Intergrate PayPal for in-app purchases legal in GP?

Somebody told me that GP will ban your app if you integrate PayPal to pay for in-app purchases instead of Google Wallet. I am searching on Google for evidence but can’t find almost anything concrete.
Can someone send me evidence of this?

Thanks

Impossible, wrong policy

Here Quoting from Google Developer Policy
“App purchases: Developers charging for apps and downloads from Google Play must do so by using Google Play’s payment system.
In-app purchases:
Developers offering virtual goods or currencies within a game downloaded from Google Play must use Google Play’s in-app billing service as the method of payment.
Developers offering additional content, services or functionality within another category of app downloaded from Google Play must use Google Play’s in-app billing service as the method of payment, except:
where payment is primarily for physical goods or services (e.g., buying movie tickets, or buying a publication where the price also includes a hard copy subscription); or
where payment is for digital content or goods that may be consumed outside of the app itself (e.g., buying songs that can be played on other music players).”

and if its credits for a voip app for example?

Aren’t they dropping the Google Wallet?

In a simple word the user who pay the money to unlock the feature within your app is coming under "With in your app " section.

If your selling digital goods, Service offered out side your app like cab service, digital downloads like mp4 which is not related to your app then these will come under “outside your app” section.

Inside app - Google wallet payment only
Outside app - Third party allowed like PayPal.
