# Fivetran Activations Connector

Connector status: Planned Not built yet. Tajo does not run this connector today.

Connector implementation

## Build the Fivetran Activations integration

Reverse-ETL and operational analytics platform for syncing warehouse audiences and traits into Brevo.

Reverse ETL

*Fivetran Activations connector flow from source system to Tajo mapping and Brevo activation.*

## Implementation Overview

**Build target**

Implement a Fivetran Activations connector that authenticates to the vendor surface, normalizes source records in Tajo, and activates eligible data in Brevo.

**Current status**

Treat this as an implementation guide. Build and validate the auth, mapping, sync, and operations paths before production use.

Renamed Fivetran Activations after Fivetran acquired Census (formerly Census; slug retained). Already exists in the customer catalog; added to v2 for connector selection.

## Authentication

- Keep [fivetran.com/docs/activations](https://fivetran.com/docs/activations) linked from the connector runbook so operators can confirm vendor behavior during incidents.
- Store credentials per Tajo workspace and keep tenant-specific secrets out of connector configuration files.
- Add a credential smoke test that verifies read access to a harmless resource before running backfills or enabling webhooks.

## Data To Sync

Start with these inferred data domains, then confirm exact vendor resources and permissions from the source documentation:

- Events, webhooks, and behavioral activity
- Custom objects and operational metadata

The connector should make source records idempotent by keeping a stable key such as a vendor object ID, email address, event ID, ticket ID, order ID, or campaign ID. If the vendor only exposes list APIs, Tajo should store the cursor strategy and replay policy explicitly.

## Sync Shape

No typed contract exists for Fivetran Activations, so the direction of each resource and its conflict handling are not recorded. Direction is declared per resource on a connector contract; see the [connector catalog](https://tajo.io/docs/connectors) for how contracts are promoted.

## Mapping To Tajo/Brevo

No Brevo projection is recorded for Fivetran Activations. A projection is declared on a typed connector contract, and Fivetran Activations does not have one yet, so this page will not state a mapping it cannot source.

The conventions that apply to every connector — stable external IDs, normalization, backfill and sync strategy, error handling, and the builder checklist — are documented once under “Applies to every connector” on the [connector catalog](https://tajo.io/docs/connectors).
