Two-way sync
Changes in Attio or Ironclad instantly reflect in both systems. No stale data, no manual imports.
Keep Attio and Ironclad in sync without custom scripts. Cut weeks of integration work, eliminate silent data drift, and give your team a single, reliable source of truth.
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 Workflow Documents, Workflows, Records, Entities in Ironclad to Custom objects, People, Companies, Users in Attio with bi-directional, real-time sync. Activity and record changes in Ironclad update the matching contact or account in Attio, and CRM data flows the other way wherever Ironclad can store and use it.
Enriched fields land directly on records in Attio, and refreshes keep them from going stale.
Charges, refunds, and subscription changes appear on the account in Attio, so revenue context lives with the relationship.
Owner, lifecycle stage, or account details from Attio sync into Ironclad, so people working there have the context without switching tools.
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.
| Attio objects | Ironclad objects | How this pairing syncs | |
|---|---|---|---|
| Users Synced with incremental and full sync per the Stacksync docs. | Obligations Post-signature commitments, milestones, and renewal dates tied to contracts; synced two-way to drive renewal, compliance, and finance reporting in downstream systems. | Users is specific to Attio and Obligations to Ironclad — each maps to any object or custom field on the other side. | |
| Deals Pipeline records; read out for revenue reporting and written to from automation. | 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. | Deals is specific to Attio and Webhooks to Ironclad — each maps to any object or custom field on the other side. | |
| Workspaces Synced with incremental and full sync per the Stacksync docs. | 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. | Workspaces is specific to Attio and Workflow Approvals to Ironclad — each maps to any object or custom field on the other side. | |
| Custom objects Workspace-defined objects that behave like standard ones in the API. | 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. | Custom objects is specific to Attio and Signature Packets to Ironclad — each maps to any object or custom field on the other side. | |
| People Standard person object; synced with marketing tools and warehouse person tables. | Workflow Documents Draft and executed documents attached to a workflow; retrieved to pull generated or signed files out into a document store or archive. | People is specific to Attio and Workflow Documents to Ironclad — each maps to any object or custom field on the other side. | |
| Companies Standard company object; matched to billing and product accounts in two-way syncs. | 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. | Companies is specific to Attio and Workflows to Ironclad — each maps to any object or custom field on the other side. |
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.
DetectionAttio notifies Stacksync of record changes through webhook events. Webhooks on record and list-entry events, with polling as a fallback.
DeliveryEach detected change is written to Ironclad through its API, with automatic retries and rate-limit backoff.
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.

Configure and sync within minutes, no code. Whether you sync 50k or 100M+ records, Stacksync handles the queues, infra, and plumbing. Integrations are non-invasive and need zero setup on your systems.
Authenticate Attio and Ironclad with each platform's native method — OAuth, API keys, or service accounts — plus secure options like SSH tunneling, IP whitelisting, and VPC peering.
Pick the Attio and Ironclad objects to sync — Stacksync auto-detects both schemas, including custom fields where the platform exposes them. Sync to existing tables, or let Stacksync create new ones with ideal data types.
Fields map automatically even when names and types differ. Stacksync handles transformation and type casting for you, zero configuration required.
Yes. Stacksync provides a managed, real-time two-way integration between Attio and Ironclad: authenticate both systems, choose the objects to sync (such as Attio's Users and Deals), map fields visually, and changes propagate both ways in milliseconds — no code required.
Change detection on Attio: Webhooks on record and list-entry events, with polling as a fallback. 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. Each detected change propagates to the other side in milliseconds, with field-level conflict resolution and an inspectable event log.
On the Ironclad side: Workflow Documents, Workflows, Records, Entities, plus custom fields where Ironclad exposes them. On the Attio side: Custom objects, People, Companies, Users. Stacksync auto-detects both schemas and converts types between the two systems.
Yes. Each object mapping can be bidirectional or restricted to a single direction (both systems accept writes). Read-only mirrors, one-way pushes, and full two-way sync can be mixed in the same integration.
Common patterns for Attio and Ironclad: Where Ironclad supplies contact or company data; Where Ironclad processes payments; Where Ironclad can store CRM context: fields kept current. Enriched fields land directly on records in Attio, and refreshes keep them from going stale.
Attio: REST API. Authentication: Guided in-app connection ("Attio CRM" connection created in a few clicks, "without any coding required"); the docs do not name the underlying auth mechanism (OAuth vs API key). Ironclad: 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. Stacksync manages authentication, retries, and rate limits on both sides.
