eBay Auth'n'auth token's not functioning

[chris.k11]

Hello,

I'm just getting started using the eBay API and have run into some frustrating roadblocks using the Trading API. 

When attempting to make a call to the Trading API using an Auth'n'auth token, I consistently receive an ErrorCode 931 (full message below). I first encountered the issue when trying to make a call from my own application but I run into the same error when using the API Explorer directly on the eBay developers program site. All the actions I am taking are through the Sandbox, not Production. As far as I can tell I am correctly generating tokens (User Tokens Page -> Sign in to Sandbox -> Agree -> Copy Token. All the actions I am taking are in the Sandbox environment, not Production.

<Errors>
<ShortMessage>Auth token is invalid.</ShortMessage>
<LongMessage>Validation of the authentication token in API request failed.</LongMessage>
<ErrorCode>931</ErrorCode>
<SeverityCode>Error</SeverityCode>
<ErrorClassification>RequestError</ErrorClassification>
</Errors>

Any thoughts are greatly appreciated.

Same here. Im using an app that is years old so im wondering if something has broken with the token generation

Try wrapping the token in double quotes.
I had a similar issue and it sorted it see this link https://github.com/hkonnet/laravel-ebay/issues/26

I'm having the same issue. Unfortunately wrapping the token in double quotes did not solve the problem.

Update: I tried using OAuth instead of Auth'n'Auth and it worked.
