# Census (Fivetran Activations)

> Census is a reverse ETL / data activation platform that syncs modelled data out of a cloud data
> warehouse into 200+ business destinations (CRM, marketing automation, advertising, support,
> success). Data teams define SQL models, datasets and segments against the warehouse and Census
> keeps the destination in sync. Census was acquired by Fivetran and now ships as **Fivetran
> Activations**: the product docs live on fivetran.com/docs/activations, while the API is still
> served from app.getcensus.com.

Source: this repository's apis.yml and artifacts, plus the Activations section of
https://fivetran.com/llms.txt. Census does not publish an llms.txt of its own on any getcensus.com
host (www.getcensus.com/llms.txt -> 404; developers.getcensus.com/llms.txt -> SPA catch-all).

## API

- [Census Management API reference](https://fivetran.com/docs/activations/rest-api/api-reference/introduction): Two Bearer-authenticated REST APIs over one /api/v1 surface — Workspace APIs (syncs, sync runs, sources, models, segments, datasets, topics, tables, destinations, destination objects, connect links, webhooks) and Organization APIs (workspaces, workspace users, workspace variables).
- Base URL (US): `https://app.getcensus.com/api/v1`
- Base URL (EU): `https://app-eu.getcensus.com/api/v1`
- [Authentication](https://fivetran.com/docs/activations/rest-api/api-reference/introduction/authorization): HTTP Bearer. Workspace API key for Workspace APIs; Personal Access Token for Organization APIs.
- [Pagination](https://fivetran.com/docs/activations/rest-api/api-reference/introduction/pagination): `page`, `per_page` (default 25, max 100), `order` (asc|desc); responses carry a `pagination` object.
- [Developer hub](https://fivetran.com/docs/activations/rest-api): API reference, Powered-by-Fivetran embedding, Terraform, Custom Destinations, Partner Destinations.
- [Postman collection](https://www.postman.com/getcensus/workspace/census-api/overview): public Postman workspace "Census API" covering the API endpoints.

**No OpenAPI.** Census publishes no OpenAPI, Swagger, GraphQL SDL or AsyncAPI document for this API.
The per-endpoint reference pages are one-line stubs that link to
`https://fivetran.com/assets-docs/openapi/file_v1.yaml`, which is Fivetran's **core** REST API spec
(`servers: https://api.fivetran.com`, basicAuth, `/v1/connections…`) and contains no Activations
paths at all — it does not describe this API.

## Events

- [Sync Lifecycle Webhooks](https://fivetran.com/docs/activations/syncs/sync-monitoring/sync-lifecycle-webhooks): 7 events — `sync.triggered`, `sync.started`, `sync.completed`, `sync.success`, `sync.failed`, `sync.alert.raised`, `sync.alert.resolved`. Payloads always carry `workspace_id`, `sync_id`, `sync_run_id`, `event`. A one-time signing secret is issued at creation.
- Webhooks are also managed through the Management API (`workspace-apis/webhooks`).
- [Create a topic event](https://fivetran.com/docs/activations/rest-api/api-reference/workspace-apis/sources/topics/create-a-topic-event): push events into Activations as a streaming source.

- 2026-06-17 — "Streamlining Fivetran Activations": workspaces are going away and activation syncs will be regrouped into individual activations "in the UI and API, exactly like connections in Fivetran today". A forthcoming breaking change to this API.
