Hello,
I imagine this might be a big feature to ask, but I think it would be awesome if there were a Prolific API.
A way we could communicate with Prolific from our R/Prolific/other scripts to program things like:
And maybe other things that I can’t think of right now.
Hey @Samuel_Dupret, this is a great idea that’s come up before. We’re currently looking at working on this. We know how much easier it will make using Prolific.
I’ll let you know as soon as I have concrete updates on this 
@Samuel_Dupret You asked and we listened!
Check out @Andrew_Arderne’s guide 
This is a very early first development, so do let us know your thoughts 
Wow, that’s awesome! Thank you @Josh and @Andrew_Arderne !
I had a go at it with R and I managed to bulk approve my study. Wonderful I am looking forward to be able to do bonuses that way.
Once you can authenticate and you know your study id works, you can then use the following API to
bulk pay bonuses. This process takes 2 steps, creating the bulk processing data and then paying it out.
https://www.prolific.co/docs/api-docs/public/#tag/Bonuses/paths/~1submissions~1bonus-payments/post
You need to use the following schema for your data in the --data-raw, the following shows an example of this POST data. The csv_bonuses contain the participant_ids that you should have from your survey tool.
{
"study_id": "61000180997ce18e0cd801b3", \\ taken from study url
"csv_bonuses": "60ffe5c8371090c7041d43f8,0.20\n60ff44a1d00991f1dfe405d9,0.20"
}
csv_bonuses structure: String(participant_id comma amount new_line)
The line below shows an example of this CSV format.
60ffe5c8371090c7041d43f8,0.20\n60ff44a1d00991f1dfe405d9,0.20\n610001c69ef2254561beee980.30
Running that curl command should return similar data to this, the id is important here and will be used in the next step.
> {
"id": "61015b057bd72ddc7244edb9", // <-- used in next step as bulk_payments_id
"study": "61000180997ce18e0cd801b3",
"amount": 40.0,
"fees": 0.0,
"total_amount": 40.0,
"vat": 0.0
}
Now that everything is setup, copy the bulk_payments_id and replace it with the url below
https://www.prolific.co/docs/api-docs/public/#tag/Bonuses/paths/~1bulk-bonus-payments~1{id}~1pay~1/post
If this works it should return the following message, you can also see the amount shown on the study page.
> "Successfully processed bonus payments."
Awesome! I don’t have bonus payments to do right now and I am off for a week but I will give that a try when I get back.
Hey! I’m affiliated with PsychoPy/PsychoJS/Pavlovia. We’ve seen other devs create “study portals” to manage Pavlovia, like VESPR. I wondered if we could extend that idea to Prolific and then discovered this thread. The web API already covers the most important use cases; cool
I’ve got a feature request/suggestion: could I request an API key? I.e., some auto-generated string that the researcher can copy-paste from Prolific into another application. Then the other application doesn’t need to know the researchers’ password for authenticating itself to the web API.
Hi @Thomas_Pronk ,
I am a backend engineer at Prolific.
We are actively thinking of offering an API key to increase security when using the API.
And we have also been looking at PsychoPy and wondered how could we make it easy to integrate with Prolific.
Would you like to talk with us?
Hi @Jonas_Anso, nice to meet you!
Yes, I’d love to. Actually, I found out that Jon (our CEO) is already planning a web API meetup. I guess we’ll talk soon
Cheers, Thomas
