).

## Connect with OAuth

Chatarmin connects to Klaviyo through OAuth. You sign in on Klaviyo’s site and approve the permissions Chatarmin needs.

**1. Start the connection**

On the Klaviyo connect page, click **Connect now**.

**2. Continue on Klaviyo**

Klaviyo opens in your browser. If you see a notice that the app has not been reviewed by Klaviyo’s partner team, click **Continue** when you started the connection from Chatarmin.

**3. Select your Klaviyo account**

Choose the Klaviyo account you want to link to Chatarmin, then click **Select**.

**4. Allow access**

Review the permissions and click **Allow**. You return to Chatarmin when the connection succeeds.

> [!TIP]
>
> After a successful connection, Chatarmin shows that you are connected to Klaviyo via OAuth.

## Configure property sync

After OAuth succeeds, configure how Chatarmin writes WhatsApp consent to Klaviyo:

1. Under **Automatic sync of properties**, keep **Sync chatarmin consent to property** enabled unless your team uses a different setup.
2. Confirm the Klaviyo custom property name (default: `chatarmin_whatsapp`).
3. Click **Save settings**.

These settings match the options on [the Klaviyo connect page](https://chatarmin.com/dashboard/klaviyo/connect). For what gets synced automatically and how to enrich profiles from flows, see [Klaviyo integration](/integrations/klaviyo/klaviyo-integration.md) and [How to update properties](/integrations/klaviyo/klaviyo-how-to-update-properties.md).

## Troubleshooting

> [!WARNING]
>
> **Missing subscription scope:** If Chatarmin shows that your Klaviyo connection is missing the required subscription scope, click **Reconnect** on the connect page and complete OAuth again so all features work.

If you still use a **Private API Key** connection, Chatarmin prompts you to switch to OAuth. Click **Re-connect now** and follow the same OAuth steps above. Private API keys are deprecated by Klaviyo; OAuth is the supported method going forward.

To remove the integration, click **Disconnect** on the connect page and confirm. See also [How to disconnect integrations](/integrations/how-to-disconnect-integrations.md).
