How can I tell which link my participants came from?

You can tell which activity link or invitation your participants used to access your survey by adding hidden questions to the survey, with answer values that correspond to the sources you want to track. Then, append the same answer values to the end of the activity link, or the [%ActivityLink%] pipe in an invitation, before you distribute the activity. The appended values are piped into the hidden question and recorded when participants access the link and complete the survey.
