We have a server that is running a REST API on port 443. I'd like to make sure it's secure by doing various pen tests on it. I'm used to doing offensive testing on a webpage where I can see code, and URLs, and find forms to test. But I'm completely blind when testing an API. I don't even know what are valid URLs to test against. Is there any good documentation on how to do this, perhaps using Kali Linux?

    Astra is one which I came across: > Astra can be used by security engineers or developers as an integral > part of their process, so they can detect and patch vulnerabilities > early during development cycle.

REST Security and API Security are excellent topics of research.

This question and the answers provide good starting points to find great tools and techniques to test these interfaces -- API Security Testing Methodologies

If I were you, I'd avoid testing a REST interface or an API's security remotely, or via a black-box technique such as dynamic app security testing. What you want is to analyze the design decisions (this blog post is a great reference with .NET code examples and component recommendations) and/or perform a secure code review. One tool that I commonly use to perform secure code reviews is Find Security Bugs. For analyzing components, there is OWASP Dependency Check (with multiple language support), bundler-audit for Ruby, Retire.js (or Snyk.io) for JavaScript, and OWASP SafeNuGet for .NET projects.
