Why teams connect Ironclad and Kustomer
Sync what happens in Ironclad with the customer records in Kustomer, in real time and in both directions.
The CRM is supposed to be the record of every customer relationship, but customer-relevant information also accumulates in the other tools a team runs. Whatever Ironclad holds or produces that touches a customer, whether conversations, payments, replies, enriched data, or notes, the CRM only benefits if it arrives without someone copying it over.
Stacksync connects Workflows, Records, Entities, Obligations in Ironclad to Notes, Customers, Conversations, Messages in Kustomer with bi-directional, real-time sync. Activity and record changes in Ironclad update the matching contact or account in Kustomer, and CRM data flows the other way wherever Ironclad can store and use it.
Common use cases
- 01 Stream workflow approval and signature webhook events into an operational database for cycle-time, bottleneck, and SLA reporting across the contract lifecycle.
- 02 Push Obligations and renewal dates from Ironclad into a finance or task system so post-signature commitments and renewals are tracked and actioned on time.
- 03 Push order and shipment records from commerce systems into Kustomer custom objects so agents answer order-status questions without switching tools
- 04 Mirror conversations and satisfaction data into a warehouse for support analytics and agent performance reporting
Common sync patterns
Where Ironclad supplies contact or company data
Enriched fields land directly on records in Kustomer, and refreshes keep them from going stale.
Where Ironclad processes payments
Charges, refunds, and subscription changes appear on the account in Kustomer, so revenue context lives with the relationship.
Where Ironclad can store CRM context: fields kept current
Owner, lifecycle stage, or account details from Kustomer sync into Ironclad, so people working there have the context without switching tools.
What you can sync between Ironclad and Kustomer
Representative objects on each side — any object or custom field can map to any target. Schemas are auto-detected; types are converted between the two systems.
| Ironclad objects | Kustomer objects | How this pairing syncs | |
|---|---|---|---|
| Webhooks Event subscriptions that push workflow, approval, signature, document, and comment changes to Stacksync in near real time; created, listed, and deleted through the API across 40+ event types. | Custom Objects (Klasses) Structured external records such as orders and subscriptions synced in to appear on the customer timeline. | Webhooks is specific to Ironclad and Custom Objects (Klasses) to Kustomer — each maps to any object or custom field on the other side. | |
| Workflow Approvals Per-workflow approval requests and their state; read to report approval status and cycle time, and status changes arrive live through the workflow_approval_status_changed event. | Users Agent records map conversation ownership to people in other systems. | Workflow Approvals is specific to Ironclad and Users to Kustomer — each maps to any object or custom field on the other side. | |
| Signature Packets The e-signature packets on a workflow (sent, signatures collected, fully signed); read to track signing progress, with packet events delivered by webhook for real-time status. | Teams Team assignments support routing parity and reporting. | Signature Packets is specific to Ironclad and Teams to Kustomer — each maps to any object or custom field on the other side. | |
| Workflow Documents Draft and executed documents attached to a workflow; retrieved to pull generated or signed files out into a document store or archive. | Tags Labels on conversations and customers sync for categorization and analytics. | Workflow Documents is specific to Ironclad and Tags to Kustomer — each maps to any object or custom field on the other side. | |
| Workflows The core unit of Ironclad: a live contract process (NDA, MSA, order form) moving through creation, review, approval, and signature. Launched via POST, updated via PATCH, and read for status, so contract processes move two-way between Ironclad and a database, CRM, or ERP. | Notes Internal annotations carry context alongside synced conversations. | Workflows is specific to Ironclad and Notes to Kustomer — each maps to any object or custom field on the other side. | |
| Records The Repository of executed and stored contracts with metadata (value, counterparty, key dates, type) and attachments; full create, read, update, and delete so signed-contract data and PDFs sync to a warehouse, ERP, or CRM. | Customers The central record whose timeline aggregates every interaction; external attributes sync onto it. | Records is specific to Ironclad and Customers to Kustomer — each maps to any object or custom field on the other side. |
How changes propagate between Ironclad and Kustomer
Each direction of the sync is driven by what the source system can signal and what the destination accepts — detection, delivery, and expected latency below.
