Do we have webhook available for SAP successfactor?
Do we have any webhook available where I can get the notification if any operation happened in the entity like any object is inserted in the entity then I will get notification?
Yes, it is an inplace functionality called Intelligent Services (can be found in Successfactors within transaction "Intelligent Service Center (ISC)".
There you can subscribe to different events (only the one's provided in the standard, no custom hooks possible). The subscription results in an integration center flow, where data can be passed via different protocolls to a webservice of your choice.
You can also configure a "business rule" with an intelligent service as a starting point.
