Why teams connect Front and Lever

Keep the people, teams, and status that Front and Lever share aligned in real time, so a hire, role change, or departure recorded in one reaches the other within seconds.

Each tool in Front keeps its own list of who can use it: users, members, or agents, along with the team they sit on and whether they are still active. Lever is the authoritative record of the same people as employees, with their department, manager, and employment status. When those two are connected only by manual account admin or a periodic export, the work tools drift: new hires wait days for access, team and manager changes never catch up, and people who have left keep standing accounts.

Stacksync syncs Messages, Comments, Contacts, Accounts in Front with Opportunities, Postings, Requisitions, Offers in Lever bi-directionally and in real time. A person added, moved, or offboarded in Lever creates or updates the matching user in Front within seconds, with field-level mapping and conflict resolution in place of spreadsheets and one-off account changes. Where Front captures details of its own, such as a corrected contact or a login identity, those can flow back to Lever in whichever direction you configure.

Because the sync is field-level, each system keeps its own extras; only the shared facts, who a person is, which team they belong to, and whether their access should be on, are held in agreement.

Common use cases

  • 01 Write CRM account tier, owner, and renewal data into Front contact and account custom fields so it shows next to the conversation.
  • 02 Keep Front contacts and accounts aligned with CRM contacts and accounts in both directions.
  • 03 Consolidate Feedback, Interviews, and Notes into a warehouse for interviewer scorecard and time-to-fill reporting.
  • 04 Write enriched Sources, Tags, and Contact data back onto Opportunities from an outbound sourcing pipeline.

Common sync patterns

Where Front routes or assigns work by person: assignments follow the org

When someone changes teams or managers in Lever, the queues, ownership, or approvals in Front update to match, so work reaches whoever holds the role now.

Onboarding: access ready on day one

A new hire recorded in Lever creates the matching user in Front with the right team and manager already set, so people can start working without waiting on a provisioning ticket.

Offboarding: no standing access after a departure

When someone is marked as leaving in Lever, the matching account in Front is deactivated or flagged, so departures do not leave open access behind.

What you can sync between Front and Lever

Representative objects on each side — any object or custom field can map to any target. Schemas are auto-detected; types are converted between the two systems.

Front objects Lever objects How this pairing syncs
Tags Labels applied to conversations; drive routing and category-level analytics. Interviews Scheduled interview panel events with times and interviewers; read for scheduling reporting and time-to-hire metrics, and creatable via the panels endpoint. Tags is specific to Front and Interviews to Lever — each maps to any object or custom field on the other side.
Teammates Agents; used for ownership mapping and workload reporting. Notes and Contacts Free-text Notes on Opportunities plus the underlying Contact (person) that dedupes multiple Opportunities; notes are posted via POST /opportunities/:id/notes and contact-level tags, sources, and links can be added back for attribution. Teammates is specific to Front and Notes and Contacts to Lever — each maps to any object or custom field on the other side.
Channels Connected addresses (email, SMS, chat); define where messages originate and send from. Opportunities The core pipeline record for a candidate applying to a role; replaced the deprecated Candidates endpoint. Created via POST /opportunities and updated (stage, archive, links, tags, sources, files) through the API, and synced two-way with a database or HRIS. Channels is specific to Front and Opportunities to Lever — each maps to any object or custom field on the other side.
Conversations The central threaded unit that messages, comments, and tags attach to; synced for support analytics. Postings Job posting records with categories, apply URLs, workplace type, and requisition codes. Can be created via POST /postings and read into a warehouse for open-role reporting. Conversations is specific to Front and Postings to Lever — each maps to any object or custom field on the other side.
Messages Inbound and outbound emails, chats, and SMS within a conversation; read out for response-time reporting. Requisitions Headcount/requisition records with custom requisition fields, tied to Postings; read via GET /requisitions and synced to an HRIS to reconcile approved headcount against open roles. Messages is specific to Front and Requisitions to Lever — each maps to any object or custom field on the other side.
Comments Internal team notes on conversations; usually read-only in syncs. Offers Offer records attached to an Opportunity with status and offer-form fields; exposed read-only through GET /opportunities/:id/offers, so they sync outbound to an HRIS or onboarding system when a candidate reaches the offer stage. Comments is specific to Front and Offers to Lever — each maps to any object or custom field on the other side.

How changes propagate between Front and Lever

Each direction of the sync is driven by what the source system can signal and what the destination accepts — detection, delivery, and expected latency below.

Front Lever Sub-second propagation

DetectionFront notifies Stacksync of record changes through webhook events. Application webhooks and rule-triggered webhooks, with the events endpoint available for polling.

DeliveryEach detected change is written to Lever through its API, with automatic retries and rate-limit backoff.

Lever Front Sub-second propagation

DetectionLever notifies Stacksync of record changes through webhook events. Webhooks for candidate and application lifecycle events (applicationCreated, candidateStageChange, candidateArchiveStateChange, candidateHired,.

DeliveryEach detected change is written to Front through its API, with automatic retries and rate-limit backoff.

Rate-limit considerations

  • Front: Request limits vary by plan.
  • Lever: 10 requests/second per API key with a token-bucket burst to ~20/s; POSTs that create candidates/applications are throttled to roughly 2/second. Sustained overage returns 429 with Retry-After. List endpoints are cursor-paginated at up to 100 records per page.
