I need to access the eBay Merchant Integration Platform **via SFTP**. Using the web CSV upload is not an option, because I want to automate the process.

It works as I can upload products, update quantities, prices, and receive offers periodically. However, I fail to delete an inventory item (which is not the same as setting the quantity to 0, which works fine).

I tried to upload my `delete-inventory.csv` to the `store/inventory` folder on the SFTP server, but the error message in the response CSV looks as if eBay interprets the file as a 'normal' `inventory.csv`.

**My question is:** To which of the folders (e.g. `store/availability`, `store/distribution`, `store/product`) should I upload my `delete-inventory.csv` if not to the `store/inventory` folder?

Call me dumb but I'm unable to find it in the docs.

Here's my `delete-inventory.csv`:

```
SKU,Action,Channel ID,Format
test-sku,DeleteInventory,EBAY_US,FIXED_PRICE

```

And here's the eBay response CSV:

```
SKU, Group ID, Locale, ePID, Channel ID, Item ID, Status, Message Type, Message ID, Message
test-sku,,,,,,FAILED,ERROR,335101,Invalid request for SKU. Atleast one of shipToLocationAvailability or offers is required.

```

NB: The same happened when I removed the optional columns `Channel ID` and `Format` from my `delete-inventory.csv` or when I played around with optional/mandatory columns. It does not seem to be a syntactical problem.

Thanks for your help!
