Hi @saini3080
I wasn’t able to take a look at your site as a link wasn’t included, but a few things I would recommend checking.
1 – Make sure that your Stripe account is fully set up to accept Apple Pay. You will need to agree to the terms and conditions in Stripe. If you are unsure of if you’ve done this or how to do this, you can contact Stripe.
2 – Check to make sure that you’ve added your site’s URL as an accepted URL in Stripe for Apple Pay
The second and third errors you mentioned sound like they are being caused by third-party plugins or themes, as WooCommerce doesn’t have a captcha functionality by default.
For that, I would suggest some conflict testing to see if your theme or another third-party plugin is causing an issue. We have a guide on how to test for conflicts here:
https://docs.woocommerce.com/document/woocommerce-self-service-guide/#section-4
Since those tests will impact the look and functionality of your site, you may want to set up a staging site to try the tests on.
