How to access REST APIs logs?

Summary:

3rd party trying to understand what is the issue with the data they are sending through REST APIs

Content (please ensure you mask any confidential information):

We have a vendor that has been sending time data through APIs for a while now.

But now it is asking me to check what is the error we are seeing on ORACLE when they send the data.

Is there any place where I can go and see what are the REST API logs with the errors?
