Collect external ID:s to your Netigate survey

For certain surveys, when you 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 respondentlist. This can be collected via an individual ID assigned to the respondent that you can collect when answers are collected to the survey result.

When do I need to collect external ID:s?

The main reason for wanting to collect external ID:s is when conducting a panel survey, 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, in order to be able to compensate them appropriately.

Another reason for wanting to collect ID:s could be from a website evaluation where the respondent have entered the survey through a static link on your website. This ID can in these cases 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 on survey link

The addition that you will need to add to the survey link is pretty simple. This is a 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 textbox you will need to look at the settings of the textbox 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 the respondents.

You can insert a header/title to the textbox in order to make it easier to identfy when going through the responses.
