What’s changing
After May 7, 2020, we will require you to provide an inventory_tier_id as part of your request for any ticket_classes you are creating or updating for a tiered event. This change will ensure that ticket classes will never exceed the defined inventory capacity for their tier. Tiered events allow event creators to assign tickets to separate inventory tiers.
If your integration is not updated by May 7th, responses for tickets for tiered events will fail with a field error message "ticket_classes.0.inventory_tier_id" “MISSING”.
