Participant Groups | Prolific API

Participant groups are saved groups of participant IDs, so you can re-contact the exact same participants across studies. They are dynamic in nature, so you can add and remove participants from the group on the fly and any studies published with a participant group allowlist or participant group blocklist filter will be updated automatically. Participant groups allow you do the following:

Create a new participant group within the scope of a project.
Add and remove users manually to / from the participant group.
Use one or more participant groups as allowlist or blocklist filters for a new study.
Combined with study completion codes, automatically add or remove participants from a group when they submit a response to your study with the correct code.
Any participants added to or removed from the participant group on the fly will be automatically eligible or ineligible for studies that use a participant group allowlist or blocklist filter.
