Hi @saadezz,
Greetings from WebToffee support. The error message usually occurs due to the wrong PayPal API credentials.
To get the Client ID and Secret for the Smart buttons:
- Login to your PayPal business account .
- Scroll down to the REST API Integration section and click Manage API apps and credentials . The REST API apps window opens up.
- Go to Activity > API Access OR from Account Settings > API Access.
- Click on the PayPal Developer experience link to create or manage apps.
- Next, Login to developer account or Signup a new developer account. Click on the Create a new application or default application for your business account. Then, copy the Client ID and Secret.
- Paste the Client ID and Secret in the respective fields of the plugin.
Let us know how it goes.
