# Glossary

> Definitions for terms used across Research Desk documentation.

## A

**Abandon** — Respondent exited without a recognized redirect outcome. High abandon rates throttle traffic and may pause a project.

**ACTIVITY** — Research Defender check that tracks a respondent's survey-taking rate across the market research ecosystem.

**Auto-accept** — System automatically accepts unprocessed completes after the reconciliation deadline, making them billable.

## B

**BCPI (Buy Price)** — Cost per interview Research Desk charges you for supplier traffic on a source. Adjustable during fieldwork.

**Buy Sample** — UI label for creating an **Internal Source** that purchases sample from Rep Data's integrated supplier network.

## C

**Calculation Type** — How quota progress is measured on a source: Completes, Survey Starts, or Hybrid.

**Client CPI (Sell Price)** — Price you charge your end client per complete, entered on the survey.

**COMPLETE API** — Server-side respondent validation option for accounts with enhanced redirect security.

## D

**Defender term** — Respondent blocked by Research Defender (SEARCH, ACTIVITY, or REVIEW) before reaching your survey. Recorded as a security outcome.

**Draft** — Project, survey, or source status indicating configuration in progress; should not receive production traffic.

## E

**Entry link** — Survey URL with `[%RDUD%]` that Research Desk uses to send respondents into your survey platform.

## H

**Hashing (redirect)** — SHA-256 or SHA-512 validation on return redirects using secret key (`sk`) and hash parameter (`hk`).

**Hybrid** — Calculation type combining completes and survey starts for quota measurement.

## I

**Internal Source** — Self-serve sample purchase via Buy Sample from Rep Data's supplier network.

**IR (Incidence Rate)** — Percentage of entrants expected to qualify for and complete the survey.

## L

**Live** — Status indicating active fieldwork. Surveys and sources in Live status receive respondent traffic.

**LOI (Length of Interview)** — Expected survey duration in minutes. Misaligned LOI affects CPI and traffic.

**L2 Voter Verified** — Qualification targeting respondents pre-matched against L2's voter database.

## M

**Manual Source** — Source type (Add Supplier) for routing traffic from your own supplier contracts through Research Desk.

**MAIN stream** — General population traffic stream without sub-quota targeting.

## O

**ORDUD** — Original RDUD from a prior study, passed when [recontacting respondents](/research-desk/guides/11-recontact-respondents).

**OQ (Over-quota)** — Respondent attempted entry after a quota cell was full. `inbound_code=4000` on redirect.

**Out-of-field (OOF)** — Project end date and time; used by [traffic controls](/research-desk/guides/15-traffic-controls) for pacing.

## P

**Pacing** — [Traffic control](/research-desk/guides/15-traffic-controls) that spreads sample delivery across the field window.

**PII** — Personally identifiable information captured in the survey (email, phone, etc.).

## Q

**QUOTA stream** — Stream with demographic or behavioral targeting for a quota cell.

**Quota cell** — Intersection of qualifications a respondent must match to count toward a quota target.

**REVIEW** — Research Defender pre-survey open-end quality check.

**Reconciliation** — Process of accepting or rejecting completes before billing. See [Reconciliation guide](/research-desk/guides/07-reconciliation).

**Security** — Respondent outcome for quality/fraud termination. `inbound_code=3000` on redirect.
