# Review application template attachment change

`deal_application_editor.review_attachment_change`

Review setting or removing the PDF template attached to a file question in this Portal's draft. Read get_config and open the draft first. For set, hash the exact PDF and provide filename, size_bytes and content_sha256; for remove, omit those fields. Signature blocks are unsupported. This does not stage bytes, publish, notify participants, or change submitted answer files. Review the returned effects before prepare_attachment_upload, set_attachment, or remove_attachment with this digest and revisions. This toolset requires a specific grant and is not assigned by default; request access through Support.
