Payments failing “BAD_INPUT_ERROR”

Just FYI I’m testing on my sites to see.

I assume you are on the current version, not that any of that code has changed for a good while.

Hi. I am on Version 5.7.5 which looks to be the latest version. I am getting notification emails about the testing sends but nothing showing the payments have completed.

Ok I have tested this and it does work fine on my systems.

A bit of research found that people got the same error inconsistently when their email address had a trailing space.

I just tested by adding a space to my email and indeed the error occurs.

I know you said you ‘reset’ and ‘readded’. Can you double check that maybe but cut and paste you introduced a space. i.e. delete and manually re-enter your address.

Just looking at the code, other possible places you may have inadvertently added spaces would be on the Thankyou URL & Cancel URL if you are using those.

Just FYI, unless you specify not to – the emails & logs happen when the form is submitted, and not when payment has completed, that is the purpose of IPN (Instant Payment Notification) processing if you enable that an suppress payments until actually paid.

The space on the email appears to have been the issue. I removed the space and everything is working now. Thank you.

Brilliant.

I have already added code to strip out errant spaces ready for the next release. Thanks for helping pin down this issue.
