+ * @name AllInOneSDK
+ * @description
+ * Paytm All-in-One SDK plugin for Cordova/Ionic Applications
+ * Paytm All-in-One SDK provides a swift, secure and seamless payment experience to your users by invoking the Paytm app (if installed on your user’s smartphone) to complete payment for your order.
+ * Paytm All-in-One SDK enables payment acceptance via Paytm wallet, Paytm Payments Bank, saved Debit/Credit cards, Net Banking, BHIM UPI and EMI as available in your customer’s Paytm account. If Paytm app is not installed on a customer's device, the transaction will be processed via web view within the All-in-One SDK.
+ * For more information about Paytm All-in-One SDK, please visit https://developer.paytm.com/docs/all-in-one-sdk/
+ *
+ * @usage
+ * ```typescript
+ * import { AllInOneSDK } from '@ionic-native/all-in-one-sdk/ngx';
+ *
+ *
+ * constructor(private allInOneSDK: AllInOneSDK) { }
+ *
+ * ...
+ *
+ * For below parameters see [documentation](https://developer.paytm.com/docs/all-in-one-sdk/)
+ * let paymentIntent = { mid : merchantID, orderId: orderId, txnToken: transactionToken, amount: amount, isStaging: isStaging, callbackUrl:callBackURL }
+ *
+ * this.allInOneSDK.startTransaction(paymentIntent)
+ *   .then((res: any) => console.log(res))
+ *   .catch((error: any) => console.error(error));
+ *
+ * ```
+ *
+ * For iOS:
+ * After adding the plugin, open the iOS project, you can find the same at <projectName>/platforms/ios.
+ * In case merchant don’t have callback URL, Add an entry into Info.plist LSApplicationQueriesSchemes(Array) Item 0 (String)-> paytm
+ * Add a URL Scheme “paytm”+”MID”
+ *
