hi I am a CEO of a web servicing-based company and hired an ios developer to build my application with third-party APIs I would like to know how it will apple help me to split payment between the app and APIs or Do I need to go again and again to the APIs dashboard to pay them that's quite impossible for me because if I have heavy traffic so I don't know what to look for anymore can you guys please guide me on this how we will need to manage to pay the APIs?
building an application with third party APIs
Apple has no involvement in your app, other than taking a cut of the upfront cost of a user buying your app (if it's not free).
Apple will have nothing to do with your APIs. If you get a lot of users, and your app uses third-party APIs that charge you for their use, then you will be the one paying for that API usage, not Apple. Price your app accordingly.
Finally, your use of random tags on your post on here is inappropriate. Your question has nothing to do with "Core WLAN" or "App Store Connect" or "Frameworks". Use tags more appropriately so your post is seen by the right people.
