Check the account access and change-detection requirements for your environment. Your system administrator can help confirm permissions before the first sync.

Connection method
REST API (Core API)
Account access
OAuth authorization via the Stacksync UI ("Connections" > "create new connection" > "Front" > "Authorize") — no coding required
How changes are detected
The Stacksync guide does not specify the change-detection mechanism. Confirm it for the selected objects.

Setup guides and technical references

Integration design

Match records and fields for your Front integration.

Decide which system owns case state and assignment. Model the requester, organization, comments, and attachments separately; preserve the visibility of private and public content.

Use your account’s actual field names when applying these matching and dependency checks.

Explore record matching and field-mapping checks
FrontSource record IDKeep the account and record type
Record matchingSource ID ↔ destination IDLink the same record across systems
Selected destinationDestination record IDPreserve its local key and rules
Conceptual identity model. Keep source and destination IDs linked so an update reaches the right record. Confirm the supported sync direction separately.
Match the same record in both systems
Keep Contact identity distinct from Account identity. Define the identifiers for group membership separately from the records that belong to the group.
Load related records in the right order
Resolve Contacts and Accounts before testing related group data. If the workflow needs another object, confirm its coverage before building the mapping.

Mapping checks by record type

Contacts

Supported

Identity
Use a stable person/contact ID and an explicit cross-system lookup. Email can change and can be shared, so treat it as a matching clue rather than a universal key.
Fields to consider
Source person ID · Display name · Email address · Organization reference · Consent state
Related records to resolve first
Resolve the organization relationship and any owner or consent references required by the destination.
Test before going live
Test an email change, two records sharing an email, and a person associated with multiple organizations.

Accounts

Supported

Identity
Retain the source company ID and the destination customer/company ID. Separate legal entities, subsidiaries, and business units; a shared name or web domain is insufficient.
Fields to consider
Source record ID · Legal or display name · Business-unit reference · Lifecycle status
Related records to resolve first
Resolve parent organizations, business units, and currency references before dependent transactions.
Test before going live
Use two organizations with similar names and one with multiple business units. Verify that an update reaches the intended entity only.

Conversations

Confirm object support with Stacksync

Identity
Retain message ID, conversation/thread ID, channel, and sender identity.
Fields to consider
Source message ID · Thread reference · Delivery state · Timestamp · Related record ID
Related records to resolve first
Resolve conversation, participant, and customer context before associating messages.
Test before going live
Test a delivery-state change, repeated message, private conversation, and reply linked to the correct thread.

Teammates

Confirm object support with Stacksync

Identity
Use the immutable user ID within the tenant or directory. Do not equate an application user with a CRM customer contact.
Fields to consider
Source user ID · Tenant reference · Account status · Group references
Related records to resolve first
Resolve tenant and group references and establish a protected administrative-account policy.
Test before going live
Test a renamed login, disabled account, missing group, and a user existing in two tenants.

Events

Supported

Identity
Keep the source event ID, source system, occurrence time, and ingestion time. Use an explicit duplicate-detection key.
Fields to consider
Source event ID · Event type · Occurred-at time · Related record ID · Payload version
Related records to resolve first
Resolve the related customer, user, or transaction identity without assuming the event ID is the entity ID.
Test before going live
Deliver the same event twice, then an older event after a newer one; verify duplicate and ordering behavior.

Download the field-mapping workbook (CSV) to capture the actual API fields, matching keys, owners, and test results. Use it as you build with your team or a Stacksync engineer.

Setup and validation

Validate the Front integration in four steps.

A ticket update retains its participants and conversation history, and an integration retry does not send a second customer reply.

View the four setup tests and expected results

  1. Confirm the intended Front account and grant

    Use the documented setup with the intended account and environment. Check that the authorizing user can grant access to the selected objects; test reauthorization without changing the mapped record identity.

    Expected result: The connection reaches the intended account, and the integration owner can renew or revoke the grant through the agreed procedure.

  2. Prove the exact support context you need

    Select one documented object, one intended editable field, and one relationship. Validate their behavior in the actual account.

    Expected result: The demonstrated object and operation satisfy the workflow; the plan does not assume that every Front object is included.

  3. Test writes in the directions you need

    Select one eligible Front object and writable field. Test the required create/update direction, an invalid value, and a repeated delivery. Check object-specific restrictions before enabling the return path.

    Expected result: The selected operation is confirmed, addresses the intended record, and exposes rejected values for repair.

