Connector implementation

## Build the WhatsApp Business integration

WhatsApp template and service messages through the customer’s own WhatsApp Business Account on Meta’s Cloud API, with delivery statuses, inbound messages and opt-outs from Meta’s webhooks.

Messaging & Chatbots

*WhatsApp Business connector flow from source system to Tajo mapping and Brevo activation.*

## Implementation Overview

**Build target**

Implement a WhatsApp Business 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.

Runs as the native whatsapp-business integration (integrations/whatsapp-business) on graph.facebook.com v26.0; no vendored spec, so Code Mode stays disabled. Endpoints read from Meta’s reference pages on 2026-10-11.

## Authentication

- Keep [developers.facebook.com/documentation/business-messaging/whatsapp/get-started](https://developers.facebook.com/documentation/business-messaging/whatsapp/get-started) 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:

- Contact and identity records
- Events, webhooks, and behavioral activity
- Campaign, messaging, or audience state
- Tickets, conversations, and support context

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 WhatsApp Business, 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 WhatsApp Business. A projection is declared on a typed connector contract, and WhatsApp Business 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).
