Why teams connect Ramp and SAP

Keep Ramp and SAP agreeing on customers, invoices, and balances, whether they split the finance workload or one is replacing the other.

A dedicated finance tool and an ERP end up side by side for practical reasons: a subsidiary runs lighter software than headquarters, billing runs in a specialist system while the enterprise system holds the wider view, or the company is mid-migration and both are live. Whatever the split, the two systems describe overlapping customers and transactions, and that overlap drifts without a live connection.

Stacksync syncs General Ledger Accounts, Transactions, Cards, Users in Ramp with Inventory / Stock, Cost Centers, Business Partners, Materials (Products) in SAP in real time and in both directions. You decide which system wins on which field, and every change made in one is reflected in the other within seconds instead of at the next batch run.

Common use cases

  • 01 Mirror Bills and their approval and payment state into an AP or ERP system, marking each one ready-to-sync then synced to keep both ledgers reconciled.
  • 02 Read Reimbursements into a finance database for cross-entity expense reporting and reconciliation without manual CSV exports.
  • 03 Publish plant-level inventory to e-commerce and planning systems on change or on schedule.
  • 04 Replicate journal entries and billing documents to a warehouse for finance analytics without loading the ERP.

Common sync patterns

Subsidiary to headquarters

Where Ramp serves a business unit and SAP is the group system, transactions and customer records roll up continuously, so consolidation starts from live data.

Where Ramp handles billing: invoices land in SAP

Invoices and payment activity from the billing side post through to the enterprise system automatically.

Migration without a hard cutover

When one system is replacing the other, run both in parallel with records matching until the switch is complete.

What you can sync between Ramp and SAP

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.

Ramp objects SAP objects How this pairing syncs
Reimbursements Out-of-pocket expense claims; read for reporting and marked ready-to-sync then synced to the ERP. Materials (Products) Item master with plant and sales views, synced to commerce, PLM, and CRM systems. Reimbursements is specific to Ramp and Materials (Products) to SAP — each maps to any object or custom field on the other side.
Bills Accounts-payable bills; created, updated, approved, and paid, then posted ready-to-sync and synced to accounting. Sales Orders Order documents written from external channels and read for status and fulfillment. Bills is specific to Ramp and Sales Orders to SAP — each maps to any object or custom field on the other side.
Vendors Supplier records under the accounting namespace; uploaded and updated for AP matching and payments. Purchase Orders Procurement documents synced with supplier portals and spend tools. Vendors is specific to Ramp and Purchase Orders to SAP — each maps to any object or custom field on the other side.
Funds (Spend Controls) Spend controls governing card usage; read and created via the funds API to enforce budgets per user, department, or program. Outbound Deliveries Shipment documents synced to WMS, carriers, and customer portals. Funds (Spend Controls) is specific to Ramp and Outbound Deliveries to SAP — each maps to any object or custom field on the other side.
General Ledger Accounts Chart-of-accounts entries uploaded from the ERP; accounting codings are posted back against transactions and bills. Billing Documents Invoices read for AR status and replicated for revenue reporting. General Ledger Accounts is specific to Ramp and Billing Documents to SAP — each maps to any object or custom field on the other side.
Transactions Card purchase records with merchant, amount, and state; read for spend/GL sync and written back via accounting codings and sync status. GL Accounts and Journal Entries Financial postings replicated to warehouses for group finance analytics. Transactions is specific to Ramp and GL Accounts and Journal Entries to SAP — each maps to any object or custom field on the other side.

How changes propagate between Ramp and SAP

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.

Ramp SAP Sub-second propagation

DetectionRamp notifies Stacksync of record changes through webhook events. Signed webhooks (HMAC-SHA256 X-Ramp-Signature) for bill, transaction, reimbursement, vendor, and user events.

DeliveryEach detected change is written to SAP through its API, with automatic retries and rate-limit backoff.

SAP Ramp Sub-second propagation

DetectionSAP notifies Stacksync of record changes through webhook events. Business events via SAP Event Mesh on S/4HANA.

DeliveryEach detected change is written to Ramp through its API, with automatic retries and rate-limit backoff.

Rate-limit considerations

  • Ramp: 200 requests per 10-second rolling window per source IP; exceeding it returns 429 Too Many Requests, and requests running over 60 seconds return 504. Results use keyset pagination (follow the page.next URL / start cursor); higher limits can be requested from support.
  • SAP: Throttling is configured at the gateway and tenant level rather than as a single published rate limit.

How the Ramp and SAP connectors work

Ramp

Integration surface
REST API (Developer API v1)
Authentication
OAuth 2.0: exchange client_id/client_secret (HTTP Basic) at api.ramp.com/developer/v1/token for scoped bearer tokens; client_credentials grant for server-to-server and authorization_code for user-delegated access; scopes follow resource:permission (e.g. transactions:read, bills:write, accounting:write).
Change detection
Signed webhooks (HMAC-SHA256 X-Ramp-Signature) for bill, transaction, reimbursement, vendor, and user events; otherwise poll incrementally (synced_after on transactions, from_created_at on bills) with keyset pagination, or read the audit-logs/events feed.
