Tag or Background data not populating for some responses. | XM Community
Skip to main content

Hi

I'm in a bit difficult situation and wonder if someone could throw some light to the issue.

Context:

I have set up a survey which is live at the moment.

The survey is sent from SFMC and the first question is embedded in the invite in SFMC. I have added individual scale links to the scale in invite.

Some background data's are added in the url through query string.

It is encrypted using Base 64 format.

Problem:

When the survey started to collect data, around 50% of completes are missing the background data.

  • I checked to see any issues in the lead file format is causing the issue, but all looks good.
  • I collected the meta data and couldn’t find any pattern in browser or OS which is causing the issue.

 

Have you faced any issue similar to this?

I really appreciate any thoughts on what's causing the issue?

 

Thank you,

Praveen

Hi @praveengeorgeix ,

 

Can you check if these fields are being collected in the Data and Analysis section of Qualtrics after the survey is answered?
Try to add an embedded data Q_URL int he survey flow and then check what is the URL through which the respondent answered the survey. See if this URL has all the query string param that you passed from SF Mcloud.

Lastly, I know there’s a limitation on the size of URL, the characters in it, I think 1024 is the max characters, but please check this once.

In case you facing this issue because of the character limitation, you can try to pass ID’s in the URL and then decode these ID’s in Qualtrics side where 1 could refer to Male and 2 could refer to Female and so on.

 

Let me know if any of the above helps.

Thanks @Sowrabh1993 

The character length looks good. its around 450 characters.

Thanks for the tip in url.

 

I have added it. Now waiting to get some responses. that could throw some light I hope.

Thank you,

Praveen

Great… Once you collect some responses do check if the URL is correctly built at source… that way you can reach to the bottom of the issue.

Also, please make sure that the embedded data fields are declared exactly as passed in the URL(Case sensitive) and there are no special chars in ED names.

 

Let me know how it goes…

I fount the data in URL. There was missing “=” sign at the end of encrypted data which was causing the issue. This is now solved. Thank you so much
