title: How to find merchantId, key and slat from Payumoney
body: <p>I am using react native PayUMoney library</p>
  <pre><code> initPayment(ordId) {
   let ID = this.IDganarate();
  
      let hashkey = HashGenerator({
      key: 'QylhKRVd',
      amount: this.state.total,
     email: &quot;xyz@gmail.com&quot;,
      txnId: &quot;1594976828726&quot;,
      productName: ID,
      firstName: this.state.user_data.name,
      salt: &quot;seVTUgzrgE&quot;,
  });
  
    console.log(hashkey);
  
    const payData = {
      amount: this.state.total,
      txnId: '1594976828726',
      productName: ID,
      firstName: this.state.user_data.name,
      email: 'xyz@gmail.com',
      phone: this.state.pho_num,
      merchantId: '8189479',
      key: 'QylhKRVd',
      successUrl: 'https://www.payumoney.com/mobileapp/payumoney/success.php',
      failedUrl: 'https://www.payumoney.com/mobileapp/payumoney/failure.php',
      isDebug: false,
      hash:hashkey,
  }
  
  Payumoney(payData).then((data) =&gt; {
      this.AddOrder(ID,ID);
  }).catch((e) =&gt; {
      // Payment Failed
      console.log(e)
  })
  }

  <p>When I use testing <code>merchantID</code>, key and slat this is worked perfectly but when I use original <code>merchantID</code>, key and slat it's show me error {&quot;code&quot;: 0, &quot;success&quot;: false}</p>
  <p>I think I am using wrong <code>merchantID</code>, key or slat, if you have any solution then please give me or please answer me that how can I find a right <code>merchantID</code>, key or slat</p>
