Connect Lever and Slack to Automate Your Hiring Workflow
Keep your recruiting team in sync by sending candidate activity from Lever straight into Slack.
Lever + Slack integration
Lever is a leading applicant tracking system (ATS) that helps talent teams manage candidates, pipeline stages, and hiring decisions at scale. Slack is where modern teams communicate and move fast. Together, they give your recruiting operation a real backbone — every application, interview, and offer update lands in front of the right people instantly, no manual dashboard checks required.
Recruiting moves fast, and a missed update can mean a lost candidate or a delayed hire. When Lever and Slack are connected, hiring managers get instant notifications when a candidate advances through the pipeline, interviewers get reminders before scheduled sessions, and the whole team can celebrate offer acceptances the moment they happen. Manual status updates disappear. Communication gaps between recruiters and hiring managers shrink. And everyone stays current on headcount progress without leaving Slack.
Automate & integrate Lever + Slack
Automating Lever and Slack business processes or integrating data is made easy with Tray.ai.
Use case
Real-Time Candidate Stage Notifications
When a candidate moves to a new stage in Lever — Phone Screen, Onsite, Offer — a Slack message goes automatically to the relevant hiring channel or hiring manager's DM. Stakeholders always know where the pipeline stands without logging into Lever. Recruiters spend less time writing status updates and more time talking to candidates.
- Eliminate manual status update messages between recruiters and hiring managers
- Cut response lag when candidates are ready for next-stage scheduling
- Keep hiring teams informed without adding to their dashboard workload
Use case
New Application Alerts for High-Priority Roles
When a new application comes in for a high-priority or hard-to-fill role, an automatic Slack alert goes to the recruiting lead or hiring manager right away. The team can review and respond to strong candidates before those candidates lose interest. Priority roles get fast attention without anyone needing to watch Lever all day.
- Speed up time-to-review for critical open positions
- Make sure high-value applicants don't get buried in a crowded inbox
- Let hiring managers act on top candidates within hours, not days
Use case
Interview Scheduling Reminders and Confirmations
Once an interview is scheduled in Lever, interviewers automatically get a Slack reminder with candidate details, the interview format, and any prep notes. A follow-up reminder can fire 24 hours and again 1 hour before the interview. No-shows drop, interviewers show up prepared, and recruiting coordinators stop sending manual calendar follow-ups.
- Reduce interview no-shows and last-minute reschedule requests
- Give interviewers candidate context before they walk into a session
- Cut manual reminder emails from recruiting coordinators
Use case
Offer Acceptance Announcements
When a candidate's status flips to Offer Accepted in Lever, a celebratory Slack message posts automatically to a company-wide or team-specific channel. Leadership gets visibility into hiring momentum, the broader team gets to share the moment, and downstream workflows — notifying IT or HR to start onboarding prep — kick off automatically.
- Build company culture by celebrating new hires as they happen
- Give leadership and team leads immediate visibility into headcount wins
- Trigger onboarding prep workflows the moment an offer is accepted
Use case
Candidate Rejection Notifications to Hiring Managers
When a candidate is archived or moved to a rejected stage in Lever, a private Slack notification goes to the hiring manager with a summary of the decision and reason. No separate email thread, no Lever login required. Hiring managers stay in the loop and can share feedback directly in Slack.
- Close the loop on candidate decisions without extra email threads
- Give hiring managers a clear picture of pipeline health in Slack
- Enable quick feedback loops that improve future sourcing
Use case
Weekly Recruiting Pipeline Digest
A scheduled automation pulls pipeline metrics from Lever each week — new applications, interviews completed, offers extended, open roles — and posts a formatted summary to a designated Slack channel. Leadership and hiring managers get a consistent view of recruiting health without generating reports by hand. Ad hoc status meetings become optional.
- Replace manual recruiting status reports with automated weekly digests
- Give leadership a consistent, reliable view of hiring pipeline health
- Cut time spent in recurring recruiting update meetings
Challenges Tray.ai solves
Common obstacles when integrating Lever and Slack — and how Tray.ai handles them.
Challenge
Mapping Lever Webhook Events to the Right Slack Recipients
Lever fires webhook events for a wide range of candidate actions, but routing each notification to the right Slack user or channel means matching recruiters, hiring managers, and interviewers across both platforms. Without a reliable mapping layer, notifications go to the wrong person or get broadcast too broadly.
How Tray.ai helps
Tray.ai's workflow builder has conditional logic and data transformation tools that map Lever user IDs to Slack user IDs dynamically, route messages by job department or team, and let you set role-specific notification rules — no custom code needed.
Challenge
Avoiding Notification Fatigue in High-Volume Pipelines
Organizations with large recruiting pipelines can generate dozens of Lever stage changes per day. Without filtering, Slack channels fill up fast with notifications that hiring managers start ignoring — which defeats the whole point.
How Tray.ai helps
Tray.ai lets you build smart filtering logic into each workflow — only notifying for specific stages, roles above a certain seniority level, or requisitions tagged as urgent — so Slack messages stay relevant, actionable, and actually worth reading.
Challenge
Handling Lever API Rate Limits in Scheduled Digest Workflows
When pulling aggregate pipeline data from Lever for weekly summaries, workflows that make multiple sequential API calls can hit Lever's rate limits, causing incomplete or failed report deliveries.
How Tray.ai helps
Tray.ai has built-in rate limit handling, automatic retries with exponential backoff, and efficient API request batching. Your scheduled digest workflows complete reliably and deliver accurate data to Slack every time.
Automatically posts a Slack message to a specified channel or DM whenever a candidate in Lever moves to a new pipeline stage, including candidate name, role, and stage details.
Watches for new applications on tagged high-priority requisitions in Lever and immediately sends a Slack alert to the recruiting lead with applicant details and a direct link to the Lever profile.
Sends automated Slack reminders to interviewers 24 hours and 1 hour before a scheduled interview, pulling candidate and role details directly from Lever.
When a candidate's Lever status is updated to Offer Accepted, this template automatically posts a congratulatory message to a team or company-wide Slack channel with the new hire's name and role.
Runs on a weekly schedule to query Lever for recruiting metrics and posts a structured pipeline digest — open roles, new applicants, interviews, and offers — to a leadership Slack channel.
