PayPal - Sandbox API credentials not accepted
So, I am currently setting up PayPal Escrow (in the Sandbox) and have the following issue:
While regular payments work (e.g. buying credits), the Escrow payments do not. I am using the proper "NVP/SOAP Sandbox API Credentials" as they are clearly denoted on my PayPal developer site. I use the exact username, passwort and signature right under the API credentials title.
My account email in the beginning of the HireBee PayPal settings (not the API) is my regular business account email. I have clicked the checkbox to use the sandbox account in HireBee settings.
The Error message in my Dashboard from Hirebee is:
"Added user '************' with email '*******' as receiver
The following error ocurred while trying to make the pay request: "Authentication failed. API credentials are incorrect.""
Inside my Paypal developers dashboard I see no notifications so I guess it failed on the login. I am at a loss, does anyone know the answer?
