Documented steps
When starting POST /v2/crawl, add a webhook object to the body so you don't have to poll: {"webhook":{"url":"https://your.host/hook","headers":{},"metadata":{}}}.
webhook.url is required if you use the webhook feature; webhook.headers lets you pass auth tokens; webhook.metadata is echoed back into every payload for correlation.
Filter events with webhook.events (default all): 'started', 'page', 'completed', 'failed'.
You receive crawl.started once, crawl.page for EVERY scraped page (payload format is the same as the /scrape endpoint), then crawl.completed or crawl.failed.
Use the metadata/header you set to correlate the finished crawl back to your job.
Known gotchas
If you define a webhook, per-page events fire for every page crawled — on a large crawl this is a LOT of traffic; scope with webhook.events if you only need completion.
The crawler will not wait for your webhook to finish; it fires and moves on — handle idempotency/retries yourself.
With a webhook you can skip polling GET /crawl/{id} entirely, but you must still handle crawl.failed gracefully.
