Why teams connect Apollo.io and Paylocity

Keep the people who own accounts in Apollo.io in step with the workforce records in Paylocity, so ownership, roles, and org structure stay current in both systems, in real time and in both directions.

Apollo.io runs on people as much as on accounts: every contact, deal, and account has an owner, and those owners are employees whose roles, teams, and status are held in Paylocity. Paylocity is the system of record for the workforce, from new hires to promotions to departures, and often for the candidates the business is still deciding on. When the two systems are connected only by re-keying or an overnight export, they drift apart, and the CRM ends up assigning accounts to people who have left, holding territories that no longer match the org chart, and waiting days to give a new rep access.

Stacksync syncs Tasks and calls, Custom fields, Contacts, Accounts in Apollo.io with Custom Fields, Employees, Onboarding, Deductions (Pay Setup) in Paylocity field by field, in real time, and in both directions. You decide which system owns which fields, so Paylocity stays authoritative on roles and org structure while Apollo.io keeps ownership and territory current, and Stacksync resolves conflicts by the rules you set.

Common use cases

  • 01 Land sequence enrollment status and outcomes in a warehouse for outbound performance reporting.
  • 02 Deduplicate contacts across Apollo and the CRM by syncing on email as the match key.
  • 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

New team members provisioned when they are hired

When Paylocity records a new hire, a matching user or owner is created in Apollo.io, so a new rep can start working accounts without waiting on a manual setup ticket.

Ownership and territory follow the org chart

When a person changes team, manager, or region in Paylocity, their accounts and territory assignments in Apollo.io update to match, so pipeline stays with the right owner.

Deactivate access when someone leaves

When Paylocity marks a worker as departed, the matching user in Apollo.io is flagged or deactivated, so former employees do not keep CRM access after their last day.

What you can sync between Apollo.io and Paylocity

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.

Apollo.io objects Paylocity objects How this pairing syncs
Custom fields Account- and contact-level custom attributes mapped field-by-field in a sync. Custom Fields Read-only company-specific custom fields returned by category, used to enrich the employee record downstream. Same entity on both sides — records pair one-to-one and field-level changes reconcile in both directions. Custom fields on either side are included in the mapping.
People (database records) Prospects from Apollo's global database, pulled into downstream systems once enriched or saved. Local and State Taxes Two-way via Create/Update/Delete Local Tax and Upsert Primary / Non-Primary State Tax; Get by tax code and Get All for reads. People (database records) is specific to Apollo.io and Local and State Taxes to Paylocity — each maps to any object or custom field on the other side.
Sequences Outreach cadences (emailer campaigns in the API); enrollment status is read to track which contacts are being worked. Direct Deposit Read-only: Get All Direct Deposit and Get Employee Bank Accounts return main and additional allocations. Bank details cannot be written through the API. Sequences is specific to Apollo.io and Direct Deposit to Paylocity — each maps to any object or custom field on the other side.
Deals (Opportunities) Pipeline records that can be read and written to keep Apollo aligned with the CRM of record. Pay Statements Read-only detailed payroll statement data — earnings, deductions, taxes, and direct deposit allocations by year, check date, or date range. Pulled for reporting, never written. Deals (Opportunities) is specific to Apollo.io and Pay Statements to Paylocity — each maps to any object or custom field on the other side.
Tasks and calls Rep activity records synced for activity reporting and coaching workflows. Company Codes Read-only reference codes and descriptions (cost centers, departments, positions) used to validate field mappings on employee writes. Tasks and calls is specific to Apollo.io and Company Codes to Paylocity — each maps to any object or custom field on the other side.
Contacts People saved to your Apollo account, synced with emails, phone numbers, and enrichment fields. Employees Core HR record keyed by companyId + employeeId; two-way via Create New Employee (POST) and Update Employee (PATCH), plus Get Employee / Get All Employees for reads. Contacts is specific to Apollo.io and Employees to Paylocity — each maps to any object or custom field on the other side.

How changes propagate between Apollo.io and Paylocity

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.

Apollo.io Paylocity Interval-based propagation

DetectionStacksync polls Apollo.io for changes on an incremental schedule, reading only records changed since the previous pass. Polling on updated-at timestamps.

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

Paylocity Apollo.io 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 Apollo.io through its API, with automatic retries and rate-limit backoff.

Rate-limit considerations

  • Apollo.io: Rate limits and enrichment credits vary by plan; bulk endpoints are throttled separately from single-record calls.
  • Paylocity: 25 requests per second (1,500 per minute); exceeding it returns HTTP 429. Every path is scoped to a Paylocity-assigned companyId (a company code, not a UUID).

Apollo.io

API key (passed in request headers); master keys unlock account-wide endpoints
Change detection
Polling on updated-at timestamps; webhook callbacks exist only for delivering asynchronous enrichment results, not as a general change-event stream

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.
