## **Overview**

The Shopify CMS Connector in Search Atlas can experience authentication failures when connecting Shopify for use with Content Genius. These failures are typically related to **OAuth** or **Client Credentials** authentication methods.

## **Common Authentication Errors**

When connecting Shopify to Search Atlas, authentication may fail due to issues with either the OAuth flow or the Client Credentials (legacy token) method. These are backend-side connection issues that require investigation by our engineering team.

## **What to Expect**

If your Shopify CMS Connector is failing to authenticate, the issue is likely occurring on the backend during the connection handshake between Search Atlas and Shopify. This is not something that can typically be resolved through the UI alone, and may require our team to review logs and connection state.

## **Information to Have Ready When Escalating**

To help our team diagnose and resolve the issue quickly, please have the following details available:

- Your Search Atlas **project name**
- Your **Shopify store URL** (e.g., your-store-name.myshopify.com)
- The **exact error message** you see when the authentication fails
- The **authentication method** you are attempting to use (OAuth or Client Credentials)
- The approximate **timestamp** of when the error occurred

## **Next Steps**

Once you have the above information ready, escalate to our team so we can investigate the backend connection and resolve the authentication failure.
