# ODK Central integration

> What this integration supports through the Unified.to API, by object. Live data: `GET https://api.unified.to/unified/integration?type=odkcentral` with your workspace API key (or Core MCP `list_unified_integrations` with `type: "odkcentral"`). All integrations: https://docs.unified.to/integrations.md

## Overview

- **Type:** `odkcentral`
- **Categories:** [Forms](https://docs.unified.to/forms/overview.md), [Tasks](https://docs.unified.to/task/overview.md), [HR & Directory](https://docs.unified.to/hris/overview.md), [Passthrough](https://docs.unified.to/passthrough/overview.md)
- **Website:** https://getodk.org
- **Vendor API docs:** https://docs.getodk.org/central-api/
- **Launched:** 2026-11-10

## How end users connect

- **API key** entered by the end user: `Email`, `Password`, `ODK Central Host`, `Project ID`
    - The email address of an ODK Central Web User. The User needs a role that can read the projects, forms and submissions you want to use (e.g. Project Manager or Administrator).
    - The password of that Web User. Servers that use single sign-on (OIDC) do not accept passwords over the API.
    - The host of your ODK Central server, e.g. central.example.com (no https:// and no path).
    - The numeric ID of the ODK Central project whose forms and submissions to use. It is the number after /projects/ in the project URL.
