How to Migrate HR Automation from Zapier to Make.com: A Step-by-Step Guide

Migrating HR automation from Zapier to Make.com™ is not a copy-paste exercise — it is a structured engineering project that, done correctly, leaves your hiring and onboarding workflows faster, more resilient, and cheaper to operate. Done incorrectly, it drops candidates through the cracks mid-hire. This guide gives you the exact sequence we use to move HR automation stacks off Zapier without disrupting live recruiting or onboarding operations. For the broader question of which platform architecture fits your compliance and data requirements, start with our parent guide on choosing the right HR automation platform architecture. If you want context on why legacy tools hit a ceiling, the strategic case for moving beyond legacy automation tools is worth reading first.

Before You Start: Prerequisites, Time, and Risk

This migration requires full access to your Zapier account, admin credentials for every connected HR application, and a Make.com™ account on a paid plan. Do not start on a free tier — execution log access is essential for testing and is not available on the free plan.

• Time commitment: Four to eight weeks for environments with 20–50 active Zaps. Larger stacks scale proportionally.
• Who needs to be involved: Whoever owns each connected HR system (ATS admin, HRIS admin, IT) must be available to issue API credentials during Step 3. Do not start without them confirmed.
• Primary risk: Deactivating Zaps before Make.com™ scenarios are confirmed stable. The mitigation is mandatory parallel operation — covered in Step 4.
• Secondary risk: Incomplete documentation in the audit phase. Any Zap you miss in Step 1 becomes an invisible gap in production.
• Tools required: Spreadsheet (Google Sheets or equivalent), Make.com™ paid account, admin access to all integrated HR platforms, and access to Zapier’s Zap history and task logs for each workflow.

Gartner research identifies integration and data migration failures as the leading cause of HR technology project overruns. The steps below are sequenced specifically to prevent that failure mode.

Step 1 — Audit Every Active Zap Before Touching Make.com™

Complete your Zapier inventory first. Do not open Make.com™ until this step is finished.

Open your Zapier dashboard and export a full list of every active Zap. For each one, document the following in a spreadsheet:

• Trigger: What event fires the Zap, and in which app.
• Actions: Every downstream step, in sequence.
• Connected apps: Every platform the Zap touches (ATS, HRIS, email, Slack, Google Workspace, etc.).
• Data fields mapped: Exactly which fields move between which systems.
• HR process it supports: Candidate screening, interview scheduling, offer letter delivery, onboarding task creation, payroll data entry, or other.
• Task volume: Pull 30-day task history to quantify how frequently each Zap fires.
• Owner: Who in the organization depends on this Zap and would notice if it broke.

Once the list is complete, review each Zap for one of three statuses: Migrate (active, needed), Retire (no longer relevant or broken), or Redesign (active but patching a process that should be rebuilt). In our experience, 20–30% of Zaps in a typical HR stack fall into Retire or Redesign — eliminating them before migration begins reduces build scope significantly.

Asana’s Anatomy of Work research found that workers spend a significant portion of their week on work about work rather than skilled work. Undocumented automations that nobody can explain are a direct contributor — they consume operations budget without anyone being able to account for the output.

Step 2 — Map Zapier Logic to Make.com™ Scenario Architecture

With your audit complete, translate each Zap’s logic into a Make.com™ scenario design — on paper, before building anything.

Make.com™ uses a different structural vocabulary than Zapier, and conflating the two during the build phase causes errors. Here is the translation map:

For each Zap marked for migration, sketch the Make.com™ scenario structure: which module fires first, how data passes between modules, where routers are needed, and where error handlers should attach. For designing resilient HR workflows with strategic error handling, plan error routes at this stage — not after the build is complete.

Flag any Zap that uses a custom webhook or an app without a native Make.com™ module. Those require an HTTP module build and need additional design time.

Step 3 — Recreate All API Connections and Authentications in Make.com™

Before building a single scenario, establish every API connection Make.com™ will need. Connection failures mid-build are the primary cause of stalled migration projects.

Work through your connected-app list from the audit and complete the following for each platform:

1. Navigate to Connections inside Make.com™.
2. Search for the native module for each app (ATS, HRIS, communication platform, Google Workspace, etc.).
3. Create the connection using the correct authentication method — OAuth2, API key, or service account credentials as required by that platform.
4. For platforms without a native Make.com™ module, note the API documentation URL and plan an HTTP module connection.
5. Test each connection individually using Make.com™’s built-in connection test before proceeding.
6. Where possible, create dedicated service accounts for Make.com™ integrations rather than connecting under personal user credentials — this ensures the integration survives staff turnover.

