Record types

Close records to discuss.

These Close record examples help scope a technical review. They are not a list of verified Stacksync operations.

Leads
Retain the lead ID and record its relationship to any converted contact or company.
Contacts
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.
Opportunities
Keep the opportunity/deal ID separate from any later order or invoice ID.
See 3 more record examples
Activities
Keep the source event ID, source system, occurrence time, and ingestion time. Use an explicit duplicate-detection key.
Tasks
Use a stable task/work-item ID and preserve its project or parent-ticket reference.
Custom Activities
Identify this record type and the operation you need to review with Stacksync.
Connection setup

Close connection requirements.

Review Close access and the operations your workflow needs with Stacksync. The vendor API reference below can help your administrator prepare for that discussion.

Prepare access and scope for the engineering review
  • Identify the Close account, edition, environment, and business objects the integration must access.
  • Confirm a Stacksync connector or implementation path for Close, including read/write support, authentication, and initial-load limits.

Integration design

Match records and fields for your Close integration.

Choose the owner of customer details, qualification, and commercial status separately. A customer update, a won deal, and an approved order represent different business decisions.

Use these design questions to prepare a representative record and the business rules your integration must preserve.

Mapping checks by record type

Contacts

Confirm object support with Stacksync

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.

Leads

Confirm object support with Stacksync

Identity
Retain the lead ID and record its relationship to any converted contact or company.
Fields to consider
Source lead ID · Qualification status · Owner reference · Conversion reference
Related records to resolve first
Resolve owner and campaign references and decide how conversion changes the identity relationship.
Test before going live
Convert a test lead after the first load and verify that it does not create a duplicate person or orphan its activity.

Opportunities

Confirm object support with Stacksync

Identity
Keep the opportunity/deal ID separate from any later order or invoice ID.
Fields to consider
Source deal ID · Stage · Amount and currency · Expected close date · Company reference
Related records to resolve first
Map the customer and sales pipeline before the opportunity; map stage values deliberately.
Test before going live
Test a reopened won deal, a stage with no destination equivalent, and an amount using a different currency.

Activities

Confirm object support with Stacksync

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.

Tasks

Confirm object support with Stacksync

Identity
Use a stable task/work-item ID and preserve its project or parent-ticket reference.
Fields to consider
Source task ID · Parent reference · Assignee · Status · Due date
Related records to resolve first
Resolve project, user, and parent-item references before the task.
Test before going live
Test a reassignment, an unsupported status transition, a deleted parent, and a due date across time zones.

Users

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.

Setup and validation

Validate the Close integration in four steps.

A changed contact detail updates the existing person; a sales-state change reaches only the downstream process approved to act on it.

View the four setup tests and expected results

  1. Verify Close credentials and resource scope

    After confirming an implementation path, validate the selected access method with the intended account, region or workspace, and resource scope. Record the credential owner and renewal procedure, then demonstrate access to one selected object.

    Expected result: The selected resource is accessible through the approved credential, with the renewal and revocation procedure assigned to an owner.

  2. Test record matching for Contacts

    Using the implementation established in the compatibility review, preserve the selected source ID and resolve the required references. Test an email change, two records sharing an email, and a person associated with multiple organizations.

    Expected result: A changed contact detail updates the existing person; a sales-state change reaches only the downstream process approved to act on it.

  3. Test the operation your workflow needs

    Review one Close record with a Stacksync engineer. Confirm how it should reach the other system, how often it must update, and whether your workflow needs reads, creates, or updates. Test those operations before expanding the integration.

    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

    For the confirmed implementation, interrupt a non-production transfer and restore access. Establish whether recovery uses the current source state or a stored historical event, and verify that repeated delivery preserves record identity.

    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 Close integration.

Diagnose record matching, delayed changes, and rejected operations
A Close record appears under the wrong destination record
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. Resolve the organization relationship and any owner or consent references required by the destination. Repair the ID relationship before repeating the operation.
The first load looks correct but later results differ
Confirm the selected Close implementation’s change-detection method for Contacts, Leads and Opportunities. Compare later changes with the original source rather than using a successful initial copy as evidence of ongoing capture.
One operation succeeds while another is rejected
Check the specific Close 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.

FAQ

Close connector FAQ

How should I plan an integration with Close?

Choose the owner of customer details, qualification, and commercial status separately. A customer update, a won deal, and an approved order represent different business decisions. Confirm the connection and read/write operations with Stacksync. Start with one workflow, agree on which fields each system owns, then test initial data, later changes, and recovery before expanding.

Can the Close connector write changes back?

Write-back support is not established for this connection. Review the Close records and fields you need with a Stacksync engineer, then test the required operation with a representative record.

Which identifiers should I preserve for Close data?

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.

Which related records should I load first for Close?

Resolve the organization relationship and any owner or consent references required by the destination.

How do I validate Close changes after the initial load?

Test an email change, two records sharing an email, and a person associated with multiple organizations. A changed contact detail updates the existing person; a sales-state change reaches only the downstream process approved to act on it.

What should I include when estimating Close integration costs?

Estimate the number of Contacts, Leads and Opportunities 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 Close 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 Close and another app or database.

Also from the same chat

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

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

New to Stacksync? Create an account first, then sign in from your assistant.
