Must I use Google play billing library if i want to sell an ad space directly to advertisers?

I want to sell an ad space in my Android app that's on play store. I want to sell it directly to advertisers who will need to pick the target for their ads, Is it a must to use google play billing library to get payed for the adspace or i will be violating google play terms if i use another payment system. I went through this article https://play.google.com/about/monetization-ads/payments/ unfortunately it was not clear to me. Any help please.
No, Google Play Billing Library only supports selling digital goods and click-based ads.

ITunesConnect: 3rd person transactions?

I'm making a utility application for a photographer. He is going to (obviously) be taking pictures, but wants to charge people at an event for a handful of digital images emailed or shared on social media. In this situation i would have to use Paypal or Square SDKs and not in app purchasing because he is going to compose the transaction and not the customer buying the pictures. Sort of like a mini POS system. He can't pay himself with another's credentials - so it would have to be a 3rd party solution. right? Is this against Apple's guidelines?
Am I over thinking this?
If the intent is to support in-person / face to face (swipe) credit card or keyed in credit card payments, check out the PayPal Here SDKs for iOS and Android which are now available on the PayPal Developer site:
https://developer.paypal.com/webapps/developer/docs/integration/mobile/pph-sdk-overview/
There is also a version for Windows 8.1+ in Beta, available upon request. You can email DL-PayPal-Here-SDK#ebay.com for help with any of these.

Selling Books in an iOS App

I am working on an iOS project where the customer wants to sell hardcopy books in the application. I did this application using PayPal, but I don't think Apple will approve the PayPal user and the book will delivered to buyers by address. How can handle this? I want also to sell ebooks and I don't know how to handle that.
Thanks!
You should read the developer guidelines very carefully, but there doesn't seem to be any restriction against creating apps that sell physical goods. You can't use In-app Purchasing for that, but it doesn't sound like you want to anyway:

Is it against the rules to hand out gift codes for our game on the App Store?

After publishing an app on iTunes you get 50 promo codes to hand out to users. This usually runs out pretty quickly. We thought we may be able to circumvent this by gifting the app to certain users using a US iTunes gift card. Does anyone know if this is against the App Store policy in any way? I read through the terms and conditions and didn't see anything about it.
Thanks
Apple will get their 30% cut, so there should be no problem with that idea.
I think you're confusing gift cards and promo codes.
Gift cards are paid in advance using real money, so Apple gets 30% of the gift card value up front.
Apps bought using gift cards can receive customer reviews.
Promo codes are totally free, nobody earns anything.
Apps received using promo codes can not receive customer reviews.
You can't give away iTunes Gift Cards to promote your App. I wanted to do this on Twitter and Facebook to interact with the users, so I decided to contact Apple to make it all clear. Here is the reply:
Thanks for reaching out.
Unfortunately, iTunes Gift Cards, iTunes Codes or Apple product cannot be given out in conjunction with app promotions. That said, you’ll need to find an alternate incentive/gift for the program.
Best regards,

Platform or API to allow purchasing and payment to owner

I am looking for the easiest platform or API to integrate into my site that would allow users to sell goods and get paid for them. I would, of course, take a small percentage of the payment. Hoping for something that is usable from python, though php would work too.
You need split payments. I think only Paypal currently offers that.
