Inventory Client - ACCESS DENIED

[sdaeric19]

Hey guys,
I'm struggling with the Inventory Client.

My goal is to pull current inventory of all my ASINs.

My tokens are fine as they work with order, sales, product clients

Here's my code

from sp_api.api import Orders, Reports, Sales, ProductFees, Products, Catalog, Inventories
from sp_api.base import SellingApiException, Marketplaces, Granularity
from datetime import datetime, timedelta, timezone
from sp_api.base.InventoryEnums import InventoryGranularity


# Inventory API
try:
    res = Inventories(marketplace=Marketplaces.GB).get_inventory_summary_marketplace(granularityType=InventoryGranularity.MARKETPLACE,
                                                                                     granularityId="A1F83G8C2ARO7P",
                                                                                     marketplaceIds="A1F83G8C2ARO7P")
    print(res.payload)  # json data
except SellingApiException as ex:
    print(ex)

However I'm getting access denied error on this and Catalog Client. Please can you help me?

[{'message': 'Access to requested resource is denied.', 'code': 'Unauthorized', 'details': ''}]

The token has to work with FBA, the other endpoints are unrelated to this. Can you check if the box for FBA is ticked in sellercentral.

@sdaeric19 Hi did you find a solution here, I am going through the same issue now

If that's the inventory summaries endpoint you're having problems with, and you're trying to get them for a Marketplace other than US, it won't work at the moment because Amazon doesn't support this yet for non US marketplaces.
I've heard that this was to change, but that was some months back already...

oh, okay, makes sense then, I am trying for DE.

Hey @saleweaver were there any developments on this front? I'm having the same problem as others, with the error saying that I am unauthorized to access the requested resource. As an example, this request:

res = Inventories(credentials = credentials, marketplace=Marketplaces.US).get_inventory_summary_marketplace(marketplaceIds=[Marketplaces.US.marketplace_id])

Returns this error:

[{'message': 'Access to requested resource is denied.', 'code': 'Unauthorized', 'details': ''}]

The Orders endpoint on the other hand works perfectly fine with the same credentials. It shouldn't be an issue of the app permissions, since I ticked off the Inventory box (as well as all the other boxes for that matter).

The stores I'm handling operate only in the US, so region also shouldn't be a problem.

Just a quick update here: I managed an ad-hoc solution for my purpose using the reports API, which works.

When using the reports API, I've noticed that I had to request specifically FBA inventory reports rather than regular inventory reports. Might it be related to my issue regarding the Inventory API queries?

Thanks!
