Tebex validates the promotion
Sprytto sends a bounded code through the server-side basket route. Tebex decides whether it is valid, what it applies to and how totals change. Browser text is never treated as a discount calculation.
- Coupons, gift cards and creator codes use their distinct provider operations.
- The current basket capability stays in an HttpOnly same-site cookie.
- Public errors stay stable and do not reveal provider internals or whether another customer used a code.
Storefront setup
- Enable the reviewed cart or promotion component on the intended page.
- Localize its label, help text, success and failure messages.
- Test a valid, invalid, expired and ineligible code in Tebex sandbox or the approved test store.
- Verify the displayed total is the value returned by Tebex.
Operational safety
Create and retire promotion rules in Tebex. Do not publish live codes in templates, logs, analytics dimensions or support screenshots.
