ATS
Native connectors need Growth+. Long-tail ATS use webhooks + the Public API.
Greenhouse
Harvest API — interview rooms + invite recipes
Lever
API key or OAuth — notes on opportunities
Ashby
API key or OAuth — application notes
Workday
Basic auth + RaaS — optional stage filter
BambooHR
API key + subdomain
Zoho Recruit
OAuth — stage filter; inbound needs Pro+
Breezy HR

Automations & agents
Automations overview
When to use Zapier, n8n, Make, or a custom worker
n8n
Verified community node
Zapier
Assess app — events, invites, pipelines
Make
Custom App — Watch Assess Event + modules
Build with agents
Knowledge MCP, API MCP, and hiring skills for Cursor / Claude / Codex
MCP / agents
Coding agents that call Assess API tools
Webhooks
HTTPS destinations, signatures, delivery logs
Two loops (do not mix them up)
Native connectors do not send assessment invites today. A Greenhouse stage change does not create a take-home link unless you add Zapier, n8n, or Make.
For engineers
Scope for status endpoints:organisation:read.
Open
connect_url in a browser as owner, admin, or developer — do not complete OAuth from a server alone.
