# REST API

<Update label="2026-08-17">
  ### Added

  * [Write record attribute values](https://docs.attio.com/rest-api/endpoint-reference/records/write-record-attribute-values)
    and
    [write list entry attribute values](https://docs.attio.com/rest-api/endpoint-reference/entries/write-list-entry-attribute-values)
    replace the full value history of one attribute, for migration of historical data from other
    systems. Webhooks and workflow triggers do not fire for these writes. Both endpoints are in beta.
  * [Merge two records](https://docs.attio.com/rest-api/endpoint-reference/records/merge-two-records)
    combines two records of the same object into one new record. The values of the primary record have
    precedence. This endpoint is in beta.
  * [List emails](https://docs.attio.com/rest-api/endpoint-reference/emails/list-emails) gives the
    metadata of emails from the connected mailboxes in your workspace. Email content is never
    returned. This endpoint is in alpha.
