Greenhouse Job Board Change Tracker for n8n (Apify Snapshots)

Track Greenhouse job board changes automatically with Apify Snapshots (n8n)

This n8n workflow monitors up to 20 known Greenhouse company boards, captures validated Apify snapshots, and highlights what changed between runs—so your team can maintain accurate company job feeds without manual checks.

What this workflow does

• Starts from a Manual Trigger and loads your configured Greenhouse board slugs (1–20) along with the dedicated Apify key-value store name.
• Initializes and reads stored state by creating (or opening) the Apify key-value store and checking the STATE record to see whether a previous snapshot exists or a run is already pending.
• Prepares the Apify Actor run safely: if no run is pending, it builds the actor input (including the previous snapshot when available), writes a pending start intent to STATE, and verifies it was persisted correctly.
• Starts or resumes the Apify run without auto-polling. The status request waits up to 60 seconds; if still running, execution stops while preserving the run ID for later retrieval.
• Validates outputs from Apify (including SUMMARY, BILLING receipt, SNAPSHOT, and CHANGES.json) and confirms they match the requested board list and expected counts.
• Saves the next snapshot as “ready” state in the Apify key-value store (including the latest snapshot and last run ID), then outputs the run link, counts, and detected change list.

Use cases

• Maintain accurate “Jobs at Company X” pages by flagging Greenhouse listings that changed since the last snapshot.
• Build an n8n-driven pipeline that audits job board updates for 1–20 Greenhouse boards on demand.
• Support SaaS operations by tracking posting changes and surfacing diffs as a structured output.
