To link answers in your survey tool to participants in Prolific, you'll need to set up your survey to record our participants' unique Prolific IDs.
This enables you to match our participant demographic data with responses. If you do not record participant IDs, you will not know who has submitted which individual survey response. As a result, you won't know which ones deserve approval or rejection.
We recommend recording IDs automatically, which can be done using URL parameters. Alternatively, you can include a question in your study asking participants for their ID.
What is the URL of your study?
This is the link to your survey/experiment, hosted on an external platform (e.g. Qualtrics, Gorilla). This is where we will send participants when they sign up to your study.
Further information on study/ experimental software integration requirements, and how to set these up, are discussed here: What survey/experimental software is compatible with Prolific?
How do you want to record Prolific IDs?
I'll add a question to my study - if you choose this option, you'll need to add a question to the beginning of your study that asks participants for their ID. We give our participants a quick way to copy their ID for this purpose. Please note that when using this method there's a risk of IDs not being recorded accurately. For example, a participant may mistakenly miss a character from their ID.
I'll use URL parameters - if you choose this option you'll need to set up your survey tool to record participant IDs. Our article What survey/experimental software is compatible with Prolific? covers how to append parameters to the end of your URL if you wish to record some embedded data automatically using the URL. This is our recommended option.
I don't need to record these - if you choose not to record participant IDs you'll have no way of linking responses in your external study software to submissions on Prolific. If a participant has difficulties with your study or you're considering rejecting them, we will have no way of assisting you in identifying the relevant Prolific participant. We strongly advise against using this option.
