React native 如何在React Native中集成Paytm集成

我尝试了react native paytm软件包来集成paytm，它显示了带有404 Not Found错误代码的白色屏幕。这是我的密码-

const details = {
      mode: 'Stage', // 
      mid: "AstraD64640279792570",
      industryType: "Retail",
      website: "APPSTAGING",
      channel: "WAP",
      amount: 1, // String
      orderId:  "ORD3AXYBULQYUQFBBW", // String
      email: "astradairy@gmail.com", // String
      phone: "7777777777", // String
      custId: "2894",// String
      checksumhash:"DHYa9kmlmLT4tAGQC5e+95xLk+iqm8pIT7HapH1gCl+rVLFQJNb9Xfi+0eKgQ2KVuGYg5SR3Ss+BClnv9uAVmibWCl7KBiwVHK7E1ElSapA=", //From your server using PayTM Checksum Utility 
      callback: "https://securegw.paytm.in/theia/paytmCallback?ORDER_ID=ORD3AXYBULQYUQFBBW",
 };
 paytm.startPayment(details);
