# EXT:interest {#start}

-   *Version:* release
-   *Language:* en
-   *Description:*

    REST and CLI API for adding, updating, and deleting records in TYPO3. The
    extension tracks relations, so records can be inserted in any order. Uses
    remote ID mapping so you don't have to keep track of what UID a record has
    gotten after import. Data is inserted using backend APIs as if a real human
    did it, so you can can inspect the record history and undo actions.
