Does this require Wix's Velo (custom code) plan?

Yes, any custom Stripe logic beyond basic payment links requires a Velo-enabled plan.

Can we migrate away from Wix Payments without migrating the whole site?

Yes, the payment layer can typically be swapped independently of the rest of the site.

Stripe + Wix

Stripe Integration for Wix Sites

Custom Stripe logic via Wix Velo for stores outgrowing Wix Payments.

Wix's Velo platform allows custom backend code, which is what makes real Stripe integration possible beyond Wix's built-in payment options. We work within Wix's constraints to wire up Stripe correctly.

Wix's Velo platform is what makes a real Stripe integration possible on Wix at all: without Velo's custom backend code, you're limited to Wix's own built-in payment options, which don't support custom billing logic, Connect-style payouts, or anything beyond simple product/service payments.

Working Within Velo's Constraints

Any custom Stripe logic beyond basic Payment Links requires a Velo-enabled plan. This is a hard platform requirement, not a preference
Velo's backend code runs in a more constrained environment than a general-purpose server, which shapes how webhook handling and API calls are structured
The payment layer can typically be migrated away from Wix Payments independently of the rest of the site, if a future platform migration is on the roadmap
Testing webhook delivery specifically within Velo's execution model, since its constraints differ from a standard Node.js server environment

We work within Velo's actual constraints rather than assuming Wix behaves like a conventional hosting environment: the platform's limitations are real, and the integration design needs to account for them rather than discover them mid-build.
