Zillow Application Approval Process - What happens with the other applciations?

[Katarina Takahashi]

Hi, I'm a first time landlord. 

I have questions regarding the Zillow application process. I have approved an application and am expecting a deposit today. 

What happens with the other applications that I received once I close the listing? Am I supposed to actively select "Decline application" and a reason why? Or does the posting just close and that's it? 

Thank you in advance for your advice!
