To use Crawlera, we need to authenticate the Crawlera user. This authentication is done using Crawlera API key. This is different than the Scrapinghub API key.
Crawlera API key can be found in the Set up instruction page https://app.scrapinghub.com/o/project-id/crawlera/crawlerauser/setup?status=any
The API key will be given in the Set up page as below. In cases where there is suspicion of API keys being compromised, you can create new crawlera key by pressing "Generate New Crawlera Key".
If you are facing issues even after using correct API key, feel free to contact our Support team.
