We found the most relevant help response for: Task Approval
A task can be rejected if the submission does not follow instructions, is incomplete, contains incorrect details, or does not meet the required quality bar.
A task is a small job posted by a campaign owner — such as an app install, review, signup, or survey — that a worker completes in exchange for a reward once approved.
You can usually cancel a task before final submission; once submitted for review, it must go through the normal approval or dispute process.
