API / Venafi Interview questions

What is the difference between Venafi's REST API and its Adaptable connector framework?

Both let external systems interact with TPP, but they operate from opposite directions and serve different integration needs.

REST API (/vedsdk, /vedauth)	Adaptable connector framework
TPP is called by external tools	TPP calls out to external systems
Used by clients like VCert, Terraform, custom scripts	Used to connect TPP to a CA, application, or log destination that lacks a native plugin
Fixed, versioned, vendor-defined contract	Customer-authored scripting hooks (commonly PowerShell)
Good fit: requesting/retrieving certificates programmatically	Good fit: onboarding a niche or homegrown system into policy and orchestration

A useful way to keep them straight: the REST API is the door other tools use to ask TPP for something; the Adaptable framework is how TPP itself learns to talk to a new external system it doesn't natively support — they're solving integration in opposite directions.

Take quiz

Which direction does the Adaptable connector framework operate in? External tools calling into TPP

✗ Try again — that's the REST API's direction.

TPP calling out to an external system that lacks a native plugin

✓ Well done! Adaptable connectors extend TPP's outbound reach.

Neither; it doesn't involve any external communication

✗ Try again — it's specifically about integrating with external systems.

Which tool would you use to programmatically request a certificate from a CI/CD job? The REST API, via a client like VCert

✓ Well done! That's exactly what /vedauth and /vedsdk are built for.

An Adaptable connector

✗ Try again — Adaptable connectors are for TPP integrating with new external systems, not for a CI job requesting a cert.

Neither; certificates can only be requested through the web console

✗ Try again — the REST API supports fully programmatic requests.
