Paypal Express - Incorrect Credentials

[old_guy]

Hi all,
Paypal Express is showing an error related to the headers.
Says incorrect api details, but these have been verified by paypal.
Is there a problem with the extension?
Any fixes or suggestions welcome.

Regards

Hi.

In PayPal you have two modes: Test and Live
for each mode used different API credentials

Hi All,

The problem was between the keyboard and the seat. 

The cause of the error was a trailing space on the api username.

The joys of copy and paste 

Thanks for the help, the sandbox hint was really useful

Same issue here, I'm glad you were there before me, I wouldn't have thought of looking for a trailing space in the API Cert. fields.....thanks
