I have an app that allows users to complete a video call and then bills them a per-minute charge for the length of the call. How can I automatically bill my app user using in-app purchase without prompting for approval? I'm using Stripe on the web to complete an automatic purchase with the user's stored credit card. How do I accomplish the same thing on the web while on Apple device (or within my app) without prompting them for approval? They've already given approval by completing the call. I am aware that I can create an in-app purchase product for the necessary "credits" but this will prompt them to complete the purchase which should instead be automatic. Thanks!

I'm setting appAccountToken for my autorenewing subscriptions and when a purchase completes I get the token back in the transaction. However, when I test "Ask to Purchase" and create a pending transaction, the approved transaction that is returned does not contain the appAccountToken. I need this, so what am I missing? I'm using a listener and an update function.    func listenForTransactions() -> Task<Void, Error> {     return Task.detached {       // iterate through any transactions that don't come from a direct call to 'purchase()'.       for await result in Transaction.updates {         do {           let transaction = try await self.checkVerified(result)           //Deliver products to the user.           await self.updateCustomerProductStatus()           await transaction.finish()         } catch {           print("Transaction failed verification.")         }       }     }   }    func updateCustomerProductStatus() async {     var purchasedSubscriptions: [Product] = []           //iterate through all of the user's purchased products.     for await result in Transaction.currentEntitlements {       do {         //Check whether the transaction is verified.         let transaction = try checkVerified(result)                   //Check the 'productType' of the transaction and get the corresponding product from the store.         switch transaction.productType {           case .consumable:             //do nothing             break           case .nonConsumable:             //do nothing             break           case .nonRenewable:             //do nothing             break           case .autoRenewable:             if let subscription = subscriptions.first(where: { $0.id == transaction.productID}) {               purchasedSubscriptions.append(subscription)                               //Post subscription status back to MYAPPSERVER.               print("transaction: ",transaction)               //API Call to MYAPPSERVER               let params: [String: AnyHashable] = [                 "token":transaction.appAccountToken!.uuidString,                 "item":transaction.productID,                 "transaction":transaction.originalID               ]               guard let apiURL = URL(string:"https://MYAPPSERVER/version-test/api/1.1/wf/ios-sub") else {return}               var request = URLRequest(url:apiURL)               request.httpMethod = "POST"               request.setValue("Application/json", forHTTPHeaderField: "Content-Type")               request.httpBody = try? JSONSerialization.data(withJSONObject: params, options:[.fragmentsAllowed])               let session = URLSession.shared.dataTask(with: request) { data, response, error in                 if let error = error {                   print("Error sending subscription to Dryft: \(error.localizedDescription)")                 }else{                   if let jsonResponse = try? JSONSerialization.jsonObject(with: data!, options: [.fragmentsAllowed]) {                     print("The response: \(jsonResponse)")                                           }                   }                 }               }.resume()             }           default:             break         }       } catch {           print("Unknown transaction type.")       }     }     //Update the store information with the purchased products.     self.purchasedSubscriptions = purchasedSubscriptions              }
