Next to identifying your users, you can also use URL parameters to pre-select survey responses or provide contextual data.
This feature allows you for example to create one link for each possible response value and include them in your emails.
One example for this technique is to ask your customers if they are satisfied with your service and then offer one dedicated link for each possible answer (Very satisfied, Somehow satisfied, …).
Below you can see an example link that identifies your user by their email address (see above) and sets the response of a NPS survey to the value 9 / 10 by providing a ‘response_nps’ parameter.
As you can see, the value is set by a parameter that starts with “response_” followed by the identifier of the question.
To find the identifier of a any question in your survey, click on “Show Advanced Options” in the survey editor and locate the field “Internal Identifier”.
This is method works even if none of your questions has the provided identifier. This way, you can add “hidden field” response data by adding a “response_<something>” parameter.
