# Outlook Calendar Connector

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

Connector implementation

## Build the Outlook Calendar integration

Calendar events and attendee data for webinar, meeting, lifecycle, and follow-up automation in Brevo.

Productivity

*Outlook Calendar connector flow from source system to Tajo mapping and Brevo activation.*

## Implementation Overview

**Build target**

Implement an Outlook Calendar 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.

**Primary surface**

github.com/microsoftgraph/msgraph-metadata

Useful for event-triggered Brevo journeys and meeting follow-up.

## Authentication

- Use [github.com/microsoftgraph/msgraph-metadata](https://github.com/microsoftgraph/msgraph-metadata) to generate or validate typed API clients and request models.
- Keep [learn.microsoft.com/en-us/graph/outlook-calendar-concept-overview](https://learn.microsoft.com/en-us/graph/outlook-calendar-concept-overview) 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:

- Commerce, payment, or subscription objects
- 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 Outlook Calendar, 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 Outlook Calendar. A projection is declared on a typed connector contract, and Outlook Calendar 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).
