Now wildcard redirects will preserve URL query parameters through the redirect. For example, if there's a wildcard redirect setup for:
/p/*
→ /products/*
A visitor to the wildcard redirect would be redirected like so:
https://myshopify.com/p/summer-hat?promo_code=SUMMER2024
→ https://myshopify.com/products/summer-hat?promo_code=SUMMER2024
Preserving the values in the URL that come after the question mark can help for user attribution or for promotions.
