Is there a way where I can get the API Key for users so we can use it in external system because it affects the deal creator count
Welcome to the community @yasinhassanien 
Can you explain a bit more about the scenario? Especially on how it affects the count?
Also, are you trying to obtain the API key via API?
Hope you were able to get the issue resolved. Feel free to create a new topic if the issue still persists.