Do not begin Step 4 until every connection on your list shows a confirmed green status in Make.com™. A failed connection discovered mid-scenario build requires you to pause, fix credentials, and retest — breaking your build momentum and potentially corrupting in-progress data mapping.

Parseur’s research on manual data entry costs puts the per-employee cost of error-prone data handling at $28,500 per year. Connection errors that cause silent data failures — where a Zap appears to run but Make.com™ never receives the trigger — are the digital equivalent of that manual error cost.

Step 4 — Build Make.com™ Scenarios and Run Parallel Testing

Build in complexity order: simplest automations first, most complex last. Do not deactivate any Zap during this step.

Build Sequence

1. Start with single-action, single-trigger scenarios. These are your lowest-risk builds and the fastest to validate. Examples: new applicant in ATS triggers a Slack notification, or a completed onboarding form triggers a task creation in your project tool.
2. Build multi-step linear scenarios next. These have more modules but no branching logic. Map data fields precisely — Make.com™’s field mapping is more granular than Zapier’s, which means more control but also more surface area for mapping errors.
3. Build routed (branched) scenarios last. These are your former multi-branch Zaps. Build each router path independently, test each path with targeted data, then test the full scenario end-to-end.

Testing Protocol

For each scenario built, run the following test sequence before enabling parallel operation:

• Happy-path test: Run the scenario with a clean, complete input that should produce the expected output.
• Edge-case tests: Run with incomplete data, unexpected field values, and volume spikes to confirm error handlers fire correctly rather than failing silently.
• Output parity check: Compare Make.com™ output against Zapier output for identical inputs. Fields, formats, and downstream system records must match exactly.

Once a scenario passes the test sequence, enable it in Make.com™ while leaving the corresponding Zap active. Both run simultaneously. This parallel window must run for a minimum of two full weeks — long enough to cover a complete recruiting cycle and at least one pay period boundary.

During the parallel window, monitor Make.com™’s incomplete execution log daily. Any scenario that produces incomplete runs needs investigation before the corresponding Zap is retired. For a deeper look at the advanced HR automation capabilities unavailable in legacy platforms, Make.com™’s error-handler architecture is one of the most significant structural differences from Zapier.

Step 5 — Execute Phased Cutover and Retire Zaps

Phased deactivation — workflow-by-workflow, not all-at-once — limits your blast radius if an edge case surfaces post-launch.

Cutover Protocol

1. Choose a low-volume window. Schedule each Zap deactivation for a weekend or end-of-period window when triggering event volume is lowest. Avoid deactivating Zaps mid-week during peak recruiting activity.
2. Confirm in-flight tasks are complete. Any Zapier task that has been triggered but not yet fully processed will complete in Zapier even after the Zap is deactivated. Wait 24 hours after deactivating a Zap before assuming all in-flight tasks have resolved.
3. Deactivate the Zap — do not delete it yet. Deactivated Zaps retain their configuration and task history. Keep them deactivated (not deleted) for 30 days post-cutover as a reference and emergency fallback.
4. Monitor the Make.com™ scenario for 48 hours post-deactivation. Watch execution logs for volume anomalies, error rates, or incomplete executions that were masked during parallel operation.
5. Proceed to the next workflow only after 48-hour confirmation. Do not deactivate multiple Zaps simultaneously — sequence them so each deactivation is independently monitored.

Final Cleanup

After all scenarios have been running solo for 30 days without incident, delete retired Zaps, downgrade or cancel the Zapier subscription, and document the final Make.com™ scenario inventory as your new operational baseline. Update your runbook with Make.com™ scenario IDs, module descriptions, and owner assignments.

How to Know the Migration Worked

A successful migration meets all of the following criteria within 30 days of final Zap deactivation:

• Zero data gaps: No HR process owner has reported a missed trigger, incorrect data write, or failed notification that was previously handled by a Zap.
• Execution log clean rate above 95%: Make.com™ incomplete execution rate should be below 5% for all scenarios. Higher rates indicate unresolved edge cases.
• Error-handler activation under baseline: Error handler routes should be activating at or below the error rates you saw in Zapier task history. If Make.com™ is surfacing more errors than Zapier did, the errors existed before — Make.com™ is simply making them visible for the first time.
• Downstream system records match: Spot-check ATS, HRIS, and communication platform records weekly for the first month to confirm data written by Make.com™ matches the expected format and values.
• Process owners can’t tell the difference: The strongest success signal is that the HR team notices no disruption to their workflows — automation is invisible when it works correctly.

