Is there a way to bulk create licenses in the V3 API, other than just looping? I notice that the API is rate limited, which likely isn’t a major issue, but I often create licenses in batches of 50 for distributors and resellers, and V2 allowed me to do this in a single API call.
Bulk creation through a single call is not supported. You need a loop to bulk create the keys. The rate limit will allow you to create 50 license keys in parallel.
