Public Survey Link Participant List Survey Invitation Log

Using a public survey link is the simplest and fastest way to collect responses for your survey. You may obtain the survey link below to email it to your participants. Responses will be collected anonymously (unless the survey contains questions asking for identifying data from the participant). NOTE: Since this method uses a single survey link for all participants, it allows for the possibility of participants taking the survey multiple times, which may be necessary in some cases.

To obtain the survey link, copy the URL below and paste it into the body of an email message in your own email client. Your email recipient(s) can then click the link to begin taking your survey.

Public Survey URL:
Link Actions
     
Link Customizations
You may create a short and easy to remember custom URL that redirects to your public survey. Enter the your desired custom URL that you wish to redirect to your public survey. When submitted, it will check if the URL has already been taken. If not, it will save the custom URL here in your project so that you may continue to use it.
https://redcap.link/
NOTICE: The ending of custom URLs may only contain letters, numbers, dots/periods, dashes, and underscores.
NOTICE TO ADMINISTRATOR: The Google reCAPTCHA feature for protecting public surveys is currently DISABLED at the system-level for all projects, but if you wish, you may enable the option on the Modules/Services Configuration page in the Control Center. This option will allow users to add protection to their public survey using Google's reCAPTCHA functionality, which can prevent bots from entering trash data into a public survey.
Response cannot be viewed:
When clicking the 'Responded' icon, you may only view responses that have a Participant Identifier defined. Thus you will not be able to view this participant's response by clicking this icon. This is done in order to preserve this response as anonymous.
Among the participants selected, 0 participants have survey invitations that are already scheduled to be sent. These participants will have their survey invitations rescheduled for the new time you specified. If you do not wish to reschedule them but instead wish to keep the current scheduled time, then click the Cancel button below and deselect them in the list.