Ironclad Kustomer Sub-second propagation
DetectionIronclad notifies Stacksync of record changes through webhook events. Native webhook subscriptions (POST /webhooks) fire on 40+ workflow, approval, signature, document, and comment events, and Ironclad retries a failing.
DeliveryEach detected change is written to Kustomer through its API, with automatic retries and rate-limit backoff.
Kustomer Ironclad Sub-second propagation
DetectionKustomer notifies Stacksync of record changes through webhook events. Outbound webhooks on record events, plus polling for backfill.
DeliveryEach detected change is written to Ironclad through its API, with automatic retries and rate-limit backoff.
Rate-limit considerations
- Ironclad: Limits are enforced per account per minute by endpoint: GET Workflows 400 and POST/PATCH Workflows 40; GET Records 600 and POST/PATCH Records 200; GET Entities 600 and POST/PATCH Entities 200; Webhooks 600; all other endpoints 800. Exceeding a limit returns HTTP 429, and Ironclad recommends exponential backoff with jitter.
- Kustomer: Subject to the platform's API rate limits.

How the Ironclad and Kustomer connectors work
Ironclad
- Integration surface
- REST/JSON Public API (CLM API) at https://na1.ironcladapp.com/public/api/v1 (NA1 and EU1 regions plus a demo/sandbox), with a native Webhooks subscription API; described by an OpenAPI 3.1 spec.
- Authentication
- OAuth 2.0 - Authorization Code grant (PKCE for public clients) and Client Credentials grant for server-to-server; access tokens are Bearer, expire after 6 hours, and every endpoint is gated by a resource scope. The legacy static API bearer token was deprecated on 2024-11-22.
- Change detection
- Native webhook subscriptions (POST /webhooks) fire on 40+ workflow, approval, signature, document, and comment events, and Ironclad retries a failing endpoint up to 10 times over about 13.6 hours with exponential backoff. Otherwise poll the list endpoints by last-updated. There is no database change-data-capture log.

FAQ
Ironclad and Kustomer integration FAQ
-
Yes. Stacksync provides a managed, real-time two-way integration between Ironclad and Kustomer: authenticate both systems, choose the objects to sync (such as Ironclad's Webhooks and Workflow Approvals), map fields visually, and changes propagate both ways in milliseconds — no code required.
-
Ironclad: Workflows are the core unit - a live contract process (create, review, approve, sign) - while Records hold the executed contracts stored in the Ironclad Repository. Kustomer: API keys are issued as role-scoped bearer tokens, so integration access can be limited to the specific object types a sync touches. Stacksync's field mapping accounts for these differences between Ironclad and Kustomer without custom code.
-
Stacksync is SOC 2 Type II and ISO 27001 certified with HIPAA BAA support. Data is encrypted in transit, and a zero-persistent-storage architecture means Ironclad and Kustomer records are not retained after a sync operation.
-
Stacksync pricing is usage-based and starts at $1,000/month, including the managed Ironclad and Kustomer connectors, real-time two-way sync, monitoring, and support. That replaces building and maintaining a custom Ironclad–Kustomer integration in-house.
-
Yes — Stacksync ships production-grade connectors for both Ironclad and Kustomer. The connectors handle authentication, schema detection, rate limits, and retries; you configure the sync, and Stacksync operates it.
-
Change detection on Ironclad: Native webhook subscriptions (POST /webhooks) fire on 40+ workflow, approval, signature, document, and comment events, and Ironclad retries a failing endpoint up to 10 times over about 13.6 hours with exponential backoff. Otherwise poll the list endpoints by last-updated. There is no database change-data-capture log. On Kustomer: Outbound webhooks on record events, plus polling for backfill. Each detected change propagates to the other side in milliseconds, with field-level conflict resolution and an inspectable event log.