  4. Test recovery and name the support owner

    Interrupt a non-production transfer, restore the connection, and reconcile the selected Front records. When using Stacksync’s Retry to sync action, check the latest source value: the retry re-reads current source state rather than replaying an immutable historical event.

    Expected result: The records have the expected current values, repeated delivery creates no duplicate business record, and your team knows who handles unresolved errors.

Use the production-readiness checklist to record test results, assign support owners, and agree on when to go live.

Troubleshooting

Troubleshoot your Front integration.

Diagnose record matching, delayed changes, and rejected operations
The desired support workflow needs an unlisted object
Compare the request with the four documented object types and confirm additional coverage. The setup guide does not specify all field permissions or change-detection behavior.
The first load looks correct but later results differ
The Stacksync guide does not specify the change-detection mechanism. Confirm it for the selected objects. Measure the original source change, its capture, and the destination observation separately. Confirm whether the affected object is incremental, historical-only, or subject to a special refresh cycle.
One operation succeeds while another is rejected
Check the specific Front object, field permissions, required references, and allowed operation. A successful read does not establish that a create, update, deletion, or business action is available.

Review retry, replay, and recovery behavior before repeating an operation that may already have succeeded.

Front integration guides

FAQ

Front connector FAQ

How should I plan an integration with Front?

Match the published Accounts, Contacts, Contact Groups, and Events inventory to the requested support workflow. Stacksync supports two-way sync for eligible objects. Start with one workflow, agree on which fields each system owns, then test initial data, later changes, and recovery before expanding.

Can the Front connector write changes back?

Stacksync supports reads and writes for eligible Front objects. Check the selected fields, account permissions, and the other system’s connector. Select one documented object, one intended editable field, and one relationship. Validate their behavior in the actual account.

Which identifiers should I preserve for Front data?

Keep Contact identity distinct from Account identity. Define the identifiers for group membership separately from the records that belong to the group.

Which related records should I load first for Front?

Resolve Contacts and Accounts before testing related group data. If the workflow needs another object, confirm its coverage before building the mapping.

What should I check if Front data is missing or delayed?

Compare the request with the four documented object types and confirm additional coverage. The setup guide does not specify all field permissions or change-detection behavior.

What should I include when estimating Front integration costs?

Estimate the number of Contacts, Accounts and Conversations records, the history to load, ongoing changes, and required environments. Include API access, the integration service, destination storage or processing, and the work to maintain mappings and recover from errors. Review current provider pricing against that workload, including any account or API upgrades.

AI assistant

Set up Front from Claude or ChatGPT

Connect the Stacksync MCP server to your AI assistant, then ask for the sync in plain language. You only sign in; there is no code to write and no API key to paste.

1. Add the Stacksync MCP server

Server URL

https://mcp.stacksync.com/mcp

In Claude

  1. Open Customize → Connectors, select + Add, then Add custom connector.
  2. Name it Stacksync and enter https://mcp.stacksync.com/mcp.
  3. Select Connect, sign in to Stacksync and choose your workspace.

In ChatGPT

  1. Open Settings → Apps → Advanced settings and turn on Developer mode.
  2. Select Create app, name it Stacksync, enter https://mcp.stacksync.com/mcp and choose OAuth.
  3. Sign in to Stacksync, then enable Stacksync from the tools menu in a chat.
Set up Codex or Claude Code

Codex

codex mcp add stacksync --url https://mcp.stacksync.com/mcp
codex mcp login stacksync

Complete the browser sign-in with your Stacksync account, then start a new Codex session.

Claude Code

claude mcp add --transport http stacksync https://mcp.stacksync.com/mcp

Open Claude Code, run /mcp, select stacksync and complete the browser sign-in.

Then ask: “List my Stacksync workspaces.” Sign-in connects your assistant; it does not create a sync yet.

Claude Code, Codex, Cursor, VS Code, Windsurf, Gemini CLI and other assistants: setup steps in the docs.

2. Ask your assistant

Create a sync between my Front and another app or database.

Also from the same chat

You can also ask for workflows and AI agents (Genies) that use Front. The assistant checks what each app supports, for example:

  • “Build a workflow that messages our team in Slack when a Front record changes.”
  • “Create a Genie that answers questions about our Front data in Slack.”

What happens next

  • Signs you in with your Stacksync login (OAuth). No API key is pasted into the chat.
  • Gives you a secure sign-in link for each app it connects; you open it and sign in to that app.
  • Builds the sync with your permissions in Stacksync, nothing more. Turn on Ask before every change in the MCP settings to approve each change first.
