I am unable to post my json to my api lambda function.I am getting {"message":"Missing Authentication Token"}

enter image description hereenter image description hereActually everything runs fine when I import the json to my POSTMAN application and send the request .But problem arises when I try to POST using an ajax call or directly hit the api

I had tried to remove api key and made every authorization none

This is my API - https://ym4j4pt5mf.execute-api.us-east-1.amazonaws.com/Beta And I am trying to post this as raw body:-

{
  "DestinationBot": "iSearchBot",
  "SenderID": "12345",
  "botAlias": "iSearchBotBeta",
  "message": {
    "text": "hi"
  }
}

This is the response that I get when I hit the api by importing it from api gateway via POSTMAN

        ]
    }

Solution

  • Well this will solve your problem i guess the problem was with json stringify it works easily

    <!DOCTYPE html>
<html>
<head>
<script src="http://ajax.googleapis.com/ajax/libs/jquery/3.3.1/jquery.min.js"></script>
<script>
$(document).ready(function(){

var value={ 
  'DestinationBot': "iSearchBot",
  'SenderID': "12345",
  'botAlias': "iSearchBotBeta",
  'message': {
    'text': "hi"
  }
};
value = JSON.stringify(value);
$.ajax({
  url:'https://ym4j4pt5mf.execute-api.us-east-1.amazonaws.com/Beta/',
  headers:{  
    'Content-Type': "application/json",   
  },
  crossDomain: true,
  method:'POST',
  dataType:'json',
  data:value,
  success:function(msg){
    console.log(msg)
  }
});
});

</script>
</head>
<body>

<input type="text"></input>

</body>
</html>
