This invoice has already been paid.

Recommended Posts

I'm hoping someone on here can help me. I'm getting really close to finally finishing my store so I've tried making a purchase through the PayPal Sandbox, but when I try I get the error message...

This invoice has already been paid. For more information, please contact the merchant.

 

Here's my setup...

PayPal Website Payments Standard

Enable PayPal Website Payments Standard: True

E-Mail Address: me@mydomain.com

Payment Zone: --none--

Set Preparing Order Status: Preparing [PayPal Standard]

Set PayPal Acknowledged Order Status: Processing

Gateway Server: Sandbox

Transaction Method: Sale

Page Style: MyStyle

Debug E-Mail Address: business@mydomain.com

Sort order of display: 0

Enable Encrypted Web Payments: False

Your Private Key:

Your Public Certificate:

PayPals Public Certificate: /usr/bin/openssl

Your PayPal Public Certificate ID:

Working Directory:

OpenSSL Location: /usr/bin/openssl

 

I've set up a PayPal Sandbox account as me@mydomain.com

Within this I've then setup a business account business@mydomain.com and a customer account customer@mydomain.com

 

When I click through my basket and go to confirm order, it is launching the PayPal site fine and asking me to log in. I log in using my customer@mydomain.com address and go to the Pay Now button and then it goes to the page with the error This invoice has already been paid. For more information, please contact the merchant.

 

I really don't know what is causing this or how to get around it. Obviously I can't go ahead with my site until I know that the actual purchasing process will work without issue.

 

Any advice or guidance would really be appreciated.

 

Thanks

 

Steve

this can be only if you have more than one website using the same PayPal account, to fix the issue, you can disable to check the invoice numbers in PayPal account settings (on PayPal website).


Please read this line: Do you want to find all the answers to your questions? click here. As for contribution database it's located here!

8 people out of 10 don't bother to read installation manuals. I can recommend: if you can't read the installation manual, don't bother to install any contribution yourself.

Before installing contribution or editing/updating/deleting any files, do the full backup, it will save to you & everyone here on the forum time to fix your issues.

Any issues with oscommerce, I am here to help you.

I can repeat that it's not PayPal module issue!!!

Try changing the E-mail address for your shop in the module from me@mydomain.com to your sandbox business account, business@mydomain.com.

Looks like it was an issue with how I'd set the accounts up. Using the paypal assisted method rather than setting them up manually has fixed it.

 

Thanks for your help guys
