The Prolific API uses API token to authenticate requests. You can create an API token directly from your settings.
Your API token does not have an expiry date and carries full permission, so be sure to keep them secure.
If your token is leaked, delete it and create a new one directly in the app.
In your requests add Authorization header with the value Token <your token>.
Control the balance between speed of your studies and the naivety of the participants.
If not defined, by default Prolific calculates the best rate for most studies
taking into account the filters and the total_available_places needed for this study.
Use 0 if your priority is speed. When this property is set to 0 all eligible participants will have access to your study at the same time, without any prioritization.
You can also set this at a project and study level.
