Can I Cancel or Delete a MiniMax H3 API Task?

Overview

Many video APIs let you cancel a task that is still running and delete finished ones, but the exact behavior — and whether a cancel actually stops billing — depends on the provider, so confirm it in the current MiniMax H3 documentation before you rely on it. Do not assume a cancel is always free or instant, because that assumption can quietly cost you.

These controls matter for two reasons. Cost: cancelling a job you no longer need, such as one abandoned by a user who navigated away, can save the generation spend if the provider honors it before completion. Operations: deleting completed tasks keeps your task list and any stored results tidy, which helps a great deal when you are tracking many jobs across many users. Build both into your integration rather than treating them as afterthoughts, since a queue full of stale tasks is harder to reason about and can hide real problems behind noise.

Wire cancellation into your app’s own cancel action, so when a user backs out of a generation, your backend actually tells the provider to stop rather than letting the job finish and bill for output nobody will use.

Check whether a cancelled task still incurs any partial charge, because that single detail decides how aggressively cancellation actually protects your budget and whether it is worth wiring up everywhere or only in the obvious places.
