User available in GUI can't be accessed over API

There’s an user in the intercom system. From GUI, it’s accessible over https://app.intercom.io/..../users/ URL. However, API can’t reach that user. What can be the reason?
I’ve tried getUser, getLead, getVisitor. No change, none of them works. Always contact not found message returns.

Hey @mozturk - would be great to get an example of the API call you’re making here. If you want to share the id you’re using to find them, either by messaging into Intercom or sending in a DM, then we can take a deeper look :+1:
