Does Wan 3.0 Support Webhooks?

Overview

Do not promise Wan 3.0 webhook support unless the current WaveSpeedAI endpoint documents callbacks for your account and route. The verified baseline for this batch is an asynchronous prediction flow where the app submits a task and polls the result endpoint for terminal status.

Build polling as the reliable path first. Store the prediction id, poll with backoff, stop at completed, failed, cancelled, timeout, or deleted, and expose clear user states while the video is running. This protects the product even if webhook behavior is unavailable, account-specific, or later changed.

If webhooks are available in your current route, treat them as a delivery optimization rather than the only source of truth. Verify signatures if provided, make handlers idempotent, retry safely, and keep a reconciliation poll for missed callbacks. Video jobs are expensive enough that duplicate completion handling matters.

WaveSpeedAI can still be a good Wan 3.0 integration surface without webhooks if the polling workflow is clean. For documentation, say “check current endpoint support” instead of advertising callbacks as a universal feature. That wording keeps developers from building against an unverified platform promise.
