Why teams connect Paylocity and Resend

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

Each tool in Resend 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. Paylocity 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 Broadcasts, Domains, Email events, API keys in Resend with Deductions (Pay Setup), Earnings (Pay Setup), Local and State Taxes, Direct Deposit in Paylocity bi-directionally and in real time. A person added, moved, or offboarded in Paylocity creates or updates the matching user in Resend within seconds, with field-level mapping and conflict resolution in place of spreadsheets and one-off account changes. Where Resend captures details of its own, such as a corrected contact or a login identity, those can flow back to Paylocity 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 Trigger transactional sends when a row changes in an operational database, such as an order status update.
  • 02 Keep suppression and unsubscribe state synced between Resend and other marketing tools to stay compliant.
  • 03 Push hired candidates from an ATS into Paylocity via the Onboarding endpoint, then read Onboarding Status to confirm the record before the first payroll run.
  • 04 Upsert recurring Deductions and Earnings on employee records when benefits or 401(k) elections change in a benefits admin system, without re-keying payroll setup.

Common sync patterns

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

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

Onboarding: access ready on day one

A new hire recorded in Paylocity creates the matching user in Resend 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 Paylocity, the matching account in Resend is deactivated or flagged, so departures do not leave open access behind.

How changes propagate between Paylocity and Resend

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.

Paylocity Resend Sub-second propagation

DetectionPaylocity notifies Stacksync of record changes through webhook events. Webhooks — Paylocity POSTs Employee New Hire, Employee Change, Termination, Payroll Processed, and Time Off Approval events to a callback URL.

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

Resend Paylocity Sub-second propagation

DetectionResend notifies Stacksync of record changes through webhook events. Webhooks for email lifecycle events.

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

Rate-limit considerations

How the Paylocity and Resend connectors work

Paylocity

Integration surface
REST API (v1 and v2), JSON payloads
Authentication
OAuth 2.0 client credentials via the Paylocity Identity Provider (/IdentityServer/connect/token) with the WebLinkAPI scope; access tokens expire after one hour and API access must be enabled by Paylocity for the company
Change detection
Webhooks — Paylocity POSTs Employee New Hire, Employee Change, Termination, Payroll Processed, and Time Off Approval events to a callback URL; payloads carry only companyId and employeeId, so the receiver calls the relevant API to fetch changed values. Scheduled polling is used for objects without webhooks.
