You can create a custom survey URL that contains a segment. Turn on the segmentation for a survey by opening the survey, click on Settings, from Additional features, select Enable segmentation and click Save.
Generating a custom link
Now you can create your custom URLs by adding p[segment_number]=[segment_value] as the query parameter. You can get the base URL from opening the survey and clicking Collect and copying the URL address.
What can a segment contain?
You should preferably use IDs from your system. Please use only URL safe characters in the parameters: numbers (0-9), characters (a-z) and special characters "-" and "_". You should not use human readable segments, eg. name of product purchased.
You will see the given segments under each answer and you can also export all the answers with the segments to a .csv or Excel for further processing. Filtering in the app by segments is currently not possible.
