Quick Start

Choose your development approach:

Scenario	Approach	API
Read/write employee data	OData V2 API	/odata/v2/ endpoints
Custom business objects	MDF (Metadata Framework)	MDF OData API
Event-driven extension	Intelligent Services	Event triggers → BTP
Analytics / reporting	People Analytics OData	$metadata reporting
UI extension	Extension Center	Custom UI on SF pages
Integration	SAP Integration Suite	Pre-built iFlows

Minimal API call — Get employee by ID:

GET https://<api-server>/odata/v2/User('EMPL001')
  ?$select=userId,firstName,lastName,email,department
  &$format=json
Authorization: Bearer <oauth_token>

Core Concepts

API Architecture

• OData V2: Primary API protocol for all SuccessFactors entities
• Entity sets: Map to business objects (User, EmpJob, EmpEmployment, PerPersonal, etc.)
• Compound Employee API: Single request for employee + all related entities
• Associations: Navigate between entities (User('ID')/directReports)
• Effective dating: Most HR entities have startDate/endDate for temporal data

Metadata Framework (MDF)

• Generic Objects (GOs): Custom business objects defined via MDF
• Rules engine: Business rules attached to MDF objects (onInit, onSave, onChange)
• Picklists: Reusable value lists for dropdowns
• Association types: 1:1, 1:N, configurable navigation
• MDF OData: Auto-generated OData endpoints for custom MDF objects

Permission Model (RBP)

• Role-Based Permissions (RBP): Foundation of SF security
• Permission roles: Group of permission grants assigned to users
• Target population: Which employees a role can access (granting rules)
• Permission groups: Logical grouping of entities and fields
• Field-level permissions: Control read/write/hidden per field per role

Integration Patterns

Pattern	Tool	When
Real-time sync	SAP Integration Suite iFlows	Employee master → S/4HANA
Event-driven	Intelligent Services → BTP	React to HR events
Batch extract	OData $filter with paging	Nightly data sync
UI mashup	Extension Center / BTP HTML5	Embed custom UI in SF

Common Patterns

Pattern 1: Compound Employee API (Efficient Bulk Read)

GET /odata/v2/CompoundEmployee
  ?$filter=lastModifiedDateTime gt datetime'2026-03-01T00:00:00'
  &$select=person/personIdExternal,
           personalInfo/firstName,personalInfo/lastName,
           jobInfo/company,jobInfo/department,jobInfo/jobTitle,
           employmentInfo/startDate
  &$format=json
  &$top=100
  &$skiptoken=<token_from_previous_response>

Pattern 2: Create Custom MDF Object Record

POST /odata/v2/upsert
Content-Type: application/json

{
  "__metadata": {
    "uri": "cust_Equipment('NEW001')"
  },
  "externalCode": "NEW001",
  "cust_name": "MacBook Pro 16",
  "cust_assignedTo": "EMPL001",
  "cust_status": "ASSIGNED",
  "effectiveStartDate": "/Date(1711929600000)/"
}

Pattern 3: Event-Driven Extension (Intelligent Services)

// BTP Cloud Foundry / Kyma — handle SF event
const express = require('express');
const app = express();

app.post('/sf-events', (req, res) => {
  const event = req.body;

  switch (event.type) {
    case 'HIRE':
      console.log(`New hire: ${event.userId}, start: ${event.startDate}`);
      // Trigger provisioning: AD account, equipment, onboarding tasks
      provisionNewHire(event.userId);
      break;
    case 'TERMINATION':
      console.log(`Termination: ${event.userId}, last day: ${event.endDate}`);
      // Trigger de-provisioning
      deprovisionEmployee(event.userId);
      break;
  }

  res.status(200).json({ status: 'processed' });
});

app.listen(process.env.PORT || 8080);

Pattern 4: OData Batch Request

POST /odata/v2/$batch HTTP/1.1
Content-Type: multipart/mixed; boundary=batch_001

--batch_001
Content-Type: application/http
Content-Transfer-Encoding: binary

GET User?$filter=department eq 'IT'&$select=userId,firstName,lastName&$top=50 HTTP/1.1
Accept: application/json

--batch_001
Content-Type: application/http
Content-Transfer-Encoding: binary

GET EmpJob?$filter=company eq '1010' and startDate ge datetime'2026-01-01T00:00:00'&$top=50 HTTP/1.1
Accept: application/json

--batch_001--

Pattern 5: OAuth2 SAML Bearer Token Flow

const axios = require('axios');
const { SignedXml } = require('xml-crypto');

async function getSFToken(userId) {
  // 1. Generate SAML assertion (signed with X.509 cert)
  const samlAssertion = generateSAMLAssertion(userId);

