What is the InMobi secret key in AdMob Mediation network optimization?

Just upgraded my admob and I’m wanting to try the ad network optimization but don’t know what the Inmobi secret key is supposed to be set to. The other networks are fine because they only require your username and password. Anyone know what it is or where to find it?

Just send an email to InMobi helpdesk. They will give you the secret key.

Ok, thanks!

please give contact email to get secret key help me.

Would you please tell me the email id of the InMobi helpdesk? I am using InMobi on bestessays reviews website. So now I forget its username and password. So please help me to recover it.
