Splash Integration with Greenhouse: Event-to-ATS Sync and Best Practices

The Splash-to-Greenhouse integration streamlines event-sourced recruiting by automatically syncing registrant and attendee data from Splash into Greenhouse. That connection turns event contacts into tracked prospects or candidates inside your ATS so recruiting teams can measure event ROI and move qualified talent toward interviews without manual CSV imports. This article explains how the integration works, who benefits, key configuration and data-mapping details, measurable outcomes to monitor, and practical best practices for event-driven hiring pipelines.

At a high level, Splash captures registrations, check-ins, and attendee engagement metadata; the integration forwards that data to Greenhouse as prospects or candidate records, with event tags and source attribution preserved. Teams use the sync to convert attendance into pipeline activity, prioritize follow-up, and report on conversion metrics from registration to hire.

How the Splash → Greenhouse sync typically works

• Registration capture Attendees register in Splash using an event page or QR-code check-in; their submitted fields (name, email, role interest, resume attachments if provided) are stored as registrant records.
• Mapping and authentication An admin links Splash to Greenhouse using API credentials and configures field mappings (e.g., Splash 'Role Interest' → Greenhouse 'Prospect Custom Field').
• Automatic creation or update On registration or check-in, Splash pushes the record to Greenhouse: creating a prospect or updating an existing candidate by unique identifier (email).
• Event attribution The integration tags the Greenhouse record with event name, date, and source so downstream reporting shows hires sourced or influenced by events.
• Ongoing enrichment Attendance updates and session-level engagement (e.g., RSVPed vs. Attended) sync back to Greenhouse, allowing recruiters to prioritize attendees who engaged onsite.

Common fields synced from Splash to Greenhouse

Who needs this integration? Any talent acquisition team running in-person or virtual recruiting events benefits, especially campus teams, university relations, sourcing teams that run meetups/hackathons, and recruiting marketing teams tracking event ROI. It’s also valuable for hiring managers who want a dependable candidate feed from events directly into their ATS workflows.

High-value use cases

• Campus recruiting and info sessions Automatically create prospects for students who register and push top attendees into interview pipelines the week after events.
• Hackathons and technical events Capture role interest and code samples at registration; tag candidates by skill and fast-track follow-up for high-performers.
• Employer brand activations Measure how many brand-driven events actually create candidate pipeline versus just marketing impressions.
• Regional hiring events Aggregate attendees across multiple events into Greenhouse with consistent event tagging to compare performance by city or event type.

Implementation considerations that reduce friction include deciding whether registrants should create prospects or full candidate records, configuring deduplication rules (email is the common unique key), and deciding sync cadence (real-time on registration vs. batch post-event). Confirm API permission scopes in Greenhouse and test mappings with a staging event before rolling out.

Event-to-ATS metrics to track post-integration

• Registrations → Applications Percentage of registrants who submit a formal application in Greenhouse.
• Attendance → Interview conversion Share of attendees who reach interview stages.
• Time-to-first-contact Average time from attendee check-in to recruiter outreach.
• Cost-per-hire from events Event spend divided by hires attributed to that event source.

Common questions about the integration

Best practices for event-driven recruiting workflows: add a standard event tag prefix so all event-sourced records are filterable, capture at-registration screening questions to pre-qualify candidates, set an automation in Greenhouse to assign event leads to sourcers within 24–48 hours, and run a weekly report that ties event sources to stage conversions.

ROI indicators and how to measure them

Pre-launch checklist for a smooth rollout

• Define mapping and unique keys Decide which Splash fields map to Greenhouse fields and which field (email) prevents duplicates.
• Set consent capture Add explicit consent checkbox on registration forms and store the timestamp and opt-in field.
• Test with a pilot event Run a small internal event to validate sync behavior, attachments, and tag propagation.
• Establish follow-up SLAs Set recruiter ownership rules and SLAs for time-to-first-contact after attendance is recorded.
• Enable reporting Create Greenhouse reports and dashboards that filter by event tags and source for weekly review.

Security and operational notes: use scoped API keys, restrict access to event-to-ATS mappings, and maintain an audit trail of records created by the integration. Periodically review retention of event-derived prospects to avoid stale pipelines and comply with data retention policies.

Troubleshooting tips

Integrating Splash with Greenhouse turns events into measurable pipeline channels. To get the full benefit, automate the flow from registration to qualification to outreach, and measure conversion at each step so you can invest in events that actually produce hires.
