API Errors

Understanding WebScrapingAPI's HTTP response codes helps you identify the root cause of the errors you may encounter.

We have come across some instances of custom captchas that are being marked with a status code of 200, indicating a successful request. To ensure accurate billing and prevent any charges for these requests, it is necessary for us to mark them as 422. We kindly ask for your cooperation in reporting any encounters with custom captchas where the status code is 200. Your continued support is greatly appreciated. Thank you!
Below is a list of all the HTTP error codes you may encounter using the WebScrapingAPI:
