How Can I Integrate Zendesk APIs with Custom Automation Tools for Streamlined Operations?

Hello, Zendesk Community,

I'm integrating Zendesk APIs with a custom automation tool and am encountering a few problems. I'd like to be able to auto-update tickets as well as customer notifications using the external tool. Here are the questions I encounter:

How would you integrate third-party automation tools into Zendesk's APIs without hitting performance?
How do you go about using Zendesk's APIs with the custom macros or scripts?
Are there some known limitations about combining Zendesk APIs with tools outside that might impact its performance?
Some insights or even experiences would be appreciated on this. Want to make things work better from the integration to ensure everything else goes smoothly.

Thanks in advance!
