Help Verifying hooks

I am really new on Podio and I need help to  verify webhook.

 

I created a hook, and I get this url: https://podio.com/autanacrmcom/podio/hook

The status is Inactive. If I push "verify" button, I get this message: "Verification requested"

The thing is, I don't know how to verify it.

I am doing an integration through javascript.

 

Thank you very much,
