## Summary

You can use products from your Merchant Center product feeds in Google Ads
Shopping campaigns by linking your Merchant Center account to Google Ads. You
can do this manually in the [Merchant Center](https://merchants.google.com) or
automatically through the Merchant API.

## Manual steps

> [!CAUTION]
> Caution: Before starting the process, check your access level:
>
> - You must have the "Admin" role set in the Merchant Center to send the linking request.
> - You must have "Administrative Access" to approve Merchant Center linking requests in Google Ads.

Here are the steps to link your accounts from the Merchant Center:

1. Click the gear icon.
2. Click **Linked accounts**.
3. Click **Link account** , then enter the [Google Ads customer ID](https://support.google.com/google-ads/answer/1704344) for the account you want to link.
4. Click **Send link request**. This sends a request to the Google Ads account.

## Automatic steps

2. Use the \[`AccountAdsLink`\] resource in your call to [`accounts.insert`](https://developers.google.com/shopping-content/reference/rest/v2.1/accounts/insert) to create a new merchant account that's linked to your Google Ads account.

Existing merchant accounts

1. Use your Google Ads customer ID as the \[`adId`\] field of an \[`AccountAdsLink`\] resource.
2. Use the \[`AccountAdsLink`\] resource in your call to \[`accounts.update`\] with an existing merchant account ID to link your Google Ads account to the existing merchant account.
