How RocketHooks Works with SAP

RocketHooks connects to SAP systems through OData REST APIs exposed by SAP S/4HANA, SAP Business ByDesign, or the SAP API Business Hub. Monitor business-critical objects like purchase orders, materials, inventory, and financial documents without building custom ABAP programs or configuring SAP event mesh.

Compatible with SAP S/4HANA Cloud, SAP Business ByDesign, and any SAP system exposing OData services.

Authentication Setup

SAP typically uses basic authentication or OAuth 2.0 client credentials. For basic auth:

{
  "auth": {
    "type": "basic",
    "username": "YOUR_SAP_API_USER",
    "password": "YOUR_SAP_API_PASSWORD"
  }
}

For SAP S/4HANA Cloud with OAuth 2.0:

{
  "auth": {
    "type": "oauth2",
    "tokenUrl": "https://your-sap-instance.authentication.eu10.hana.ondemand.com/oauth/token",
    "clientId": "YOUR_CLIENT_ID",
    "clientSecret": "YOUR_CLIENT_SECRET",
    "grantType": "client_credentials"
  }
}

Endpoint Examples

Monitor Purchase Orders

Track new and modified purchase orders:

{
  "url": "https://your-sap-instance.com/sap/opu/odata/sap/API_PURCHASEORDER_PROCESS_SRV/A_PurchaseOrder?$top=20&$orderby=LastChangeDateTime desc&$select=PurchaseOrder,Supplier,PurchasingOrganization,PurchaseOrderDate,PurchasingDocumentDeletionCode",
  "method": "GET",
  "pollInterval": 120,
  "changeDetection": {
    "strategy": "jsonpath",
    "expression": "$.d.results[*].LastChangeDateTime"
  },
  "headers": {
    "Accept": "application/json"
  }
}

Monitor Material Master Changes

Detect updates to material records:

{
  "url": "https://your-sap-instance.com/sap/opu/odata/sap/API_PRODUCT_SRV/A_Product?$top=50&$orderby=LastChangeDateTime desc&$select=Product,ProductType,BaseUnit,LastChangeDateTime",
  "method": "GET",
  "pollInterval": 300,
  "changeDetection": {
    "strategy": "jsonpath",
    "expression": "$.d.results[*].LastChangeDateTime"
  },
  "headers": {
    "Accept": "application/json"
  }
}

Monitor Inventory Levels

Watch for stock level changes across plants:

{
  "url": "https://your-sap-instance.com/sap/opu/odata/sap/API_MATERIAL_STOCK_SRV/A_MatlStkInAcctMod?$top=100&$select=Material,Plant,MatlWrhsStkQtyInMatlBaseUnit",
  "method": "GET",
  "pollInterval": 600,
  "changeDetection": {
    "strategy": "deep-compare"
  },
  "headers": {
    "Accept": "application/json"
  }
}

Common Patterns

Procurement Automation

Monitor purchase order creation and approval status. When a PO is approved, trigger downstream workflows in your supply chain management system via webhooks.

Master Data Governance

Track changes to material, customer, and vendor master data. When critical fields are modified, alert the data governance team for review and approval.

Inventory Visibility

Poll SAP for inventory levels across multiple plants. Push real-time stock updates to your e-commerce platform or warehouse management system to prevent overselling.

Delivery Channels

Webhooks: Trigger ERP integration workflows or supply chain automation with HMAC-signed payloads and automatic retries

Additional delivery channels (Slack, email, SMS) coming soon.
