Hi, we managed to complete the credit card payment via PayPal SDK on PayPal Sandbox environment, but once we've switched it to PayPal Live environment, the payment could not get thru, we're receiving HTTP response Unauthorised (401) code from PayPal Live env. We've confirmed that our PayPal Live API credentials (clientId and secret) are being applied, and the mode has been set to "live" as well. May I know what could be the other possibilities of getting (401) code? <settings> <add name="mode" value="live"/> <add name="connectionTimeout" value="360000"/> <add name="requestRetries" value="1"/> <add name="clientId" value="[our live credentials]"/> <add name="clientSecret" value="[out live credentials]"/> </settings>
