# 4.2 Delete batch

<mark style="color:red;">`DELETE`</mark> `/documentClassification/deleteBatch`

This endpoint permanently deletes a specific batch from a document classification process.

You must provide both the `classificationId` and the `batchId` in the request body. This action is irreversible and will remove the selected batch along with all results and files associated with it.

Use this endpoint when you need to clean up or remove a specific batch without affecting the overall classification. Separate endpoints are available for deleting entire classifications or individual files.
