Hello Kristen,

I apologize for the delay. We typically try and get to our forum posts within a couple of weeks, but since you are a premium user you can opt to use your support portal. Questions posted there are answered much faster. Let me know if you need assistance getting to that support portal, or if you just wanted to contribute to our forums!

Yes, this is possible via the RLabKey API. You can either create a new list and set the "URL" property at the time of creation or you can modify an existing list. Since your scenario fits the latter I will provide an example of how this can be accomplished. R code example attached.

Steps.

1. Retrieve the list you want to modify using "labkey.domain.get"
2. Modify the returned domain to include the URL on the desired field. Use the urlEncoding doc to help you determine the link. Linked below.
3. Save the modified domain using "labkey.domain.save"

Thanks,
Chet
