Per Diem Rates - API and CSV file download (inventory.data.gov)

Hi,

I have a couple questions related to the Per Diem Rates information that inventory.data.gov provides.

1. We have been downloading your Per Diem rates csv file from the following links in the recent past, but the link now (I have been trying since yesterday) gives me a "404 Not Found".
This was the link we have been using in the past: **_https://inventory.data.gov/dataset/ad729937-b245-4eec-a88d-b72eb36d8106/resource/8ea44bc4-22ba-4386-b84c-1494ab28964b/download/perdiemreimbursementrates.csv_**

Is there another/changed link for the older csv version?

I am aware of the other page/link which gives an xls file: https://www.gsa.gov/travel/plan-book/per-diem-rates/per-diem-files but the data layout is completely different, and more so it doesn't give Zip Code related information. On the other hand, the csv Version gives the information in the way it can be used for what is needed. It is just not the data formats (csv v/s xls) that is the issue for us, but the data content as a whole that is an issue with the xls file.

2. We have also been using the **Per Diem API** to get rates. This is the link we have been using: **_https://inventory.data.gov/api/action/datastore_search?resource_id=8ea44bc4-22ba-4386-b84c-1494ab28964b&limit=300000&filters=%7B%22FiscalYear%22:%222019%22,%22Zip%22:%2292692%22%7D_**
This API has been having some issues since the last couple days that we have been monitoring it: **_"Access denied: User not authorized to read resource 8ea44bc4-22ba-4386-b84c-1494ab28964b", "__type": "Authorization Error"_**

And today it has been giving a "Internal Server Error" off and on.

We are aware that GSA is now offering a new API for the Per Diem rates. **_https://open.gsa.gov/api/perdiem/_**

We would like to know if the older API (from inventory.data.gov) will continue to be offered for Customers who would like to use it.

Can you please help or guide me to the some contact at inventory.data.gov who can answer the related questions?

Thank you!
