Thanks, i figured out how to do immediate and scheduled "price drops" but now I'm having problems with scheduling future sales with ending drops. If i enter the post body with entries without a null start date (like the docs show, i even copy and pasted and updated my variables) I get an error about needing a null start date. If I try to do something like have an entry with a null start date (to make the current tier active) and two other entries where one is the start date of the sale and the start date of the sale end I get an error about not being able to use two null start states. One thing I was able to do was use the null start date to immediately trigger a scheduled sale but this is not what im looking for, i want to have a start date pushed out a few days. This is so frustrating that the doc examples themselves don't work. I've gotten over the fact that the API endpoint docs are completely useless but this page https://developer.apple.com/documentation/appstoreconnectapi/app_store/in-app_purchase/managing_in-app_purchases seems to be the most verbose and still doesnt have correct information. Has anyone figured out a way to schedule a tier update starting in the future and ending in the future?

Sorry but the above just is not helpful to find how to update a series of in-app purchases prices
