The borrower-×-lender link record. There is one row per (borrower, lender) pair, and it gives you the identifiers needed to join Communications rows ([D21](/api-reference/exports/datasets/d21-communication-logs), [D22](/api-reference/exports/datasets/d22-conversations), [D23](/api-reference/exports/datasets/d23-manual-communication-logs)) back to a customer in your own warehouse.

## Sample row

```json theme={null}
{
  "public_id": "7c1e9a02-5d38-4b6f-9012-a3e8c5d7b461",
  "customer_reference_id": "CUST-2026-00482",
  "first_name": "Khalid",
  "last_name": "Al-Mutairi",
  "preferred_language": "ar",
  "passport_number": "****2206",
  "dob": "1990",
  "comms_pipeline": "STANDARD",
  "do_not_contact": false,
  "dispute": false,
  "created_at": "2026-02-14T07:01:09.330Z",
  "updated_at": "2026-05-15T10:22:48.715Z"
}
```

<Warning>
  `passport_number` and `dob` are always returned masked. `passport_number` shows only the last 4 characters; `dob` is reduced to the 4-digit year. The raw values are never exposed by this endpoint.
</Warning>

## Pagination characteristics

This dataset is **direct** — filtered to your tenant by `lender_id` on the collection itself, so each page returns a constant number of rows until the last page.

## Use cases

* Build the foreign-key bridge between Communications data and your customer master.
* Resolve borrower display names and language preferences.
* Track customer-liveness or dispute flags.
