This means you've sent enough API Requests within the last hour (which is calculated from :00 - :00 e.g. 8:00- 9:00) to surpass your limit or hit a warning. API requests are all REST API requests excluding token requests.
There are three types of apiRequest limit you can hit
- apiRequests.hourly.warning - when you reach 80% of your pre-paid quota.
- apiRequests.hourly.soft - when your pre-paid quota has been exceeded.
- apiRequests.hourly.hard - when the hard limit on the account has been exceeded. You will now be blocked from sending API requests until the end of the hour.
