Validated assessments via Lever's webhook + feedback form pattern.
Lever does not have a dedicated Assessment Partner API. JobCannon's integration uses Lever webhooks + Feedback Forms API to deliver scores into the candidate profile. On the Phase 1 roadmap (target H2 2026).
In brief
Unlike Greenhouse, Ashby, and Workable, Lever does not expose a dedicated Assessment Partner API. The integration pattern is different: JobCannon listens for Lever webhook events (candidateStageChange, applicationCreated), triggers an assessment via email when a configured stage is reached, and returns the score by writing to Lever's Feedback Forms API. The candidate result envelope is preserved on the candidate profile as a structured feedback form. This is on the Phase 1 roadmap (target H2 2026); architectural complexity is the reason for the later ship date relative to Greenhouse + Ashby + Workable.
What the Lever integration enables
Webhook-driven trigger
Lever webhooks fire on candidate stage change. JobCannon listens for configured stages and auto-triggers an assessment invitation.
Feedback Form result delivery
JobCannon writes the result envelope to Lever's Feedback Forms API as a structured form on the candidate profile. Recruiters see the assessment score inline with their interview feedback.
Same 22-test catalog
Big Five, DISC, EQ, IQ, integrity, conflict styles, values, leadership style, work style. Identical to Greenhouse, Ashby and Workable integrations.
No code change for downstream
JobCannon abstracts Lever's pattern behind the same provider interface as Greenhouse + Ashby + Workable. Your scorecard automation works regardless of which ATS the candidate came from.
How it works
From Lever admin to first scored candidate.
- 1
JobCannon registered as Lever app
Lever's partner programme requires app registration; JobCannon's registration is on the Phase 1 roadmap.
- 2
Customer authorises JobCannon
Lever admin authorises JobCannon via OAuth. JobCannon subscribes to candidateStageChange webhooks.
- 3
Configure trigger stages
In JobCannon admin, customer selects which Lever stages should auto-trigger an assessment (e.g., "Phone Screen" → Big Five + EQ).
- 4
Stage change → assessment
When a candidate enters a trigger stage, Lever webhooks JobCannon; JobCannon emails the candidate.
- 5
Score → Feedback Form
On completion, JobCannon writes the result envelope to Lever's Feedback Forms API. Score visible on candidate profile alongside interview feedback.
22 hire-eligible assessments available via Lever
Same catalog across all JobCannon ATS integrations. Clinical and esoteric tests excluded by design.
Why teams pick JobCannon for Lever
- 56 hire-relevant assessments — Big Five, DISC, EQ, IQ, integrity, cognitive ability, conflict styles — validated against published psychometric standards, not vendor-curated.
- Multi-tenant org isolation by design — each customer's candidates are isolated at the row level (RLS), so the same adapter serves Greenhouse, Ashby, Lever and Workable from one codebase.
- Sub-1s scoring + standardised result envelope — every assessment returns the same shape (dimensions[].score) so your ATS can rank candidates without provider-specific glue.
- Sandbox + production environments — credentials with `is_sandbox` flag let your team run end-to-end test cycles without polluting hire pipelines.
- EU-resident data + GDPR-ready DPA — assessments and PII stay on EU Supabase, retention defaults to 90 days with org-level override.
56 validated assessments, multi-tenant org isolation, sandbox + production environments, sub-1s scoring, REST + webhook delivery. Free for sandbox + first 5 invitations/mo. From $99/mo on the Business tier; partnership engagements scope white-label and higher rate limits.
Frequently asked
Why is Lever later than Greenhouse, Ashby, and Workable?+
Architectural reason: Lever has no dedicated Assessment Partner API. The integration uses webhooks + Feedback Forms, which requires a different state machine and a different result-delivery pattern. We chose to ship the three Assessment-API-native ATSes first (faster, lower risk), then circle back to Lever in H2 2026.
Will the result still appear on the Lever candidate scorecard?+
Yes — via Lever's Feedback Forms API. JobCannon writes a structured feedback form (one form per assessment) to the candidate profile. Recruiters see the score inline with interview feedback. Functionally equivalent to Greenhouse's scorecard integration; mechanically different.
Same 22-test catalog?+
Yes. The 22-test hire-eligible catalog (Big Five, DISC, EQ, IQ, integrity, conflict styles, etc.) is identical across Greenhouse, Ashby, Workable, and Lever integrations. Same envelope, same scoring, same multi-tenant isolation.
Does this work with Lever Hire and Lever Nurture?+
JobCannon integrates with Lever Hire (the ATS). Lever Nurture (CRM) is a separate product; assessments fire on application stage change, not on nurture campaign send.
How do I express interest?+
Email [email protected]. We'll add you to the early-access list and notify when JobCannon is registered as a Lever app and beta credentials are available.
Can I bridge in the meantime via the JobCannon REST API?+
Yes. The JobCannon Assessment API ($99/mo Business tier) accepts arbitrary external IDs; you can build a thin Lever→JobCannon bridge in your own infrastructure that listens to your Lever webhooks and POSTs to JobCannon. We provide reference code on request.
