Automate everything with our API

From lightweight automations to full system-to-system integrations, our open API lets you scale your studies and apply your own business rules to automate data collection and repetitive tasks like approving submissions.

Developer documentation

Scale

Collaborate with others, manage and program projects and participant lists.

Automate

Automate repetitive tasks and enable event-driven communications and actions.

Control

Enable full system-to-system integration with your tech stack, your way.

Start with Study API

Create, update, and push studies live

Study API is your starting point for integrations. Scale and spin out multiple studies at once. Automate every part of your study and data collection. Or enable a system-to-system integration of Prolific into your existing tech stack.

Be first to experience all our latest capabilities

We build API-first, so our API customers are always the first to experience, and benefit from, new features and capabilities.

When you, or your business, have specific criteria for submissions, use this API to enforce those and remove unsuitable submissions without any human intervention.

Submissions

Approve and reject submissions programmatically

Use the Bonus API when participants or taskers have gone above and beyond. Or when you need to incentivize preferred respondents to take part in longer-running studies.

Bonuses

Pay bonuses and reward automatically based on key criteria

As simple as it sounds—Messages allows you to communicate with participants from within your own ecosystem.

Messages

Send and receive messages to participants

Create multiple workspaces for different projects or teams, organize studies into projects, and add multiple users or collaborators.

Workspaces

Organize, collaborate, and scale your team

Run basic surveys of up to 5 questions with data collection via our API. Useful for quick pre-screening or identifying custom audiences.

Surveys

Create quick pre-screening studies

Create and manage (anonymized) lists of participants or taskers. No need to find them manually—just save groups and re-use.

Participant Groups

Create custom lists of participants for studies

Get secure, self-serve access with unlimited API tokens

Once you're signed up simply head to settings in product and create as many API tokens as you like to access our API.

Don’t learn new tools. Use the ones you know.

Prolific works seamlessly with all your usual tools—just add a link or integrate via our API.

View all integrations

Create scalable and resilient systems

Create loosely coupled, modular systems that respond to specific events, promoting a more scalable and resilient architecture.

Get real-time notifications

Receive instant notifications about events so your integrations can react and synchronize in real-time.

Reduce resource usage

With apps only being notified when relevant events happen, you reduce unnecessary network traffic, server load, and resource consumption—driving efficiency and scalability.

Case Studies

See how our customers scaled their studies with our API

Light API integrations

Duke Moral Lab use API interactions to manage studies, workflows, and participants programmatically. Instead of setting up multi-part studies and re-inviting participants manually, they now programmatically set up follow-up studies and pay bonuses for qualified participants based on study outcomes. It saves them 2 hours on each pilot study, unlocking their ability to scale.

System-to-system B2B Partner

Dallinger has integrated with Prolific to automate access between the two tools, so researchers using Dallinger can run experiments end-to-end. Individual researchers still create their own account with Prolific, but can streamline, automate, and scale their experiments through Dallinger without having to set up participant recruitment manually.

Full product integration B2B2C

By enabling a full API integration, Useberry gives direct access to Prolific’s participant pool and high-quality data via their product—without users needing a separate Prolific account. This full product integration has been developed in partnership with Prolific to deliver a seamless experience to researchers who use this popular and powerful tool.

Enhance your product by integrating Prolific

Put our unrivaled participant pool at the heart of your product. Fully integrate Prolific into your tech stack via our API to give your customers seamless access to our platform and product.

Partner with us

Stability you can count on

We use the same API ourselves. That means if there’s a problem with the API, our platform will experience it too, so our top priority will be to fix it.

Throughput optimization

Control the flow of submissions to your study via throughput optimization.

Multi-submissions

If you can control the uniqueness of your tasks, then set up multi-submissions to allow a participant to take your study over and over. Thresholds configurable.
