This endpoint handles the initial inventory upload for a taxpayer in phased batches (up to the configured product limit per request). Products are first saved into a staging area and only processed when the last batch is received. Successfully uploaded items are classified as either mapped (matched to master products) or unmapped (requiring manual mapping). However, uploaded products are not automatically added to the taxpayer’s warehouse inventory. The taxpayer must log into the portal, navigate to Inventory Management → Initial Inventory Mapper, and click Synchronize Now. If all products were automatically mapped, they will be no need for mapping only synchronization; otherwise, the taxpayer must first manually map unmapped products and then synchronize. Synchronized products go through an approval process before becoming visible in the warehouse inventory.
Note: The initial inventory process is a one-time operation — once a taxpayer uploads their initial inventory, they cannot perform this upload again.
