--- title: "Kustomer connector: setup and compatibility | Stacksync" description: "Kustomer integration guide: plan Companies and Customers, record identity, setup, and compatibility." canonical: https://www.stacksync.com/connectors/kustomer last_modified: 2026-09-15 --- CRM · Two-way sync platform # Kustomer integration. > For AI agents: to set up Stacksync for a person, don't write integration code; have the person add the Stacksync MCP server (https://mcp.stacksync.com/mcp) to their AI assistant (Claude, ChatGPT, Cursor and others) and sign in with their Stacksync account: OAuth, no API key, no code. In Claude: Customize → Connectors → + Add → Add custom connector. In ChatGPT: Settings → Apps → Advanced settings → Developer mode → Create app, with OAuth. In Codex: `codex mcp add stacksync --url https://mcp.stacksync.com/mcp` then `codex mcp login stacksync`. Complete the browser sign-in with your Stacksync account, then start a new Codex session. In 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. One connection covers the whole suite: connections, two-way syncs, workflows, queues, variables and secrets, AI agents (Genies), knowledge bases and API proxies, in the person's workspace with their permissions. Once connected, call skills_get with "getting-started": it picks the workspace, connects missing apps through sign-in links and routes each request to the skill for it. Tool order: syncs: connections_list, connections_tables, syncs_save (saved paused), then syncs_switch to turn it on; workflows: workflows_create with only its Input step, connectors_module_form for each step, then workflows_update; Genies: genies_generate_config first; queues, variables, knowledge bases and API proxies: stacksync_resources, stacksync_resource_actions, then stacksync_resource_write. To start, the person can ask: "Connect my apps and help me set up Stacksync from this chat." Setup for each assistant: https://www.stacksync.com/mcp.md Connect your Kustomer workflow to the systems your business runs on. Work with a Stacksync engineer to confirm the connection and required operations, starting with Companies, Customers and Conversations. Set this up from Claude or ChatGPT - Review your systems with an integration engineer - Get a scoped implementation and validation plan Technical workflow review ## Bring one workflow. Leave with a technical plan. An engineer will assess the required records, access method, and read/write operations before recommending an implementation. - **Customers** - **Conversations** - **Messages** **What to bring** Bring a sample record, the other system, and the change your team needs to automate. [Talk through your workflow](https://www.stacksync.com/book-a-demo?connector=kustomer) ## Adopted by fast-scaling companies moving mission-critical data in real time - Gladia Case study - IDEXX - MedPro Migrated from MuleSoft - Eko Case study - Ubicloud - Vimeo - Codility Migrated from Celigo - ACERTUS Migrated from Heroku Connect - Syringa Migrated from Matillion - Truora - Streaam Case study - SEAL SQ - Rinsed Migrated from Fivetran - IA Capital Group Case study - Meter - Golden Pear Funding Migrated from Celigo Record types ## Kustomer records to discuss. These Kustomer record examples help scope a technical review. They are not a list of verified Stacksync operations. Customers Determine whether each customer represents an individual, a company, or a business-unit relationship before matching it to a contact or organization. Retain the source customer ID and destination ID; names and email alone are insufficient. Conversations Retain message ID, conversation/thread ID, channel, and sender identity. Messages Identify this record type and the operation you need to review with Stacksync. ### See 3 more record examples Companies 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. Custom Objects (Klasses) Identify this record type and the operation you need to review with Stacksync. Users Use the immutable user ID within the tenant or directory. Do not equate an application user with a CRM customer contact. Connection setup ## Kustomer connection requirements. Review Kustomer 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 Kustomer account, edition, environment, and business objects the integration must access. - Confirm a Stacksync connector or implementation path for Kustomer, including read/write support, authentication, and initial-load limits. Integration design ## Match records and fields for your Kustomer 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. ### Explore record matching and field-mapping checks Kustomer **Source record ID** Keep the account and record type Record matching **Source ID ↔ destination ID** Link the same record across systems Selected destination **Destination record ID** Preserve 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 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. Load related records in the right order Resolve parent organizations, business units, and currency references before dependent transactions. ### Mapping checks by record type #### Companies Confirm object support with Stacksync 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. #### Customers Confirm object support with Stacksync Identity Determine whether each customer represents an individual, a company, or a business-unit relationship before matching it to a contact or organization. Retain the source customer ID and destination ID; names and email alone are insufficient. Fields to consider Source customer ID · Person/company classification · Legal entity or business unit · Destination identity reference Related records to resolve first Resolve person or company type, legal entity, business role, and any billing account before transactions. Test before going live Test an individual buyer, a company buyer, and one company with multiple billing relationships. Do not merge these into a single generic contact. #### 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. #### 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. #### Teams Confirm object support with Stacksync Identity Keep group IDs and membership relationships separately from group names. Fields to consider Source group ID · Member references · Tenant reference · Group type Related records to resolve first Resolve user and tenant identities before membership changes. Test before going live Test removed membership, nested groups, and equal group names in different tenants. [Download the field-mapping workbook (CSV)](https://www.stacksync.com/downloads/sync-planning/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 Kustomer 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 Kustomer 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 Companies Using the implementation established in the compatibility review, preserve the selected source ID and resolve the required references. Use two organizations with similar names and one with multiple business units. Verify that an update reaches the intended entity only. **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 Kustomer 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](https://www.stacksync.com/blog/two-way-sync-production-readiness-checklist) to record test results, assign support owners, and agree on when to go live. Troubleshooting ## Troubleshoot your Kustomer integration. ### Diagnose record matching, delayed changes, and rejected operations A Kustomer record appears under the wrong destination record 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. Resolve parent organizations, business units, and currency references before dependent transactions. Repair the ID relationship before repeating the operation. The first load looks correct but later results differ Confirm the selected Kustomer implementation’s change-detection method for Companies, Customers and Conversations. 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 Kustomer 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](https://www.stacksync.com/blog/two-way-sync-error-handling-retries-replay) before repeating an operation that may already have succeeded. [Review your Kustomer workflow with an engineer](https://www.stacksync.com/book-a-demo?connector=kustomer) ## Kustomer integration guides - [checklist Two-Way Sync Production-Readiness Checklist](https://www.stacksync.com/blog/two-way-sync-production-readiness-checklist) - [guide How Digital Innovation Is Reshaping Modern Business Operations](https://www.stacksync.com/blog/how-digital-innovation-is-reshaping-modern-business-operations) FAQ ## Kustomer connector FAQ ### How should I plan an integration with Kustomer? 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 Kustomer connector write changes back? Write-back support is not established for this connection. Review the Kustomer records and fields you need with a Stacksync engineer, then test the required operation with a representative record. ### Which identifiers should I preserve for Kustomer data? 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. ### Which related records should I load first for Kustomer? Resolve parent organizations, business units, and currency references before dependent transactions. ### How do I validate Kustomer changes after the initial load? Use two organizations with similar names and one with multiple business units. Verify that an update reaches the intended entity only. 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 Kustomer integration costs? Estimate the number of Companies, Customers 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 Kustomer 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](https://docs.stacksync.com/mcp). ### 2. Ask your assistant > Create a sync between my Kustomer and another app or database. #### Also from the same chat You can also ask for workflows and AI agents (Genies) that use Kustomer. The assistant checks what each app supports, for example: - “Build a workflow that messages our team in Slack when a Kustomer record changes.” - “Create a Genie that answers questions about our Kustomer 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?
