I still can’t get this to work. I have deleted all “products” so all shortcodes are gone. Also deleted all webhooks. It is now fine to insert the Live Client ID and Live Secret key, as well as corresponding values for the Sandbox. The problem occurs when I create new PayPal webhooks under the “Subscription” tab.
Creating “Live Webhook Status” goes fine. Here I get a green tick. The issue is Test Webhook Status. Here it says “No webhook found. Use the following Create Webhook button to create a new webhook automatically in your PayPal account.”. When I click on the “Create webhooks” button, I get the following error message: “Webhook URL already exists: null”. Tried deleting the webhooks again, but still get the same result. What am I doing wrong? Have now almost spent 1 year trying to switch from one PayPal account to another.
