Hi,
It is indeed hardcoded in the plugin as the URL is normally not supposed to change and it should not be up to the user to change it. So you were right to contact us about it.
I'm assuming you're using the plugin sold on our marketplace by TsukiDev:
www.hikashop.com/marketplace/product/246-zip-pay-zip-money.html
I had a look at the code of the plugin (you can open the file plugins/hikashoppayment/zipmoney/zipmoney.php via FTP if you want to take a look).
There, I can see:
if($zipmoney_mode==1)
{
$api_url='https://api.sandbox.zipmoney.com.au/merchant/v1/checkouts';
}
else
{
$api_url='https://api.zipmoney.com.au/merchant/v1/checkouts';
}and:
if($_REQUEST['zipmoneymode']==1)
{
$api_url='https://api.sandbox.zipmoney.com.au/merchant/v1/charges';
}
else
{
$api_url='https://api.zipmoney.com.au/merchant/v1/charges';
}So, from what I understand of the link you provided the plugin you need to update these.
I'll be forwarding your message to TsukiDev so that they can look into it rapidly and publish a new version of the plugin with the changes integrated by default.
