Share a participation link
Before sharing
- Save your study and set the status to Open or Restricted (open the study and click the status pill at the top of the Study form to choose Open, Restricted, or Closed).
- (Optional) Set a study password in the Description tab. Participants will be prompted to enter it on the welcome screen.
Where to get the links
From your Dashboard studies list, click the Share action on the study row (this opens the study's Sharing tab). The Sharing tab groups both participant link types for your study:
- Open link (open studies only): a public URL that anyone with the link can use, as many times as needed. Use this when you want to distribute the study widely (social media, a recruitment platform, a lab website).
- Invite links (open and restricted studies): single-use URLs that each accept exactly one participant. After that participant completes consent, the link cannot be reused. Use these when you want controlled recruitment, per-channel tracking, or to prevent duplicate submissions.
The Sharing tab also contains a separate researcher sharing section for granting colleagues access to the study; that is covered in the Share a study with collaborators guide and is distinct from the participant links described here.
Each link has a Copy URL button. Clicking it copies the link to your clipboard and shows a brief confirmation message.
Open link
The open link format is:
{origin}/participate?id={studyId}
For example: https://yourapp.example/participate?id=abc123
Only open studies expose this link. Restricted studies require a single-use invite link.
Single-use invite links
Each single-use invite link contains a unique token:
{origin}/participate?id={studyId}&token={tokenId}
Generate and manage single-use invite links from the Share tab of the study. Each click of Generate link creates one new link. After a link is generated, you can attach optional labels to it (e.g., a recruitment channel name) for later analysis, and Revoke any active link you no longer want used.
What participants see
| Study state | Link type | Participant experience |
|---|---|---|
| Open | Open link (no token) | Welcome page > optional password prompt > consent > optional participation form > tasks > conclusion/thanks. |
| Open | Single-use link (valid token) | Same flow as above. After consent, the link is marked consumed and cannot be reused. |
| Open or Restricted | Single-use link (consumed, revoked, unknown, or for another study) | The Consumed link page appears, explaining that the link has already been used and inviting the participant to contact the research team for a new one. |
| Restricted | Single-use link (valid token) | Welcome page onward, same as Open. |
| Closed | Any | A "study closed" message using the text from your Pages tab > Closed study page. |
| Password-protected | Any | A password input appears under the welcome text. Labels and error messages can be customized in UI translations. |
Open the Pages tab of your Study form and select Consumed link page in the sidebar (visible only for Open and Restricted studies). Edit the rich-text message to include your preferred contact information, such as an email link, a lab website, or a phone number, so participants who land on this page know how to reach you if they believe they received the message in error.
Tips
Open the link in a private/incognito window to verify the flow is correct for unauthenticated users.
- If the study includes screen sharing (Recording tab), remind participants they will be prompted by the browser to choose a screen or window after consent.
- If you see a permission error, confirm the study is Open or Restricted (with a valid invite link) and your browser allows camera/microphone access.
