Merging several studies under one participation link
If you have several studies (i.e. different versions of the same test) and you want a similar number of participants to complete each of them, you can merge all of the participation links into one link - it makes it way easier to integrate it with your panel/survey tool.
1. The merging link looks like this:
In this example we are merging three studies, but, if you want, you can add more studies by adding "&study_ids=xxxxxx" for any additional test.
2. Instead of the strings of characters ("aaaaaa", "bbbbbb" and "cccccc", etc.), you need to put a study Id's, that you want to merge. You'll find it on your study dashboard:
Let's assume the study Id's are:
Study 1: 2212a69d-713e-4843-af5b-20430004a01a
Study 2: d510361a-bed2-4f38-9155-556a65243b20
Study 3: de4b505c-2972-47ac-b187-f3ab814e6354
the link would look like this:
Each participant that opens that link sees only one of those studies (picked randomly).
4. To this link you can add variables at the end using the "&", so, i.e.:
In this case, the participant would see one of those studies and for each of them the variable "name" with the value "adam" will be passed in the link.
When one of the studies is finished (i.e., because all participants' slots were already taken), it won't be shown to any of the participants - they'll be only redirected to other studies. If all studies are finished, one of them is displayed at random and leads the participant according to the study rules, so either "quota full URL" or displays information that the study is already closed.
