I have WHMCS set up on my server, the problem is that for the invoicing system I prefer to have my own software on my desktop.
I have an accounting software called NCH express account, unfortunately their support is not helping that much for this problem.
The software ask for a gateurl which apparently should be this:
I have all of them.
Now when I enter these details in my accounting software It says that thegateway is not configured properly.
Now the reason I am adding this threa in the forum is not for the accounting software troubleshooting but the actual understanding of their PAYPAL API.
If I understand the things correctly, by setting up the Paypal API in both the WHMCS panel and my accounting software, invoices should be generated at the same time in both software.
Could it be that my local router is blocking the API post back from Paypal???
Any idea please?
