How do I test the HTML Unsubscribe button in sandbox?

[Richard_Z]

Hello,

I'm adding this unsubscribe button to my HTML page:

<a href="https://www.paypal.com/cgi-bin/webscr?cmd=_subscr-find&alias=mysandboxaccountid">
<img src="https://www.paypalobjects.com/en_US/i/btn/btn_unsubscribe_LG.gif" BORDER="0">
</a>

It's linking to the live Paypal site "https://www.paypal.com" so I cannot test with sandbox account.

I tried to replace the url with "https://www.sandbox.paypal.com" but it didn't work.

Is there any way I can test this in sandbox?

Best, Richard