Common Mistakes and Troubleshooting

Mistake 1 — Rebuilding Instead of Redesigning

Replicating a broken process in Make.com™ produces a better-engineered broken process. Use the audit in Step 1 to question whether each workflow should exist at all before rebuilding it.

Mistake 2 — Skipping the Parallel Window

Teams that deactivate Zaps immediately after a successful happy-path test discover edge-case failures in production — when real candidates or new hires are affected. Two weeks of parallel operation is not negotiable.

Mistake 3 — Connecting Under Personal Credentials

When the employee who created the API connection leaves, the integration breaks. Service accounts prevent this. Create them before the migration begins, not as a post-launch cleanup task.

Mistake 4 — Deactivating All Zaps at Once

A simultaneous deactivation creates a simultaneous risk surface. If multiple scenarios have undetected issues, they all fail at the same time. Phase deactivations across two to three weeks.

Mistake 5 — Ignoring Execution Volume Increases

Make.com™ counts operations differently than Zapier counts tasks. A scenario that appears to consume the same number of operations as its Zap equivalent may consume significantly more if it uses iterators or aggregators. Validate your expected monthly operation count against your plan tier before the parallel window begins.

Frequently Asked Questions

How long does a Zapier-to-Make.com HR automation migration typically take?

For a mid-market HR team running 20–50 active Zaps, a disciplined migration takes four to eight weeks end-to-end: one to two weeks for auditing, one to two weeks for rebuilding, two weeks of parallel testing, and a final cutover week. Larger environments with 100+ Zaps or complex multi-step logic add proportional time.

Do I need to rebuild every Zap from scratch in Make.com™?

Yes — there is no automated import tool that reliably converts Zaps to Make.com™ scenarios. Each scenario must be rebuilt manually. The rebuild process forces a logic review that typically surfaces redundant or broken Zaps that were consuming operations without delivering value.

Will my HR data be safe during the migration?

Data safety during migration depends on parallel operation, not speed. Run Make.com™ scenarios alongside active Zaps using identical real triggers until you have confirmed output parity. Never deactivate a Zap before its Make.com™ replacement has processed at least a full week of live data without error.

How do I handle Zapier Formatter steps in Make.com™?

Zapier Formatter has equivalents across several Make.com™ tools: built-in text, number, and date functions within module field mapping cover most formatting tasks. Complex transformations — like multi-condition string parsing — can be handled with Make.com™’s native functions or a Code module running JavaScript, giving significantly more control than Formatter allows.

Can I migrate only some Zaps and keep others in Zapier?

Technically yes, but splitting your automation stack across two platforms increases maintenance complexity and licensing cost. A full migration executed in phases — low-risk, high-frequency workflows first, complex multi-step automations last — is almost always cleaner than maintaining a permanent hybrid state.

What happens to in-flight Zapier tasks during the cutover?

In-flight Zapier tasks — those triggered but not yet completed — will finish in Zapier regardless of when you deactivate a Zap. Schedule cutover during a low-volume window and allow a 24-hour overlap where both platforms are live before fully retiring each Zap.

Does Make.com™ offer better error handling than Zapier for HR workflows?

Make.com™ provides explicit error-handler routes attached directly to individual modules, incomplete execution logs, and automatic retry configuration — capabilities that Zapier’s task history does not match at the same granularity. For HR workflows where a missed trigger means a candidate doesn’t receive an offer letter or a new hire misses onboarding tasks, that precision is operationally significant.

Should I use Make.com™’s free plan during the migration testing phase?

No. Use a paid Make.com™ plan from the start of the migration. The free tier’s operation limits and absence of execution logs will artificially constrain testing and mask real-world performance. Run the full migration on the plan tier you intend to use in production so your performance benchmarks are accurate.

When should I bring in outside help for this migration?

Bring in a specialist when your Zapier environment includes more than 30 active Zaps, any multi-branch conditional logic, custom webhook integrations, or compliance-sensitive data flows involving candidate PII. The cost of an expert-guided migration is typically recovered within the first quarter through eliminated rework and faster time-to-value on Make.com™.

Next Steps

A completed migration gives you a cleaner, more observable HR automation stack — but the architectural decisions that determine long-term scalability and compliance posture sit upstream of platform choice. Revisit our parent guide on choosing the right HR automation platform architecture once your Make.com™ environment is stable.
