Checkout on your domain directs customers to a secure, branded payment page using your website's URL (https://yourdomain.com/checkout). This creates a seamless, trustworthy purchasing experience without redirecting to external payment pages.

Requirements:

• Custom domain or subdomain (including Squarespace domains, transferred domains, linked domains, and subdomains)
• SSL enabled with "Secure" preference

For sites without custom domains, checkout uses integrated domains (example: https://iddasuaconta.squarespace.com/checkout).

Verifying Your Checkout Settings:

1. Navigate to Checkout Settings
2. Open the Checkout panel
3. Look for your custom domain under "Checkout on your domain"

Troubleshooting Common Issues:

If Checkout Shows Incorrect Domain:

• Test purchases while logged in may show integrated domain
• Use incognito window for accurate testing
• Check checkout settings if custom domain isn't appearing

If SSL Issues Occur:

1. Open Developer Tools
2. Select SSL
3. Set Security Preference to "Secure"

404 Errors After Checkout:

• Usually occurs when site is set to Private
• Set site to Public to resolve
• Note: Orders still process successfully despite 404 error

For integrated domains without customization, the checkout URL will default to the platform's standard format (yoursitename.squarespace.com/checkout).

This secure checkout solution maintains brand consistency while ensuring transaction security, creating a professional and trustworthy purchasing experience for your customers.
