# Crawlbase shows how to build a web scraping pipeline with Zapier using async callbacks

> Crawlbase published a guide explaining how to split web retrieval from Zapier's execution window by dispatching async crawls with a callback and catching the finished page in a second Zap.

## Briefing
- Crawlbase: Crawlbase published a guide explaining how to split web retrieval from Zapier's execution window by dispatching async crawls with a callback and catching the finished page in a second Zap.

## Why it matters
Zapier's finite execution window makes direct web scraping unreliable. By offloading the crawl to an async service with a callback, developers can build robust, event-driven extraction workflows without leaving the no-code automation ecosystem. This pattern is especially useful for teams that need to integrate scraping into broader business processes without custom infrastructure.

## Watch next
Will other scraping vendors add native Zapier integrations that handle async callbacks out of the box?
