Description

Checkify for WooCommerce adds a privacy-first age verification gate to your WooCommerce shop. Customers scan a QR code with the Checkify app to prove their age before checkout.

Requires Checkify Connector and WooCommerce.

Features

Configurable minimum age from 10 to 110
Verified or High Assurance assurance levels (aligned with the Checkify app)
Gate scope: checkout only, cart + checkout, or entire storefront
Inline widget on cart/checkout or full-page gate for catalog protection
Restrict verification to selected product categories (for example Vape or Alcohol)
Optional skip for logged-in customers and shop-manager bypass
Classic checkout and WooCommerce Checkout block / Store API support
HPOS (custom order tables) compatible

How it works

Install and connect Checkify Connector with your Checkify Pass ID.
Activate Checkify for WooCommerce.
Configure minimum age, scope, and optional category restrictions under WooCommerce Checkify age gate.
Unverified customers see the Checkify QR widget and cannot complete checkout until verified.

Category-scoped gating

Leave all category checkboxes unchecked to require verification for every product. Select specific categories to gate only those products and carts that contain them. Products in unrestricted categories (for example a t-shirt) should not trigger the gate when categories are configured correctly.

External services

This plugin relies on Checkify Connector (required dependency) to connect your WordPress site to Checkify verification services.

Service used:

Checkify API: https://checkify.me
Checkify website: https://checkify.me

Data is sent to Checkify when a customer starts or completes age verification on your shop (via the Checkify Connector plugin). This plugin itself does not make separate API calls; it uses the Checkify Connector API and verification session already configured on your site.

The plugin may cause the following data to be sent to Checkify (through Checkify Connector):

Your WordPress site domain
A Checkify site identifier and installation identifier
The Checkify Pass identifier configured by the site administrator
Verification request identifiers and status tokens
Request timestamps
Cryptographic signatures used to authenticate the WordPress installation

Browser storage (via Checkify Connector):

Cookie: checkify_state_id (functional verification session binding)
sessionStorage: short-lived pending QR request state in the verification widget

Checkify privacy policy: https://checkify.me/privacy-policy

Checkify terms: https://checkify.me/terms_and_conditions

Installation

Install and activate WooCommerce.
Install Checkify (the Checkify Connector plugin): search for Checkify under Plugins Add New on the WordPress.org plugin directory, or upload the Checkify Connector ZIP from checkify.me/wordpress-integration#downloads if you use the standalone package.
Activate Checkify, connect your site, and save your Checkify Pass ID.
Install Checkify for WooCommerce via Plugins Add New, or upload the ZIP to /wp-content/plugins/checkify-for-woocommerce/.
Activate the plugin through the Plugins menu.
Go to WooCommerce Checkify age gate to configure age, scope, and categories.

FAQ

Do I need a Checkify business account?: Yes. Site connection is approved by a business owner scanning the connection QR in the Checkify app. Age verification uses a Checkify Pass configured for your connected site.
Which plugins are required?: WooCommerce must be installed and active. Checkify (Checkify Connector) is also required for the age gate to run. You can activate Checkify for WooCommerce before Checkify is ready; an admin notice will guide you to install or activate Checkify until it is active.
Where do I get Checkify (Checkify Connector)?: Install Checkify from the WordPress.org plugin directory via Plugins Add New, or download the Checkify Connector ZIP from checkify.me/wordpress-integration#downloads and upload it under Plugins Add New Upload Plugin. Both packages provide the same Connector functionality.
Does this work with WooCommerce block checkout?: Yes. The inline verification widget is injected into cart and checkout blocks, Place order is disabled until verification completes, and Store API checkout/add-to-cart requests are blocked when required.
Can I gate only alcohol or vape products?: Yes. Under Restricted categories, select the WooCommerce product categories that require age verification. Carts containing only products outside those categories can proceed without verification.
Does parent category selection include subcategories?: Yes. Selecting a parent category also applies to products assigned to child categories. Category matching uses the parent product for variable products.
What happens if no categories are selected?: Verification is required for every product in the cart. Check the Status panel on the settings page — it should list how many categories are selected, not “All products (no category filter)”.
Does this plugin store customer identity data in WordPress?: No. Verification results are stored locally as a short-lived session (browser cookie and server transient) by Checkify. Your shop receives an age verification result, not passport or ID images.
Is WooCommerce HPOS supported?: Yes. The plugin declares compatibility with WooCommerce custom order tables (HPOS).
