Config.json inArguments Data Binding with Marketing Cloud

Question

I'm struggling to configure my app with Marketing Cloud, after define my JB (setting Entry Event and Data Extension properly) my inArguments isn't binding with the event (I'm using Jmeter to execute the tests) I really don't know what I'm doing wrong.

"arguments": {
    "execute": {
        "inArguments":[
            { "firstName":"{{Interaction.5f854a37-40cd-4dc6-81cf-f55c4bb89d98.CPF}}"}
        ],
        "outArguments": [
            { "teste":"number" }
        ],

Also I tried other ways, like replacing Interaction to Event and using different Event API keys, inside my journey builder when I click inside the event I'have this one : APIEvent-649122ef-96c4-c22e-815f-eb9b508b7fec

Also inside my app I have this following code to get this inArgument

var aArgs = req.body.inArguments;
console.log('[aArgs]:'+aArgs);
console.log('[aArgs]:'+req.body);
var oArgs = {};
for (var i=0; i<aArgs.length; i++) {
  for (var key in aArgs[i]) {
    oArgs[key] = aArgs[i][key];
    console.log('[key]:'+key+';oArgs[key]:'+oArgs[key]);
  }
}

My log is showing :

2017-04-20T02:22:13.889030+00:00 app[web.1]: [aArgs]:[object Object]
2017-04-20T02:22:13.888985+00:00 app[web.1]: [aArgs]:[object Object],[object Object],[object Object],[object Object],[object Object]

2017-04-20T02:22:13.889237+00:00 app[web.1]: [fname]:

Also inside my Data Extension model I have the CPF field

Can you guys please help me ?

Thanks a lot !

Answer 1

You are using data binding in the Interaction context, specifically, the binding you are getting the CPF value of outArgument from a prior Custom Activity with the key 5f854a37-40cd-4dc6-81cf-f55c4bb89d98 which I'm pretty sure is not what you want. (side note: you can only retrieve OutArguments from prior Custom Activities, not standard Activities).

If you have a field named CPF in your Event Source Data Extension and you want to use this as an inArgument, then your data binding should look like this:

{{Event.eventDefinitionKey.CPF}}

Where eventDefinitionKey is the Event Definition Key value for the Event.
