贝宝订阅按钮错误

Question

This is my markup

<form action="https://www.sandbox.paypal.com/cgi-bin/webscr" method="post">
<input type="hidden" name="cmd" value="_xclick-subscriptions"/>
<input type="hidden" name="business" value="shubhangi254@gmail.com"/>
<input type="hidden" name="lc" value="US"/>
<input type="hidden" name="item_name" value="XYZ"/>
<input type="hidden" name="no_note" value="1"/>
<input type="hidden" name="src" value="1"/>
<input type="hidden" name="srt" value="3"/>
<input type="hidden" name="a3" value="10.00"/>
<input type="hidden" name="p3" value="1"/>
<input type="hidden" name="t3" value="M"/>
<input type="hidden" name="currency_code" value="USD"/>
<input type="hidden" name="bn" value="PP-SubscriptionsBF:btn_subscribeCC_LG.gif:NonHostedGuest"/>
<input type="image" src="https://www.paypalobjects.com/en_US/i/btn/btn_subscribeCC_LG.gif" border="0" name="submit" alt="PayPal - The safer, easier way to pay online!"/>
<img alt="" border="0" src="https://www.paypalobjects.com/en_US/i/scr/pixel.gif" width="1" height="1"/>
</form>

With this it redirects to paypal, but when I login with sandbox test account email it gives following error: The link you have used to enter the PayPal system is invalid. Please review the link and try again. The link you have used to enter the PayPal system is invalid. Please review the link and try again.

Any idea?

Answer 1

shubhangi254@gmail.com is not a Sandbox account. It's a developer account used for accessing https://developer.paypal.com/
You must also create a test buyer/seller account via https://developer.paypal.com/ > Test Accounts.
The value of 'business' will be the 'email address' of the Seller test account.
