Collect external ID:s to your Netigate survey

For certain surveys, you might want or need to collect information about your respondents, even though the survey is answered from a generic link with no opportunity to use a respondent list. This can be collected via an individual ID assigned to each respondent that you can collect when answers are collected to the survey result.

When do I need to collect external ID:s?

One of the main cases for wanting to collect external ID:s is when conducting a panel survey, that is, sending the survey to unknown respondents in order to collect a result from a specific target group regarding, for example, market research. For most panel providers this is mandatory in order for them to be able to track what respondents have answered the survey, and so for instance be able to compensate them appropriately.

Another case for wanting to collect ID:s could be from a website evaluation where the respondents have entered the survey through a static link on your website. In these cases, this ID can be a visitor ID for example.

What do I have to do?

The first thing that you will need to do is make an addition to the survey link in order for the system to correctly signal that there is an ID connected to the link.

Second thing you will need to do is create a mechanism inside your questionnaire to pick up the unique ID:s when the respondents are entering the survey.

How to include ID:s with the survey link

The addition that you will need to add to the survey link is pretty simple. This is the short tag that you need to add at the end of the link: “&EID=[ID]” or “&CPXID=[ID]

You will need to create a survey link in the distribution of your survey and copy the link. At the end of the link you will need to add the tag for including an external ID: “&EID=[ID]” or “&CPXID=[ID]

The most important part is “&EID=” and “&CPXID=” as these two are the abbreviations used by the system to identify ID:s. The “[ID]” part at the end is something that you will need to replace with the tag or placeholder that you need to use in order to collect ID:s.


This example is connected to a demo NPS survey. You may replace the [ID] at the end of the tag with whatever you wish.

When conducting a “real” survey the [ID] needs to be replaced with the placeholder used by the panel provider, or visitor ID-tag from your website.

Collecting ID:s in the survey result

In the survey you will need to create a Textbox-question. This textbox will be used to collect the external ID:s that are attached to the survey links.

Once you have created the text box you will need to look at the settings of the text box and select the option called “External parameter“. The external parameter will make the textbox invisible to the respondents and will work in the background, collecting ID:s for each of them.

You can insert a header/title to the text box in order to make it easier to identify it when going through the responses.
