Salesforce rarely works in isolation. Most Salesforce implementations rely on integrations to connect CRM data with external systems like ERPs, marketing platforms, payment gateways, data warehouses, and custom applications.
That leads to a very common question:
How many types of integration are there in Salesforce?
In this guide, you’ll get a clear, Salesforce-official breakdown of integration types, real-world examples, and best practices to help admins, architects, and ISVs choose the right approach.
Short Answer
There are five main types of integration in Salesforce: Data Integration, Process Integration, User Interface Integration, Business Logic Integration, and Security Integration.
Let’s explore each type in detail with examples.
Why Salesforce Integrations Matter
Salesforce integrations help organizations:
- Eliminate data silos
- Automate business processes
- Improve data accuracy
- Enable real-time decision making
- Scale enterprise systems
A strong integration strategy is essential for performance, security, and long-term scalability.
The 5 Types of Integration in Salesforce (Official Breakdown)
1. Data Integration
Purpose: Synchronize or move data between Salesforce and external systems.
Common Use Cases:
- Syncing customers from ERP to Salesforce
- Importing leads from marketing tools
- Exporting Salesforce data to data warehouses
Integration Methods:
- REST API
- SOAP API
- Bulk API
- Salesforce Connect
- ETL tools
Example: Syncing customer accounts from SAP into Salesforce nightly.
2. Process Integration
Purpose: Coordinate and automate business processes across multiple systems.
Common Use Cases:
- Order creation in ERP after opportunity close
- Triggering marketing workflows from Salesforce events
- Automating invoice generation
Integration Methods:
- Platform Events
- Change Data Capture (CDC)
- Flow + APIs
- Middleware orchestration
Example: When a deal closes in Salesforce, an order is automatically created in NetSuite.
3. User Interface (UI) Integration
Purpose: Provide a seamless user experience across Salesforce and external applications.
Common Use Cases:
- Embedding third-party apps inside Salesforce
- Displaying external data in Salesforce UI
- Launching Salesforce from another system
Integration Methods:
- Lightning Web Components
- Visualforce
- iFrames
- Canvas Apps
Example: Displaying a billing dashboard from an external system inside a Salesforce record page.
4. Business Logic Integration
Purpose: Share or centralize business logic between Salesforce and external systems.
Common Use Cases:
- Calling external pricing engines
- Running AI or ML models outside Salesforce
- Validating complex rules
Integration Methods:
- Apex callouts
- REST APIs
- External Services
- Middleware
Example: Salesforce calls an external fraud detection service before approving a deal.
5. Security Integration
Purpose: Ensure secure authentication, authorization, and access control.
Common Use Cases:
- Single Sign-On (SSO)
- Identity federation
- Secure API access
Integration Methods:
- OAuth 2.0
- SAML
- OpenID Connect
- Named Credentials
Example: Employees log into Salesforce using corporate identity providers like Okta or Azure AD.
Salesforce Integration Types Summary Table
| Integration Type | Purpose | Common Technologies |
|---|---|---|
| Data Integration | Sync data | REST, Bulk API, ETL |
| Process Integration | Automate workflows | Platform Events, Flow |
| UI Integration | Unified experience | LWC, Visualforce |
| Business Logic Integration | Share logic | Apex, APIs |
| Security Integration | Access control | OAuth, SAML |
Real-Time vs Batch Integrations in Salesforce
Salesforce integrations can also be categorized by timing:
Real-Time Integration
- Instant data exchange
- Used for user-driven actions
- Requires careful limit management
Batch Integration
- Scheduled or bulk data transfer
- Used for large data volumes
- More efficient for performance
Choosing the right timing is just as important as choosing the integration type.
Salesforce Integration Patterns
Beyond types, Salesforce architects use integration patterns such as:
- Request–Reply
- Fire and Forget
- Batch Data Synchronization
- Remote Process Invocation
Understanding these patterns helps design scalable integrations.
Best Practices for Salesforce Integrations
✔ Choose the right integration type ✔ Use Salesforce-native features first ✔ Avoid hardcoding credentials ✔ Monitor API usage ✔ Design for failure and retries ✔ Secure every integration
Common Salesforce Integration Mistakes
- Overusing real-time integrations
- Ignoring governor limits
- Mixing business logic across systems
- Skipping security reviews
- Not planning for scale
