How to store external respondent IDs in Kobo forms using

Hi everyone,
I’m working with single submission links in Kobo (using the /single/{UID} endpoint) because I need to redirect respondents to an external dashboard after they complete the form.
My link looks like this:


https://ee.kobotoolbox.org/single/AB12CD34?return_url=https://www.example.com/redirect?rid=5678

What I’m trying to do is store the rid (respondent ID or panelist ID) inside the Kobo dataset, so I can later match the submission with data from my external system.
I’ve already tried:

  • pulldata("@query","rid")

  • query("rid")

  • Adding a text field named rid and using ?rid=... in the URL

But it seems that /single/ links ignore URL parameters (other than return_url), and I can’t find a way to access or save the rid value in the form submission.
Is there any way, either through form logic, hidden calculations, or any other method, to store a unique respondent ID when using /single/ links with a redirect URL?
Thanks in advance!

@Erblina, have you gone through these support articles? It should be helpful to pull certain variables to your form that is stored either in the server project or in a CSV file.
