flutter user generated in app purchasing system like udemy - flutter

Im building an app which users can plan events and sell tickets. so i want to build a system which lets users define in app purchase products and sell it to other users and as apps owner i will cut my comission. My problem is users can't define in app purchase products and apple pay or G pay is unavailable in my country. When i bought a course from udemy on mobile, i saw the course was an in app purchase product. So how they do this and how can i do same in flutter? If this is not possible, are there any way to take users payment info just like in app purchase for send to endpoint?

You will need to use a 3D payment provider.
try integrating strip for example in your application

Is there a way to test Facebook Instant In-app Purchases without creating a Payment Account?

I'm developing an instant game for Facebook (Meta) which have in-game purchases. I'd want to implement in-game market feature.
As far as I can see, there are a three requirements for in-app purchases to work:
Upload at least one game bundle
Register at least one product
Create a payment account
I've done (1) and (2), but because I'm not a legal entity, I can't create a valid Payment Account for the app. Is there a way to test purchases without it?

How to use Apple in app purchase with WKWebView

I have an e-commerce App based on WebKit. I know apple will reject the app because it contains payments and we don't use there in app purchase.
so, my question is: is there any way to integrate in app purchase with the WebKit.
for example, once the user clicks on "buy" button, we may terminate the webView and presenting a view controller with payment details.
It looks like You don’t need in app purchase if you are offering consulting services.
3.1.3(d) Person-to-Person Services: If your app enables the purchase of real-time person-to-person services between two individuals (for example tutoring students, medical consultations, real estate tours, or fitness training), you may use purchase methods other than in-app purchase to collect those payments. One-to-few and one-to-many real-time services must use in-app purchase.

how to i implement Apple in-app Subscriptions in Flutter

I want to provide auto or even Manuel renewable subscription in my Flutter App for iOS devices. Users can subscribe for 1 Month or 1 year.
Which one is the best? How to implement? Are these secure?
i tired Square Plugin; but got this response from Apple
Guideline 3.1.1 - Business - Payments - In-App Purchase
We noticed that your app offers a subscription with a mechanism other
than the in-app purchase API.
Specifically, subscription to view digital content within the app.
Next Steps
To resolve this issue, please revise your app to ensure that the
subscription for products used within the app is offered using the
in-app purchase API, with the exception of the content specified in
guideline 3.1.3 of the App Store Review Guidelines.
and
In-App Purchase
It may be appropriate to revise your app to use the in-app purchase
API to provide content purchasing functionality.
In-app purchase provides several benefits, including:
The flexibility to support a variety of business models.
Impacting your app ranking by consolidating your sales to one app rather than distributing them across multiple apps.
An effective marketing vehicle to drive additional sales of new content.
For information on in-app purchase, please refer to the following
documentation:
In-App Purchase for Developers
In-App Purchase Programming Guide
For step-by-step instructions on in-app purchase creation within App
Store Connect, refer to App Store Connect Help.
You can't use Square to sell digital goods in your app. Apple will only allow you to use StoreKit.
You can implement this directly, which may be annoying for flutter especially for subscriptions. You can also use an SDK like RevenueCat's Flutter SDK. (Full disclosure, I'm the CEO of RevenueCat).

Will I be able to have 3rd party payment system in my iOS app?

I'm developing an iOS app where users can ask for advice to influential people on their subject. In order to interact with these people you have to pay the price they set. Once you pay you are able to engage with them on a private chat.
There is an app called Healthtap which does almost the same but with doctors.
I wanted to know if we might be able to use paypal and stripe payment systems instead of apple's.
For more info, I'm building it with HTML5 and making it native with Phonegap
Thanks!
You "have" to use apple's system when paying will add more content to the app, which seems to me, is what you are trying to do.
From Apple's In-App Purchase Programs:
You should read this if you are interested in offering additional
paid functionality to users from within your application.
You can use other payment methods when you are not adding new functionality to the app but rather buy something else in the real world. This is the reason why apps such as Amazon's kindle stopped selling ebooks through their apps, since they did not want to share their profits with apple.
No, Apple does not allow any third-party payment methods to be presented in the app itself; it's IAP or nothing.
What you CAN do is have the third-party payment system as part of your web site and have your users make payments through the web site. You will then need some authentication system in the app that uses to validate the user's payment.

How to make payment with different amount via In app purchase in iphone sdk?

Please tell me How to make payment with different amount via In app purchase in iphone sdk?? as i am creating an application in which subscription charges deduced from a website and in the same way i want to make payment using my application and subscription amount change all the time.. as apple don't approve paypal for the same purpose. How to handle this problem??
can we use web services for deduction of charges and get response of success or failure from web services?
For in-app purchases of app content, you're only allowed to use Apple's In-App Purchase system. You're not allowed to use paypal or anything else from in the app.
The only way to set the price of an in-app purchase item is in iTunes Connect. StoreKit (the API you use for in-app purchases) gets product prices from iTunes Connect, and there is no API for overriding the prices from within the app.
There's no public API (as far as I know) for changing the price in iTunes Connect, either. Perhaps you can script the normal web browsing interface, or find code someone else has written that scripts it. But the only way that Apple provides for changing the price of an in-app purchase is to log in to the iTunes Connect web site in a web browser.
