Sandbox Authentication failed SOAP

[Arun_Sivashanka]

Hi-

I just tried to access the SOAP API from my application and I'm getting the 20014 "Authentication failed" error (below). The strange thing is that when I put in production credentials it works, so I think the encryption key is correct. Is there anything else that I might have missed for the sandbox API access?

Thanks!

Hi Arun,

Did you update the endpoint to reflect your Sandbox's endpoint URI?

Hi Kenny-

Thanks for the response. I did change the endpoint in our app if that's what you mean. I used the endpoint that was in the admin -> Web Services -> SOAP API section of the sandbox.
