Hi @davaal,
Currently, the Express Checkout is only supported when using the plugin “WooCommerce Stripe Payment Gateway – By WooCommerce” for the payment methods.
If you are using a different plugin, please let me know which one and I’ll see if it is possible to add compatibility with it. Send me the link to the plugin page, if possible.
If you are using “WooCommerce Stripe Payment Gateway – By WooCommerce”, you need to enable the Google Pay and Apple Pay methods in the payment gateway settings, and the Express Checkout feature needs to be enabled on Fluid Checkout settings.
1. Go to WP Admin > WooCommerce > Settings > Payments.
2. Click the “Stripe – Credit Card (Stripe)” link on the payment gateways list to open the Stripe settings.
3. On the Stripe settings, mark the option “Payment Request Buttons > Enable Payment Request Buttons. (Apple Pay/Google Pay)”. Please note that Google Pay and Apple Pay options need to be enabled on your Stripe Dashboard settings for the Express Checkout feature to work on your website.
4. Go to WP Admin > WooCommerce > Settings > Fluid Checkout.
5. Check the option “Express checkout > Enable the express checkout section at checkout”.
Let me know how it goes.
Best,
Diego
