Why teams connect Ironclad and SAP S/4HANA

Bridge the tools people work in and the system the business runs on: real-time, two-way sync between Ironclad and SAP S/4HANA.

The ERP holds the records the business is run on, and it is rarely where day-to-day work happens. Ironclad is closer to the work, and the two often need the same facts about the same people, organizations, and transactions. Bridging them by hand, or by nightly file transfer, leaves each side out of date for hours at a time.

Stacksync syncs Signature Packets, Workflow Documents, Workflows, Records in Ironclad with Products / Materials, Billing Documents (Invoices), Deliveries, Journal Entries in SAP S/4HANA bi-directionally and in real time, with field-level mapping and rules for which system wins on conflict. Changes made where the work happens reach the system of record within seconds, and the reverse.

Common use cases

  • 01 Pull executed contract PDFs from Records attachments into a document store or archive as each workflow completes.
  • 02 Two-way sync Ironclad Records with a warehouse or ERP so executed-contract value, counterparty, renewal dates, and status stay current without manual re-keying.
  • 03 Keep supplier records aligned between S/4HANA procurement and third-party spend platforms.
  • 04 Push closed-won CRM opportunities into S/4HANA as sales orders without manual re-keying.

Common sync patterns

Where Ironclad faces customers and SAP S/4HANA carries account records

Order, invoice, or account status from SAP S/4HANA appears alongside the customer in Ironclad, so front-line teams answer from live data.

Where Ironclad collects payments: transactions post through

Payment events sync into SAP S/4HANA as they occur, keeping the enterprise records current without manual entry.

Where SAP S/4HANA is the HR or people system of record

Worker and organization data from SAP S/4HANA stays current in Ironclad, so the tools people use daily reflect the org as it actually is.

What you can sync between Ironclad and SAP S/4HANA

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 SAP S/4HANA 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. Customer / Supplier Roles Role-specific views of Business Partners mapped to CRM account types. Webhooks is specific to Ironclad and Customer / Supplier Roles to SAP S/4HANA — 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. Production Orders Manufacturing order status surfaced in planning and operations tools. Workflow Approvals is specific to Ironclad and Production Orders to SAP S/4HANA — 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. Business Partners Unified customer and supplier master records, the anchor entity for CRM-to-ERP account syncs. Signature Packets is specific to Ironclad and Business Partners to SAP S/4HANA — 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. Sales Orders Order headers and line items synced to CRMs and fulfillment systems as they are created or amended. Workflow Documents is specific to Ironclad and Sales Orders to SAP S/4HANA — 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. Purchase Orders Procurement documents shared with supplier portals and spend-management tools. Workflows is specific to Ironclad and Purchase Orders to SAP S/4HANA — 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. Products / Materials Material master data distributed to e-commerce, PIM, and CRM catalogs. Records is specific to Ironclad and Products / Materials to SAP S/4HANA — each maps to any object or custom field on the other side.

How changes propagate between Ironclad and SAP S/4HANA

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 SAP S/4HANA 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 SAP S/4HANA through its API, with automatic retries and rate-limit backoff.

SAP S/4HANA Ironclad Interval-based propagation

DetectionStacksync polls SAP S/4HANA for changes on an incremental schedule, reading only records changed since the previous pass. Polling on change timestamps exposed by the OData services.

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.
  • SAP S/4HANA: Subject to the platform's API rate limits, which vary by edition and communication arrangement.

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.
