Hi there @RAMTAMANG !

It’s always possible that there could be a very short delay in a contact getting created in the API. This depends on a lot of different factors such as Network speed and how busy our servers are at the time. That said, I wouldn’t expect it to take too long to populate in the API -- depending on which call you’re making (Listing all and Search endpoints might take longer than a single User retrieval, for example). If you’re seeing a lot of time is needed then I would recommend you reach out to our support team directly either via your workspace Messenger or via email at team@intercom.io so they can look into this further with you!
