HTTP 429 - Too many requests

HTTP 429 - Too many requests

I'm trying to add multiple rows using v2 Creator API method https://www.zoho.com/creator/help/api/v2/add-records.html
Unfortunately after 100 requests (done in aprox. 20 seconds) I'm receiving response with HTTP code 429 Too many requests (which could be understandable). I'm expecting to have in the response, the status code 2955 with the message "You have reached your API call limit for a minute. Please try again after sometime" as described in https://www.zoho.com/creator/help/api/v2/status-codes.html. However, instead of that, I'm getting HTML page with some general information as shown below:
Page not found

The requested URL is not configured to be used.

  • Try checking your URL for typos.
  • Try checking your URL for invalid characters. If required, they must be encoded.
This seems for me to be a bug and, as a unexpected behavior, should be fixed or at least described in the documentation.
