title: How to solve {"message":"Missing Authentication Token"} error?
body: <p>So I deployed an API (aws api gateway) and when I got the invoke url and filled in the parameters, I get the following error:</p>
  
  <pre><code>{"message":"Missing Authentication Token"}
  </code></pre>
  
  <p>I looked at cloud watch and the lambda function was called, but the parameters I fed it were all empty. And I have no idea whats going on.</p>
  
  <p>Here is my invoke url:</p>
  
  <pre><code>https://mupb23gx76.execute-api.us-west-2.amazonaws.com/userAPI/adduser
  </code></pre>
  
  <p>Here is the invoke url with all the parameters:</p>
  
  <pre><code>https://mupb23gx76.execute-api.us-west-2.amazonaws.com/userAPI/adduser?username=karan&amp;firstName=karan&amp;lastName=chitnis&amp;email=gmail&amp;profileImageURL=whatever&amp;phoneNumber=555&amp;birthdate=0109
  </code></pre>
  
  <p>Here is a screen shot of my api structure:</p>
  
  <p><a href="https://i.stack.imgur.com/Dm7Du.png" rel="nofollow noreferrer"><img src="https://i.stack.imgur.com/Dm7Du.png" alt="enter image description here"></a>
  And here is the input model i made for the method request.</p>
  
  <pre><code>{
      "$schema":"http://json-schema.org/draft-04/schema#",
      "type":"object",
      "properties":{
          "email":{"type":"string"},
          "birthdate":{"type":"string"},
          "firstName":{"type":"string"},
          "lastName":{"type":"string"},
          "userName":{"type":"string"},
          "phoneNumber":{"type":"string"},
          "profileImageURL":{"type":"string"}
      },
      "title":"InputaddUser"
  }
  </code></pre>
  
  <p>I DID NOT PUT QUERY STRING PARAMETERS in my method request, I just put added this model. Because I plan on deploying this to android. But I wanted to make sure it worked on invoke url first. </p>
  
  <p><strong>UPDATE</strong></p>
  
  <p>Here is my cloudwatch when i put the url into to Postman. <a href="https://i.stack.imgur.com/NWbIG.png" rel="nofollow noreferrer"><img src="https://i.stack.imgur.com/NWbIG.png" alt="enter image description here"></a></p>
  
  <p>And here is my inputbody:</p>
  
  <pre><code>{
    "email": "qgseg@gmail.com",
    "birthdate": "1/1/1990",
    "firstName": "Qazar",
    "lastName": "Fbaooqui",
    "username": "Caster",
    "phoneNumber": "some #",
    "profileImageURL":"something"
  }
  </code></pre>
