Example workflow

Support case or ticket process handoff

Use writable fields from the connected accounts. Read values from read-only fields without writing changes back to them, and define deletion handling separately.

Starting eventA change involving HubSpot Tasks or Zendesk Tickets needs a defined result in the other system.

  1. Start with HubSpot Tasks and Zendesk Tickets. Use the record-matching and field-ownership rules from your mapping worksheet.

  2. Resolve requester, organization, team, and status references before ticket updates.

  3. Test a normal update and one failed or repeated update in the supported direction. Keep both record IDs with the test results.

What to verifyEscalate the same ticket twice, close one of several tasks, and verify that private ticket content is not copied into a public work item.

Why teams connect HubSpot and Zendesk

Put your HubSpot and Zendesk data to work

Start with the work your team needs to complete: keep records up to date, make operational data available for reporting, or move data to a new system. Choose one HubSpot and Zendesk workflow to test, define what success looks like, and decide who handles failed updates.

  • Push product signup and usage events into HubSpot contact properties to drive lifecycle marketing segmentation.

  • Write warehouse-computed lead and account scores back to HubSpot properties on a schedule or in near real time.

  • Sync tickets, users, and organizations into Postgres so support analytics run on SQL instead of repeated API pulls.

  • Write CRM account tier, owner, and renewal data onto Zendesk organizations and ticket fields so agents see context in the ticket.

What records can you sync?

Start with the records your workflow needs. Check each system’s read and write requirements before mapping fields.

Business process

Tasks / Tickets

Support-to-work-item handoff: Zendesk Tickets provides context for HubSpot Tasks. These are related records, not equivalent entities.

Use writable fields from the connected accounts. Read values from read-only fields without writing changes back to them, and define deletion handling separately.

HubSpot
Documented record · ✅ Supported
Zendesk
Documented record · ✅ Supported
Record identity
Retain separate ticket and task IDs with an explicit relationship; several tasks may resolve one ticket.
Field ownership
Choose which ticket conditions create a work item and which task outcomes may update the support case.

Fields to include

  • Source record reference
  • Destination record reference
  • Approved handoff state
  • Duplicate-detection key

Compare integration approaches

This pair can involve both record sync and process handoffs. Keep the Tasks / Tickets relationship explicit: copying fields and creating a downstream business transaction require different validation.

Stacksync managed sync

Best fit
Two-way sync for supported objects. Choose the records, writable fields, and permissions for your workflow.
Operating responsibility
Fits ongoing record synchronization when the required operations are supported. Add workflow steps for approvals or business actions that go beyond copying fields.
Before you choose
Check record matching: Retain separate ticket and task IDs with an explicit relationship; several tasks may resolve one ticket. Verify field coverage, deletion handling, and how changes are detected.

Native vendor integration

Best fit
A vendor-built integration may fit if it supports your HubSpot and Zendesk record types.
Operating responsibility
Can reduce setup for a supported workflow. You may need another method for records or business steps it does not cover.
Before you choose
First check whether either vendor offers this integration. If available, verify Tasks / Tickets, update direction, account tier, and related-record handling.

Custom API or workflow

Best fit
Consider explicit orchestration for the Tasks / Tickets handoff.
Operating responsibility
Provides control over business steps; the team owns credentials, version changes, error queues, and reconciliation.
Before you choose
Verify endpoint permissions, pagination, quotas, duplicate detection, and failure recovery.

File or scheduled snapshot

Best fit
Consider for a one-time HubSpot / Zendesk migration or a reporting need with an explicit freshness window.
Operating responsibility
Can simplify a bounded transfer; later changes and deletion history require another extraction or a separately designed incremental process.
Before you choose
Record the extraction cutoff, source IDs, encoding, date/number formats, and reconciliation totals.

Workflow scenarios and expected results

Support case or ticket process handoff

Use writable fields from the connected accounts. Read values from read-only fields without writing changes back to them, and define deletion handling separately.

Starting event: A change to the selected Tasks or Tickets record needs a defined result in the other system.

  1. Start with HubSpot Tasks and Zendesk Tickets. Use the record-matching and field-ownership rules from your mapping worksheet.
  2. Resolve requester, organization, team, and status references before ticket updates.
  3. Test a normal update and one failed or repeated update in the supported direction. Keep both record IDs with the test results.

Expected result: Escalate the same ticket twice, close one of several tasks, and verify that private ticket content is not copied into a public work item.

If it fails: Check whether a reply or notification was already sent before replaying ticket actions.

Company sync test

Object-specific availability and field permissions determine this mapping. Use the restrictions shown for each record type.

Starting event: A change to the selected Company or Organizations record needs a defined result in the other system.

