# Field-level modification log for a LEI record

`GET /api/v1/gleif/audit/{lei}`

Return the audit trail of field-level changes applied to a LEI record (and its linked relationship records). Each entry carries the modified field (XPath pointer into the CDF XML schema), modification type (`INSERT`, `UPDATE`, `DELETE`), prior value, new value, and change date. Useful for detecting entity status flips, address changes, renewal events, and ownership restructurings.

## Path parameters

- `lei` string, required — 20-character LEI whose field-modification log is returned.

## Query parameters

- `page_size` integer — Entries per page (1 to 200).
- `page_number` integer — 1-based page number.

## Response `200`

Field-modification entries for the LEI record, newest first, with pagination block.

- EnvelopeGleifAuditPayload

    - `source` string, nullable — Identifier of the primary upstream source used for this response.
    - `attribution` string, nullable — Human-readable attribution mandated by an upstream source (e.g. a securities regulator or self-regulatory organization).
