 * Hi [@omarhamsho](https://wordpress.org/support/users/omarhamsho/),
 * Anytime you receive a client authentication error it means the secret key is 
   incorrect.
 * If you go to WooCommerce > Status > Logs you will find a `wc-ppcp` log file. 
   That file will have a entries for the failed API requests to PayPal along with
   additional information.
 * Since it sounds like you manually entered the API keys info, you will want to
   re-enter the secret key value.
 * Kind Regards

 * Same issue here. I connected to Paypal by wizard and the status is connected.
   But it’s impossible to create Webhook and make any online transition: Client 
   Authentication failed.
 * Any suggestion? I tried to re-connect again but same result. Should it be better
   to get Production Client ID and Production Client ID manullay out of Paypal account?
 * Thanks.

 * Go to the WooCommerce > Status > Logs page and check the `wc-ppcp` log file. 
   What does the log say about the failed requests to PayPal?
 * > Should it be better to get Production Client ID and Production Client ID manullay
   > out of Paypal account?
 * That is an option if you’re having trouble with the Connect process. Here is 
   the step by step instructions from our documentation. [https://docs.paymentplugins.com/wc-paypal/config/#/connect?id=manually-connect](https://docs.paymentplugins.com/wc-paypal/config/#/connect?id=manually-connect)

 * It’s quite difficult to check if the Paypal account is correctly set, when your
   client manages it and you don’t have access to it.
 * This is the [log file](http://stage.chconte.eu/PROVA/log-error.txt), if you please.
   Thanks again.
