It is possible to append a [https://en.wikipedia.org/wiki/Query_string Query-String] to the URL you provide to your participants. Some parameters are handled separately by emoTouch so that you are able to search or filter for the value of these parameters. Specifically these are the eight parameters i1, i2, ..., i8 and the eight parameters s1, s2, ..., s8. The "i" stands for integer, i.e. numbers on which mathematical operations can later be performed, while the "s" stands for string, i.e. character strings.

All other parameters provided in the query string of the URL are also saved but are saved together as a [https://de.wikipedia.org/wiki/JavaScript_Object_Notation JSON] and are not searchable or filterable within emoTouch.

'''Note: if you want to test the parameter transfer before starting the study, use an incognito tab. The following key combinations open a new incognito window, where you can then simply paste the link:'''

== Example ==

Here is a sample URL (realization code: 123abc) with all possible parameter types and sample values:

<big>https://pi.emotouch.de/en/123abc?i1=100&i2=5&s1=hello&s2=world&mykey1=myvalue1&mykey2=myvalue2</big>

This would result in a session with the following structure:

id: 123abc (This is only a sample ID)

i1: 100

i2: 5

s1: hello

s2: world

params: {

mykey1: myvalue1,

mykey2: myvalue2

}

The parameters can be viewed on the details page of a session.
