Customers API

Retrieve customer data and interaction timelines.

List customers

GET /api/v1/customers
Authorization: Bearer <token>

Returns the top 100 customers sorted by lastSeen (most recent first).

Get a customer

GET /api/v1/customers/:id
Authorization: Bearer <token>

Returns the customer profile along with their touchpoints.

Customer timeline

GET /api/v1/customers/:id/timeline
Authorization: Bearer <token>

Returns all touchpoints for this customer ordered chronologically (ascending). Each touchpoint includes the action, channel, campaign attribution, and timestamp.

Dedupe duplicates

POST /api/v1/customers/dedupe
Authorization: Bearer <token>
Content-Type: application/json

Merges duplicate Customer nodes by email. Supports a ?dry_run=true query param that returns the merge plan without applying it.

The resolver picks the canonical record for each duplicate group by (1) presence of cio_id, (2) edge count, (3) lexicographic id as the tiebreaker. All edges from dupes re-point to the canonical, then the dupes are deleted. Idempotent. Running it again on a clean workspace is a no-op.

Use this once after the Supabase 1000-row-cap pagination fix if you ran syncs on a pre-fix workspace and see suspiciously high Customer counts.
