I am trying to fire an ExactTarget triggered email using the Salesforce developer console. I am now getting the error "Problem initating message send during deserialization of JSON payload"

Http http2 = new Http();  
HttpRequest req2 = new HttpRequest();
req2.setMethod('POST');
  req2.setEndpoint('https://www.exacttargetapis.com/messaging/v1/messageDefinitionSends/b315a0e9-3618-e411-b6d6-b4b52f5cc7b0/send?access_token='+accessToken);
  req.setHeader('Content-Type', 'application/json');


 String SendId='"Address to send to"'   ;
 String MyEmail='"My Email"';
 String MyName='"My Name"';

  req2.setBody('To=' + SendId +'&From=' +MyEmail +'&From_Name=' +MyName);

 HttpResponse res2 = http.send(req2);
System.debug('Fulfillment service on Triggered Send '+ res2.getBody());

I believe my issue is setting up the JSON string to pass into the body for ET. Does anybody know how to fix this?

The Body of the request in the question doesn't appear to be valid JSON.

From the POST /messageDefinitionSends it should look more like:

{
    "From": {
        "Address": "[email protected]",
        "Name": "Code@"
    },
    "To": {
        "Address": "[email protected]",
        "SubscriberKey": "[email protected]",
        "ContactAttributes": {
            "SubscriberAttributes": {
                "Region": "West",
                "City": "Indianapolis",
                "State": "IN"
            }
        }
    }
}

The JSONGenerator should help in creating this for you. As a start:

JSONGenerator gen = JSON.createGenerator(true);

gen.writeStartObject();

gen.writeFieldName('From');

gen.writeStartObject();
gen.writeStringField('Address', MyEmail);
gen.writeStringField('Name', MyName);
gen.writeEndObject();

gen.writeFieldName('To');
gen.writeStartObject();
gen.writeStringField('Address', SendId);
// You might need to set the SubscriberKey etc... here?
gen.writeEndObject();

String pretty = gen.getAsString();
System.debug(pretty);

req2.setBody(pretty);

  • Thank you so much, I added your snippet of code, as well as the subscriberkey section. However I am now getting the error Fulfillment service on Triggered Send {"requestId":"461fd7e9-ac39-4cfa-b67f-6414d71eeb4f","responses":[{"recipientSendId":"","hasErrors":true,"messages":["InvalidOrMissingTo"]}]} What is that coming from?

  • @BalazsHoranyi Is the value in the SendId a valid email address?

  • @ DanielBallinger, Yes it is a valid email address.

  • @BalazsHoranyi I'm not sure how to fix the new error. Maybe try sending a hardcoded JSON string through first and then seeing if you can automate it after that. Was the messageDefinitionSends documentation I linked to the correct API method?

  • Actually came down to a typo in my code. req.setHeader needed to be req2.setHeader. Thanks for all the help
