If you've collected extra data about your survey respondents in advance, iSalient allows you to pass these values into a survey to be included in your data set. This is done by adding the data onto the end of the survey link you send your invitees.
Let's say you've installed iSalient on your web site at example.com. A typical survey link would look like:
You can add your data onto the end of this link using an ampersand (&). So, if you wanted to include the zip code of your invitee, you would add an ampersand, indicating that a value has been added, followed by the value itself: zip_code=60601. You final survey link for that invitee would look like:
Only basic alphanumeric characters should be included in the name of your value--no spaces should be used. In this example, we've used an underscore (_) instead of a space.
You can add on as many values as you'd like in this manner, simply by placing an ampersand before each value. For example:
When the survey is opened through this link, iSalient will automatically store the values "zip_code" and "name" along with all other survey data, such that you can view the data along with the invitee's survey responses and export it for manipulation in statistical analysis software.
