Essentially, we’re using a panel provider who will send respondents our way and they will complete the survey before being redirected back to the panel provider’s website. They have a unique ID (sesskey) which they need to stay in the URL so that when respondents are redirected back to them, they can register who completed the survey based on the unique ID.
Does anyone know a way to do this? If you could provide detailed instructions, that would be great.
You can do this easily with the "panel integration" feature. The ID will not stay in the URL, but you can read the ID into Limesurvey, save it in a text question and at the end of the survey you redirect them via the End URL feature back to the panel provider and add the saved unique ID from the panel provider back to the link.