  1. Start with HubSpot Company and Zendesk Organizations. Use the record-matching and field-ownership rules from your mapping worksheet.
  2. Resolve parent organizations, business units, and currency references before dependent transactions.
  3. Test a normal update and one failed or repeated update in the supported direction. Keep both record IDs with the test results.

Expected result: Use two organizations with similar names and one with multiple business units. Verify that an update reaches the intended entity only.

If it fails: Repair the cross-system ID relationship before retrying dependent records; do not merge companies solely to remove a sync error.

Support case or ticket sync test

Use writable fields from the connected accounts. Read values from read-only fields without writing changes back to them, and define deletion handling separately.

Starting event: A change to the selected Ticket or Tickets record needs a defined result in the other system.

  1. Start with HubSpot Ticket and Zendesk Tickets. Use the record-matching and field-ownership rules from your mapping worksheet.
  2. Resolve requester, organization, team, and status references before ticket updates.
  3. Test a normal update and one failed or repeated update in the supported direction. Keep both record IDs with the test results.

Expected result: Test a merged ticket, a private note, a reopened case, and an attachment with restricted access.

If it fails: Check whether a reply or notification was already sent before replaying ticket actions.

Plan the customer lifecycle across HubSpot and Zendesk

Validate the selected objects and operations even where connector-level direction is documented.

Starting event: A customer-facing change in HubSpot needs operational context in Zendesk.

  1. Select the relevant Contact or Company records and identify whether the downstream relationship is a person, a company, a deal, or a reporting row.
  2. Define which lifecycle transitions are informative and which should request a downstream action. Keep conversion and merge history connected to stable IDs.
  3. Choose a representative reopened deal, changed contact identity, or reassigned account to test the handoff before expanding.

Expected result: The relationship survives a lifecycle change without creating a duplicate customer or triggering an unintended business action.

If it fails: Inspect merge/conversion history and existing destination records before replaying a lifecycle transition.

Initial load and acceptance testing

Keep both record IDs with the expected and actual result. Reconcile the same filters and time window in each system.

Tasks / Tickets

Test case

Escalate the same ticket twice, close one of several tasks, and verify that private ticket content is not copied into a public work item.

Expected result

The expected support case or ticket relationship is preserved with no duplicate action or unintended write.

Company / Organizations

Test case

Use two organizations with similar names and one with multiple business units. Verify that an update reaches the intended entity only.

Expected result

The expected company relationship is preserved with no duplicate action or unintended write.

Ticket / Tickets

Test case

Test a merged ticket, a private note, a reopened case, and an attachment with restricted access.

Expected result

The expected support case or ticket relationship is preserved with no duplicate action or unintended write.

Users / Users

Test case

Test a renamed login, disabled account, missing group, and a user existing in two tenants.

Expected result

The expected application user or identity relationship is preserved with no duplicate action or unintended write.

Direction and permissions

Test case

Check that each connected account can read and write the chosen objects. Exercise both directions with a test record before enabling production changes.

Expected result

Only an approved, supported direction and permitted fields are written.

Freshness and reconciliation

Test case

Measure source and destination times for the selected records under normal load and a burst. Reconcile IDs and values using the same filters and cutoff.

Expected result

The process meets its agreed freshness target and reconciliation has no unexplained differences.

Failed updates, retries and recovery

Start with the failed record and the destination error, then inspect the source value, field requirements, and access.

Rejected or repeated support case or ticket change

Investigate

Inspect HubSpot Tasks and Zendesk Tickets, their IDs, and the destination error.

Next action

Check whether a reply or notification was already sent before replaying ticket actions.

Rejected or repeated company change

Investigate

Inspect HubSpot Company and Zendesk Organizations, their IDs, and the destination error.

Next action

Repair the cross-system ID relationship before retrying dependent records; do not merge companies solely to remove a sync error.

Rejected or repeated support case or ticket change

Investigate

Inspect HubSpot Ticket and Zendesk Tickets, their IDs, and the destination error.

Next action

Check whether a reply or notification was already sent before replaying ticket actions.

A record type or update is unavailable

Investigate

Check the HubSpot and Zendesk connector guides, account permissions, and any operations marked On Request.

Next action

Ask the integration team to confirm a supported way to handle that record. Verify whether it needs connector configuration or a separate workflow step.

Source and destination disagree after a retry

Investigate

Compare current source values, destination validation, identity mappings, and any side effects already completed.

Next action

Stacksync issue retry reads the current source state. Decide the intended state before retrying or reverting; reconcile downstream effects separately.

Read the Stacksync issues dashboard guide for retry and revert behavior.
