Why teams connect Apollo.io and SAP S/4HANA

Close the gap between front office and back office: Apollo.io and SAP S/4HANA share customers and status in real time, in both directions.

Apollo.io holds the customer relationship; SAP S/4HANA runs the operations and records behind the business. The two overlap wherever the same organizations and transactions matter to both, and when that overlap is bridged by re-keying or overnight batch, each side spends the day working from stale data.

Stacksync syncs Deals (Opportunities), Tasks and calls, Custom fields, Contacts in Apollo.io with Sales Orders, Purchase Orders, Products / Materials, Billing Documents (Invoices) in SAP S/4HANA field by field, in real time, and in both directions. You decide which system owns which fields; Stacksync keeps every copy consistent and resolves conflicts by rules you set.

Common use cases

  • Land sequence enrollment status and outcomes in a warehouse for outbound performance reporting.
  • Deduplicate contacts across Apollo and the CRM by syncing on email as the match key.
  • Push closed-won CRM opportunities into S/4HANA as sales orders without manual re-keying.
  • Surface invoice and payment status from S/4HANA inside the CRM so account teams see open balances.

One customer master

Where both systems keep customer or organization records, corrections in either propagate to the other, ending dual maintenance.

Where SAP S/4HANA manages people and org data: keep Apollo.io aligned

Owners, territories, and org structure informed by SAP S/4HANA stay current in Apollo.io.

Where SAP S/4HANA handles order-to-cash: closed-won flows through

A deal won in Apollo.io creates or updates the customer in SAP S/4HANA with clean data, so fulfillment and invoicing start without re-entry.

What you can sync between Apollo.io 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.

Apollo.io objects SAP S/4HANA objects
Accounts Company records with firmographic attributes, matched to CRM accounts during sync. Billing Documents (Invoices) Invoice data pushed to CRMs and payment or collections tools for finance visibility.
People (database records) Prospects from Apollo's global database, pulled into downstream systems once enriched or saved. Deliveries Outbound delivery status synced to customer-facing systems for order tracking.
Sequences Outreach cadences (emailer campaigns in the API); enrollment status is read to track which contacts are being worked. Journal Entries Financial postings read into warehouses and consolidation tools for reporting.
Deals (Opportunities) Pipeline records that can be read and written to keep Apollo aligned with the CRM of record. Customer / Supplier Roles Role-specific views of Business Partners mapped to CRM account types.
Tasks and calls Rep activity records synced for activity reporting and coaching workflows. Production Orders Manufacturing order status surfaced in planning and operations tools.
Custom fields Account- and contact-level custom attributes mapped field-by-field in a sync. Business Partners Unified customer and supplier master records, the anchor entity for CRM-to-ERP account syncs.

Rate limits
Rate limits and enrichment credits vary by plan; bulk endpoints are throttled separately from single-record calls

SAP S/4HANA

Integration surface
OData REST APIs (v2/v4), with SOAP, BAPI/RFC, and IDoc interfaces on on-premise editions
Authentication
OAuth 2.0 with communication arrangements on cloud editions; basic auth or certificate-based on-premise
Change detection
Polling on change timestamps exposed by the OData services; business events can be emitted through SAP's event infrastructure on cloud editions
