I am setting up Express Checkout, but these past 2 days I am receiving a Permission denied (403) error when I click the PayPal button. It is supposed to launch the pop-up window for logging in, however it auto-closes after a second, and it returns an error in the console saying:
Request to post https://www.sandbox.paypal.com/v1/payments/payment failed with 403 error.
"name": "PERMISSION_DENIED",
"message": "No permission for the requested operation"
A few days into the build, this was working, but now it is always that error. I created a PayPal REST API app here:
https://developer.paypal.com/developer/applications/create
... and I am using the Client IDs from the sandbox and from the live tab. If I switch the setting "env" to "production", I get the same error.
To make sure this is not an error in my code, I run the test here:
https://developer.paypal.com/demo/checkout/#/pattern/client
... by replacing the "sandbox" and "production" values with my own. But it is still the same, when I click on the button, it always returns the "permission denied" error, like there is something wrong with the account's permissions.
I spent a couple of days looking through the account settings, trying to find if something was wrong, or disabled, or if some info is missing, but I can't find the cause there. I have run out of options.
Can you please help me?
Thank you!
