Video Generation Webhook
Quick Answer
Video generation APIs often use async jobs, polling or webhooks because video rendering takes time. Each polling request, webhook delivery, timeout resubmission and duplicate job creation can affect your cost review if not tracked properly.
What affects cost
Webhook and polling cost review covers job submission, status checks, webhook delivery attempts, timeout resubmission and whether the provider bills for polling or only for successful output.
Common billing units
- task for job submission
- poll if status checks are billed
- webhook if delivery attempts are tracked
- retry for duplicate or timed-out jobs
Cost risks
Impatient clients resubmitting after timeout, excessive polling without webhook fallback, webhook delivery failures causing retries, and assuming polling is free can all inflate video workflow costs.
Small test checklist
- Test webhook delivery vs. polling behavior
- Record job_id for every submission
- Check whether duplicate polling added to the bill
- Test timeout resubmission behavior
Common errors / failed tasks
Webhook endpoint not reachable, polling before job is ready, timeout resubmitting duplicate jobs and webhook retry storms are common failure modes. Use logs to track all delivery attempts.

Video generation webhooks and polling introduce cost variables that are easy to overlook: polling frequency, webhook delivery attempts, timeout resubmission and duplicate job creation.

Frequently Asked Questions
Is polling free?
Not always. Some providers bill for status checks, others include them in the job cost. Test to confirm.
Can webhook delivery failures add cost?
Yes, if retries or repeated delivery attempts are billed.
Should I use webhook or polling?
Webhooks generally reduce unnecessary polling, but both approaches should be tested for cost behavior with your provider.
