HTTP Response code as 429 (statusText: 'Too Many Requests') when the rate of requests to an API exceeds the application's capability

Environment

SAP SuccessFactors Time Tracking
SAP SuccessFactors Time Tracking Clock in Clock out

Cause

The rate of requests to an API exceeds the application's capability

Resolution

There is a limit on the amount of API calls that can be made per day.
We provide batch provisioning of 1000 events together and allow only 300 such APIs in a day.
At the same time, the maximum number of time events for a user in a request should not exceed 200.

There is no way to extend these limits. Going over this limit generates the error: HTTP status code '429 - Too Many Requests'

Operation Type	Limit	Notes
Query page size	1000	You can retrieve upto 1000 time events with every API call.
API Quota	300 per day	You can make upto 300 API calls in a single day.
Rate limiter	10 API calls per minute	You can make upto 10 API calls per minute at the rate of 1 API call for every 6 seconds.
