# Ingest Documents via File

A file can contain either sale documents or purchase documents. Each document can contain one or more document line items. Each document line item represents one row in the file.

A file can contain documents belonging to one or more GSTINs belonging to the same PAN.

To upload a file, the following 4 APIs are to be used in the same order:
