Promotions

Create Promotion

Creates a new promotion (discount offer or free trial) on the creator's profile. Promotions can target new subscribers, expired subscribers, or both (new_and_expired creates two OF-side promotions in one call). For free-trial **links** specifically, prefer the /v1/{account_id}/trial-links endpoints — this is the lower-level OF-native primitive. Requires permission api_promotions_create.
