Promo codes are case sensitive, so the promo code in the URL must match the code entered in the ticket type configuration.  For this reason, we recommend avoiding mixed case for the promo code in order to minimize any issues around capitalization.

In this example, the URL would need to be www.xyz.org/events/tickets&s_promoCode=OFFER1 in order to display the associated ticket type.

For more information on using promo codes, please see Using Promo Codes.
