Trading API's GetItemTransactions method keeps returning "Auth token is invalid"

[midwayusa1]

Trading API's GetItemTransactions method keeps returning "Auth token is invalid" even though my token should be valid. I'm able to call other methods with the same token such as Trading API's GetSellerEvents. If I remember correctly, I was able to use the GetItemTransactions method last week. Did something change?

Hi @midwayusa1,

Error 931 indicates that the Authentication Token used in your XML or SOAP call was not recognized by the eBay Web Services authentication framework as a valid token.

For further details on the "Auth token is invalid" error, you can refer to the Knowledge Base article: https://developer.ebay.com/support/kb-article?KBid=630

I suspect I may have had multiple tokens at the same time. Occasionally the API explorer won't fetch the last token so I will get a new one. I think maybe having both of these tokens simultaneously might be causing issues>
