# Require ID Before Checkout

> Configure Enterprise document verification on the cart and the optional Shopify Plus checkout backstop.

# Require ID Before Checkout

## What does this do for me?

This flow holds the cart's Checkout action until the customer completes a document-backed identity and age check. It is implemented for Enterprise stores with the age gate enabled, Enhanced mode selected, the checkout requirement turned on, and the identity provider configured on the server.

## 1. Turn on the server-side requirement

1. Open **Settings** in Age Verification.
2. Confirm that the current plan is **Enterprise**.
3. Under **General**, enable age verification and choose **Enhanced (provider-hosted document check)**.
4. Under **Enhanced verification**, enable **Require ID verification before checkout**.
5. Select **Save**.

If the server is missing the identity-provider configuration, Settings displays a critical warning and the public gate falls back to simple mode. Checkout enforcement also remains off so customers are not blocked with no working verification path.

## 2. Add the cart block

1. Open the theme editor for the cart template.
2. In the cart section that contains the Checkout button, add **Verify ID for checkout**.
3. Place the block directly above the Checkout button.
4. Leave **Hold the Checkout button until verified** enabled.
5. Save the theme.

The cart block is the primary enforcement surface. While enforcement is active and no live pass exists, it displays **Verify my ID** and intercepts cart and drawer checkout actions. If the app cannot return its status, the block hides and does not hold checkout.

## 3. Add the Shopify Plus backstop

Checkout-step UI extensions render only on Shopify Plus. On a Plus store:

1. Go to **Settings → Checkout → Customize**.
2. Add the **Age & ID Checkout Gate** app block.
3. Allow the app to block progress under Checkout behavior.
4. Save the checkout customization.

This checkout block is defense in depth. The cart block remains the primary surface across Shopify store plans, while the checkout block adds a second check on Plus. The app's own Enterprise entitlement is still required for either surface to enforce document verification.

## What the customer sees

The customer selects **Verify my ID**, completes the provider flow, and the cart block polls the webhook-backed status. It changes to **Verified!** only after the stored verification state is verified. Logged-in customers can reuse a live customer verification flag; guests use a verification ID and timestamp stored on the cart.
