Why is the category or IAB result “retry”, “null” or “no channel returned” in the JSON response?

The target URL was requested the first time. To determine the website category can take a bit longer than determine keywords. 

Depending on the load of the system the result is mostly available within the next or the next few requests. Until the website category isn’t determined we show the message “retry”. In some cases, you get a “null” or “no channel returned” in the JSON response. 

These messages are deprecated and will be removed over time (self-cleaning process).

Depending on your use case it might make sense to wait a few seconds until the second request is made to get a proper result for the same URL. It might be available in another few milliseconds or seconds. We recommend waiting – if you do a one-time analysis of URLs – up to 90 seconds before the 2nd request to secure to get a full response.

For a specific URL bulk processing (one-time analysis) we can configure your API-Key.
