erro paypal adaptive payments

Hello-
Are you using live or sandbox?
This error indicates that you are using invalid Application ID. If you have set the configuration of the module to Production mode, you must use your own Application ID.

In live mode, but I was able to solve the problem, I found a tutorial on the site of you https://www.wcvendor.com, thank you for answering me and for the good service!

You’re welcome! Glad you were able to get it working properly.