  // 2. Exchange SAML assertion for OAuth2 token
  const tokenResponse = await axios.post(
    'https://<api-server>/oauth/token',
    new URLSearchParams({
      grant_type: 'urn:ietf:params:oauth:grant-type:saml2-bearer',
      assertion: Buffer.from(samlAssertion).toString('base64'),
      client_id: '<api_key>',
      company_id: '<company_id>'
    }),
    { headers: { 'Content-Type': 'application/x-www-form-urlencoded' } }
  );

  return tokenResponse.data.access_token;
}

Pattern 6: People Analytics OData Report

GET /odata/v2/cust_headcountReport
  ?$filter=asOfDate eq datetime'2026-03-24T00:00:00'
  &$select=department,headcount,fte,avgTenure
  &$orderby=department asc
  &$format=json

Error Catalog

HTTP Status	Error	Root Cause	Fix
401	Invalid OAuth token	Token expired or wrong API server	Refresh token; verify token URL matches API server region
403	Insufficient permissions	RBP role missing for entity/field	Check Admin Center → Manage Permission Roles; add entity permissions
400	Invalid effective date	Date format wrong or future-dated insert blocked	Use /Date(epoch)/ format; check date restrictions on entity
404	Entity not found	Wrong entity name or entity not enabled	Check $metadata; some entities need activation in Provisioning
429	Rate limit exceeded	Too many API calls per minute	Implement exponential backoff; use $batch for bulk operations
500	Business rule validation failed	MDF rule rejected the data	Check Manage Business Rules for the object; review rule conditions

Performance Tips

1. Use $select — Always specify needed fields; SF returns ALL fields by default (very slow)
2. Compound Employee API — One call vs. 5-10 separate entity calls per employee
3. $batch requests — Group up to 100 operations in one HTTP call; reduces round-trips
4. Paging with $skiptoken — Never use $skip for large datasets; use server-driven paging
5. lastModifiedDateTime filter — Delta sync instead of full extract
6. Cache $metadata — Metadata response is large (>1 MB); cache it, refresh daily
7. Avoid deep expansions — $expand with 3+ levels causes timeouts; use separate queries
8. Time zone awareness — All dates in UTC; convert at display layer, not in API queries

Gotchas

• Effective dating: Every update to EmpJob, EmpEmployment, etc. requires startDate; omitting it creates records effective "today" which may conflict with existing records
• Picklist values: Use picklistId + optionId, NOT display text — display text is locale-dependent
• API server vs. data center: Token endpoint and API base URL may be different hostnames
• SAML assertion clock skew: Assertions must have NotBefore / NotOnOrAfter within 5 min of server time
• MDF field limits: Custom MDF objects max 150 fields; plan field usage carefully
• Integration Center vs. Suite: Integration Center (within SF) for simple scenarios; SAP Integration Suite for complex multi-system flows

Advanced Patterns

Extension Center — Custom UI Injection

// SF Extension Center: inject custom UI into SuccessFactors pages
// Hosted on BTP HTML5 Application Repository
// Registered via Admin Center → Extension Center

// manifest.json (Fiori-style)
{
  "sap.app": {
    "id": "com.company.sf.custom-onboarding",
    "type": "application",
    "applicationVersion": { "version": "1.0.0" }
  },
  "sap.sf.extension": {
    "targetPage": "EmployeeProfile",
    "position": "belowHeader",
    "label": "Custom Onboarding Checklist"
  }
}

Employee Central → S/4HANA Replication

SF Employee Central               SAP S/4HANA
     │                                 │
     ├─ Employee master data ─────────►│ Business Partner (BP)
     │  (HCM replication)              │
     ├─ Org structure ────────────────►│ Org Management
     │                                 │
     ├─ Cost center assignment ───────►│ CO cost centers
     │                                 │
     └─ Compensation data ────────────►│ Payroll (optional)

Replication setup:

1. Enable API Center in SF (Admin Center → Company Settings)
2. Configure Integration Center for employee replication
3. Map SF fields to S/4HANA BP fields
4. Set up delta sync (lastModifiedDateTime filter)

MDF Business Rules Engine

Rule Type: onChange
Object: cust_LeaveRequest
Trigger Field: cust_leaveType

IF cust_leaveType == "ANNUAL"
  THEN SET cust_requiresApproval = TRUE
  AND SET cust_maxDays = 30

IF cust_leaveType == "SICK"
  AND cust_days > 3
  THEN SET cust_requiresMedicalCert = TRUE

IF cust_startDate < TODAY()
  THEN RAISE ERROR "Leave start date cannot be in the past"
