Bulk-load Q&A rows into one knowledge base from a CSV upload (the document plane; the singular /knowledge-base path). Admins only (knowledge_base:write). The CSV header must be exactly question,response; mode=replace (default) overwrites the KB’s rows while mode=append adds to them. Scope knowledge_base:write.

Body
multipart/form-data
UTF-8 CSV upload (a UTF-8 BOM is tolerated). Header row must be exactly question,response, with at least one data row and no extra columns; max 5 MB.
Target knowledge base id. Required (a 400 is returned if absent) and must reference an existing KB in the caller's workspace (else 404).
replace overwrites the KB's existing rows; append adds to them.
Available options:
replace, append Response
Rows ingested. ingested is the number of Q&A rows written, echoing the effective mode and target knowledge_base_id.
