# Mailchimp Connector

[Set Noa](https://tajo.io/set-noa/)

Connector status: In progress Being built. Not verified yet.

| Source field | Destination field | Sample value |

Tajo’s Mailchimp connector is in progress. The code exists, but it has not yet passed a run against a live Mailchimp account.

## What the code does

- Reads audiences and their members with status, merge fields and tags, plus segments, interest groups, signup forms and surveys.
- Reads e-commerce stores, customers, orders, carts, products and promo codes.
- Reads campaigns with their content and reports, templates, landing pages, classic automations and SMS campaigns.
- Adds or updates one audience member, adds or removes a member’s tags, and registers an audience webhook for changes such as subscribes, unsubscribes and profile updates.
- Treats a member’s status as marketing consent: an unsubscribed or cleaned member is a suppression.

## Not available today

- Migration of automations, templates or campaigns into Brevo
- Engagement metrics written to contact attributes
- Real-time sync. The audience webhook exists in code and has not been verified.

## Open-Source Implementation Map

This section is derived from official or public repository material discovered for the Mailchimp connector. Use it as the engineering companion to the setup guide above: it shows where the API surface lives, what implementation assets exist, and how Tajo should translate them into reliable Brevo sync behavior.

### Tajo Revamp Checklist

- Keep authentication setup aligned with the vendor docs and the public repository’s current API shape.
- Map primary resources into explicit Tajo sync objects with stable external IDs.
- Prefer cursor-based or updated-at incremental sync where the API exposes it; otherwise document the fallback.
- Treat webhook handlers as idempotent and replay-safe, especially for order, contact, ticket, and campaign events.
- Capture pagination, rate limits, retry headers, and partial-failure behavior in connector smoke tests.
- Keep examples small and runnable against sandbox or test-mode accounts.
