DMP Trait via API

[razai22062698]

Hey Guys,

It's Raza from Bank of Montreal Canada, I am a part of Personalization team here. We are working on something and we need some help. Do anybody have idea about creating a DMP Trait using API. What are prerequisites and other things ?

As of current scenario I have created a tool to generate DMP ruleset and then we copy that ruleset and manually apply that to Adobe Audience Manager(AAM). And In a future iteration of this tool, i'd like to use the AAM APIs within tool to automatically create that rule in AAM once someone clicks the "generate button".  But first we need to investigate how to use the API

Hi Raza,

This query seems to be more related to Adobe Audience Manager . Hence moving the query to Audience Manager Community.

Hi Raza,

Here's the link to documentation for Audience Manager's REST APIs​.

Trait API Methods​ have been rewritten with Swagger.

Hope this helps.

Hey, Thank you so much Dev I already checked these links and they are really helpful. I am working on a javascript to create DMP trait in AAM and below is so far what I have created, can you please have look and suggest.

var Data = '[{ "pid": 0, "name": "TestData", "description": "TestData", "integrationCode": "TestData", "comments": "TestData", "traitType": "TestData", "status": "TestData", "dataSourceId": 0, "folderId": 0, "traitRule": "TestData", "type": 0, "categoryId": 0, "crUID": 0, "upUID": 0, "createTime": 0, "updateTime": 0 }]';

    var xhttp = new XMLHttpRequest();

    xhttp.open("POST", "https://api.demdex.com/v1/traits/", false);

    xhttp.setRequestHeader("Content-type", "application/json");

    xhttp.send(Data);

    var response = JSON.parse(xhttp.responseText);

	console.log(xhttp.status);
	console.log(xhttp.statusText);
	console.log(response);

Thank you Parit hoping great answers in new community as well

Hey Raza,

Your code seems to be fine while using the AAM traits API. Were you able to solve your use case?

Best,

Hi Gaurang,

I am facing authorization issue while using this code, do you have any idea how to setup authorization as given in this link ? I have Client ID and Client secret

[DSRehan]

Hi Raza,

You will need to generate an access_token to make API requests. You will need to make an API request to request the access_token.

I am pasting the screenshots below from my demo setup to show how the call should look like:

Header Configuration:

Body Configuration:

The most important part that people tend to miss out on is encoding the Client ID & Secret to Base64 string.

Hey,

I have done just like this, still receiving the unauthorized error . Please check the code below (Note : I am running this code from a local HTML file, I have not published anything yet on the http):

$.get( {

    url: 'https://api-beta.demdex.com/oauth/token',

    type: 'POST',

    dataType : "jsonp",

    data: { content: 'grant_type=password&username=<My AudienceManager user name>&password=<My AudienceManager password>' },

    beforeSend : function( xhr ) {

        xhr.setRequestHeader( "Authorization", "Basic <base-64 clientID:clientSecret>" );

        xhr.setRequestHeader( "Content-Type", "application/x-www-form-urlencoded" );

    },

    success: function( response ) {

  //response

    }

} );

Hello Razai,

Can you please give a sample request with dummy data (please use dummy values for user or account specific information)?

Regards,

Unni

[razai22062698]

Hi Unni,

Please find sample request below :

$.get( {

    url: 'https://api-beta.demdex.com/oauth/token',

    type: 'POST',

  dataType : "jsonp",

    data: { content: 'grant_type=password&username=ABCDEFHG&password=XOXOX1234' },

    beforeSend : function( xhr ) {

        xhr.setRequestHeader( "Authorization", "Basic Ym1vZW5jam1vZWFsLW1bXQ6NjRn3djlrN211nbXQ6NjRcWc5YmhwZmIyYjlmVwbzRtcmJpbaTF0" );

  xhr.setRequestHeader( "Content-Type", "application/x-www-form-urlencoded" );

    },

    success: function( response ) {

  var responseData = JSON.parse(response);

  console.log(responseData);

    }

} );

Hi Raza,

Adding to what Devinder shared with you earlier... In case you are using Postman tool for making these requests, here is another thing to keep in mind: we get the following error message when we choose the “Authorization Type” as something other than “No Auth” (assuming that we enter the correct credentials – UN & password for Audience Manager).

So as step 1 in Postman, under "Authorization" tab, you should select "No Auth" as Type. See screenshot below.

And then under the tab "Header", for the key "Authorization" the value should be “Basic <base-64 clientID:clientSecret>”

If we select any other Type under tab "Authorization", I see that we get the following response. Is this the error you are getting too?

"{"error":"invalid_grant","error_description":"Bad credentials"}".

[unnikrishnanv18]

The auth token request needs to be made against https://api.demdex.com/oauth/token  if the user credentials are for the production account.

[razai22062698]

Hey Aman,

I am not using any tool, I am just doing it via Javascript. I feel there is some cross domain issue.

[razai22062698]

Hi Unni,

I have tried both beta and production site, still facing the same issue. I think this might be a cross domain issue as I am runnin code from a local file

[razai22062698]

I am getting this : XMLHttpRequest cannot load https://api.demdex.com/oauth/token. Response to preflight request doesn't pass access control check: No 'Access-Control-Allow-Origin' header is present on the requested resource. Origin 'null' is therefore not allowed access. The response had HTTP status code 401.

[razai22062698]

I feel the problem is with requesting token using Javascript, because when I requested token using JSON client like Postman or ARC(Advance REST Client) It work successfully and I got the JSON response with Access Token. Do you have idea to get Token using Javascript or AJAX ?

[unnikrishnanv18]

Hey Razai,

I used a PHP script and was able to get an auth token by setting the mentioned headers. You'll need to check with your dev team to troubleshoot the custom jQuery script by comparing both the requests to identify which parameter or header is missing or wrongly set.

Cheers,

Unni

Can you please share the code piece ?

[unnikrishnanv18 · Accepted solution]

$base64_code = base64_encode($client_id.":".$client_secret); 
$ch = curl_init(); 
$request_headers = array();
$request_headers[] = 'Content-Type: application/x-www-form-urlencoded';
$request_headers[] = 'Accept: application/json';
$request_headers[] = 'Authorization: Basic '.$base64_code;
$data_to_post = "grant_type=password&username=$username&password=$password";
curl_setopt($ch, CURLOPT_URL, "https://api.demdex.com/oauth/token");
curl_setopt($ch, CURLOPT_RETURNTRANSFER,true);
curl_setopt($ch, CURLOPT_HTTPHEADER, $request_headers);
curl_setopt($ch, CURLOPT_POST, 1);
curl_setopt($ch, CURLOPT_POSTFIELDS, $data_to_post);
curl_setopt($ch, CURLOPT_SSL_VERIFYPEER, false);
$result = curl_exec($ch);
$res = json_decode($result,true);
$access_token = $res['access_token'];
