Keep getting response code 500 in Cardpointe API call-CodePudding

I keep getting a 500 response code in an API call to the Cardpointe gateway (cardconnect) any insight will help. (I was able to verify the test credentials by just posting to the URL without the auth endpoint)

Here is my code in a Google apps script:

function myFunction() {

  var messagesUrl = "https://fts-uat.cardconnect.com/cardconnect/rest/auth";
  var cred = "testing:testing123";
    
  var payload = JSON.stringify({
  "merchid" : "496160873888",
  "account": "4788250000121443",
  "expiry": "1218",
  "cvv2": "123",
  "amount": "100",
  "phone": "15558889999",
  "capture": "y"
  });

  
  var options = {
    "method" : "put",
   "payload" : payload
  };
  
  options.headers = {    
    "Authorization" : "Basic "   Utilities.base64Encode(cred)
    },{
    "Content-Type" : "application/json"
    }
  var res = UrlFetchApp.fetch(messagesUrl, options);
  
  Logger.log(res);
  
}

CodePudding user response：

options.headers = {    
    "Authorization" : "Basic "   Utilities.base64Encode(cred)
    },{
    "Content-Type" : "application/json"
    }

Here content type is not set to options.headers.

/*<ignore>*/console.config({maximize:true,timeStamps:false,autoScroll:false});/*</ignore>*/ 
const options ={};
options.headers = {    
"Authorization" : "Basic "   "b64"
},{
"Content-Type" : "application/json"
}
console.log(options)

headers should be a single object with multiple keys:

options.headers = {    
    "Authorization" : "Basic "   Utilities.base64Encode(cred),
    "Content-Type" : "application/json"
    }

/*<ignore>*/console.config({maximize:true,timeStamps:false,autoScroll:false});/*</ignore>*/ 
const options={}
options.headers = {    
"Authorization" : "Basic "   "b64",
"Content-Type" : "application/json"
}
console.log(options)

<!-- https://meta.stackoverflow.com/a/375985/ -->    <script src="https://gh-canon.github.io/stack-snippet-console/console.min.js"></script>

/*<ignore>*/console.config({maximize:true,timeStamps:false,autoScroll:false});/*</ignore>*/ 
let a;
a = 1,3;
console.log(a);// no 3
