Is portia natively using crawlera or is there an integration between the 2?
By default Portia doesnt use Crawlera. One would need to subscribe to Crawlera and then enable it for the Project through the Addon settings (https://helpdesk.scrapinghub.com/solution/articles/22000200395-scrapy-cloud-addons) and then run the Portia Spider. Then the spider will use Crawlera while crawling.
