Embed a panel of 4.3M+ research participants into your research platform.
Your technology plus our real people: that's the future of research.
Research platforms built on the Respondent panel.
When 4.3M+ verified participants live inside your product, your customers recruit, screen, schedule, and pay without ever leaving - and your software does far more than it could on its own.
Live"The feedback from customers has been awesome. Our customers love being able to recruit their customers and non-customers as part of the same study."
Live"The Respondent API is one of our best recent investments. Our customers now have access to a global panel of survey participants - and they're happy about its speed and depth."
Live"Your API is the most robust. The B2B pool is much broader. For any company trying to create a participant integration, Respondent is cream of the crop."
Our panel will be your fastest-ever feature build.
Add our panel to your platform in as little as two weeks - connect endpoints in staging, build the screens, connect billing, and push live. We stay focused on panel building; you stay focused on the research experience.
Quality participants, no compromises.
Real people, real fast. We own the relationship with every panelist - work-email verified, LinkedIn matched, ID-checked. Your customers get verified participants, not aggregated quant panels.
- 4.3M+ verified participants
- <1% fraud rate (industry: 8–22%)
- B2B, B2C, healthcare, niche roles
Your brand on the surface.
One of the only panels comfortable being invisible. Embed recruitment, screeners, scheduling, and payouts under your own UI. Your customers stay in your product end-to-end.
- Screeners in your own UI
- Pass-through scheduling
- Programmatic incentive payouts
We don’t compete with you.
Like AWS for servers, we want to be the participant layer underneath the research industry. We’re 100% focused on panel building - no interest in shipping research tooling that competes with our partners.
- Wholesale recruit-fee rates
- Dedicated partner manager
- Co-marketing if you want it
Seven endpoints. One recruitment workflow.
Projects, screeners, responses, invites, payouts, webhooks.

}
}
}Five webhook events for the full lifecycle.
One URL per team receives every event. Payloads are signed, each delivery has a uuid, and failed calls retry up to five times.
How the API fits your customer workflow.
Same four-step lifecycle the dashboard runs. Your UI wraps it; we handle the panel underneath.
Create project.
Create your study with your chosen methodology.
Screen & recruit.
Filter and screen participants using matching algorithms, then recruit them.
Interview or survey.
Schedule, message, and interview or survey chosen participants.
Pay participants.
Pay out incentives when sessions are completed.
Boring on purpose. Where it matters.
The API inherits Respondent's security and compliance posture — the same SOC 2, GDPR, and CCPA controls, and the same payment rails. It's another front door to the panel you already trust.
