Yodlee process MFA with null mfaInfo.fieldInfo - yodlee

Question

According to
https://developer.yodlee.com/Aggregation_API/Aggregation_Services_Guide/API_Flow/Refresh_Account
once I've received response with isMessageAvailable = true and errorCode is empty I should call getMFAResponse (actually I'm using getMFAResponseForSite)
this response should contain not null mfaRefreshInfo.fieldInfo. Unfortunately all cases I was able to test fieldInfo were null.
Could you please help me to understand what I'm doing wrong. SiteAccountId is 10038630.

If you are using getMFAResponseForSite then use this refresh flow
Now response of getMFAResponseForSite depends upon how soon yodlee encounters the MFA after login attempt.
There are 3 types of responses you can get -
{ "isMessageAvailable": false, "timeOutTime": 0, "itemId": 0,
"memSiteAccId": 10000502, "retry": true }
On your 1st call to the MFA API you may get this if there is a delay in bringing the MFA data , hence you need to go back and call this API again (as suggested in the flow to loop).In this case if with messageAvailable if false and timeoutTime > 0 then it means that Yodlee has timed out the request and you can abort the refresh and try re-initiating it.
{
"isMessageAvailable": true,
"fieldInfo": {
"responseFieldType": "text",
"minimumLength": -1,
"maximumLength": 6,
"displayString": "Security Key"
},
"timeOutTime": 97640,
"itemId": 0,
"memSiteAccId": 10000052,
"retry": false
}
This is the case where you get the MFA response. Here you can see that isMessageAvailable is true and you have field info populated. This response can come at 1st call of getMFAResponseForSite or after 1 or 2 loops.
{
"isMessageAvailable": true,
"fieldInfo": {
"questionAndAnswerValues": [],
"numOfMandatoryQuestions": -1
},
"timeOutTime": 98480,
"itemId": 0,
"errorCode": 0,
"memSiteAccId": 10039332,
"retry": false
}
In this case you can see that there is an error code present, if it's 0(zero) that means login was successful without MFA and Yodlee is able to navigate to account summary page. In case error code is non zero then please refer error code page
Now in your case the siteAccountID is failing with error code 429 and hence you should be getting that information in getMFAResponseForSite API.
can you make sure you are following the right refresh flow and making the right API calls as ideally the behavior will not change from what is represented in the flow diagram.
