SSJS HTTP.Post ValidEmail with requested Access Token

Question

I am trying to make an API request in SFMC to validate email addresses, which requires first to get the Access Token.

I was able to request the access token, but then the next HTTP.Post request I do doesn't work. I have this far:

Platform.Load("core","1.1.5");


var dataRows = Platform.Function.LookupRows('NameofEmailsDE','ColumnName2Check','ValueName');
 if(dataRows && dataRows.length > 0) {
      for(var i=0; i<dataRows.length; i++) {

        var EmailAddress = dataRows[i]["ColumnNameToRetrieve"];

try {
        var authEndpoint = "https://uniqueclienturlapi.auth.marketingcloudapis.com";
        var client_id = "XXXXXXXXXXX";
        var client_secret = "XXXXXXXXXXX";
        var account_id = "XXXXXXXXX";
        var grant_type = "client_credentials";

        // auth        
        var url = authEndpoint + '/v2/token';
        var contentType = 'application/json';
        var payload = '{"grant_type":"' + grant_type + '",';
        payload += '"client_id":"' + client_id + '",';
        payload += '"client_secret":"' + client_secret + '"}';

        // create token
        var accessTokenResult = HTTP.Post(url, contentType, payload);
        var statusCode = result["StatusCode"];
        var response = accessTokenResult["Response"][0];
        var access_token = Platform.Function.ParseJSON(response).access_token; 



 /* Until here, the request works, and I get the access_token. The issue comes in this next request when I have to add to the HTTP.Post the headerNames + headerValues */



        var restEndpoint = "https://uniqueclienturlapi.rest.marketingcloudapis.com";
        restEndpoint += "/address/v1/validateEmail";  
        var headerNames = ["Authorization"];
        var headerValues = ["Bearer " + access_token]; 

        // payload
          var restpayload = '{';
          restpayload += ' "email": "' + EmailAddress + '",'; 
          restpayload += ' "validators": [ "SyntaxValidator", "MXValidator", "ListDetectiveValidator" ]';
          restpayload += '}';                            

        try {
            var restresult = HTTP.Post(restEndpoint, contentType, restpayload, headerNames, headerValues);
            var reststatusCode = result["StatusCode"];
            var response = restresult["Response"][0];
            var emailresponse = Platform.Function.ParseJSON(response).email;
            var validresponse = Platform.Function.ParseJSON(response).valid;
            var failedValidationresponse = Platform.Function.ParseJSON(response).failedValidation;
            }
        catch (err)  {
            // error
            //Write("error");
            }             
    }           

  catch (err)  {
    // error
    //Write("error");
    } 
  }     
}

I would appreciate any help! Thanks a lot

Answer 1

for those who are waiting/looking for an answer on this topic this is how I implemented after many tries.

So this can actually work for any SSJS API call which requires the accessToken to proceed.

STEPS:

1) I created a first DataExt called 'ClientId_and_Secret_RequestToken' with 3 columns: TokenVersion, clientId, clientSecret and stored my credentials (this avoids anyone to inspect the page and take you clientId/clientSecret)

2) Second DataExt which contains the Email Addresses to validate (Columns: EmailAddress & toCheck)

3) Check the comments in the code

<script runat="server">
   Platform.Load("Core", "1.1.1");

   var TokenVersion = 2;
   // Initiate the first DataExt
   var credentialsDE = DataExtension.Init('ClientId_and_Secret_RequestToken');

   // Lookup for the right credentials
   var lookup = credentialsDE.Rows.Lookup(["TokenVersion"],[TokenVersion]);

        if (lookup.length > 0 ) {
            for (var i = 0; lookup.length > i; i++){
                //Set each variable
                var clientId = lookup[i]["clientId"];
                var clientSecret = lookup[i]["clientSecret"];
            }
        }

    var EmailValidationOutput = DataExtension.Init("EmailAddress2Check");

    //Lookup EmailAddresses in the second DataExt and loop what's next
    var dataRows = Platform.Function.LookupRows('EmailAddress2Check','toCheck','True');
        for(var i=0; i<dataRows.length; i++) {

            var EmailAddress = dataRows[i]["EmailAddress"];
            Variable.SetValue("EmailAddress",EmailAddress);
                try {
                  //API to requestToken
                    var url = 'https://{{UniqueClientURLapi}}.auth.marketingcloudapis.com/v2/token';
                    var contentType = 'application/json';
                    var payload = '{"grant_type": "client_credentials", "client_id": "' + clientId + '","client_secret": "' + clientSecret + '"}';
                    var accessTokenResult = HTTP.Post(url, contentType, payload); // HTTP POST call with parameters

                    var obj = Platform.Function.ParseJSON(accessTokenResult.Response + ''); // Parsing the JSON Response to get the token
                    var statusCode = accessTokenResult["StatusCode"];
                    var response = accessTokenResult["Response"][0];
             var accessToken = Platform.Function.ParseJSON(response).access_token;
                    var BearerT = 'Bearer ' + accessToken;

                    if (statusCode === 200) {
                        // Another API call here or something else     
                        var jbHeaderNames = ["Authorization"];
                        var jbHeaderValues = [BearerT];
                        var jbContentType = 'application/json';

               //Here can be changed for any API request

                        var restEndpoint = "https://{{UniqueClientURLapi}}.rest.marketingcloudapis.com/address/v1/validateEmail";
                        var jbPayload = '{"email": "' + EmailAddress + '" , "validators": [ "SyntaxValidator", "MXValidator", "ListDetectiveValidator" ]}';    
                        var validationResult = HTTP.Post(restEndpoint, jbContentType, jbPayload, jbHeaderNames, jbHeaderValues);
                        var validation = validationResult["Response"][0];
                        var emailResponse = Platform.Function.ParseJSON(validation).email;
                        var valid = Platform.Function.ParseJSON(validation).valid;
                        var failedValidation = Platform.Function.ParseJSON(validation).failedValidation;


                    // Debug info below
                    Write('<br>'+emailResponse + '<br>');
                    Write(valid + '<br>' + '<br>');
                    Write(failedValidation + '<br>');

                    } else {
                        // block of code to be executed if the condition1 is false
                    }
                } catch (ex) {
                    Write("error message: " + ex);
                }
        }    
</script> ```
