Definition
Integration Definitions is a Setup page for managing reusable integration configurations that define how Salesforce connects to external systems. These definitions encapsulate connection details, authentication methods, and data mapping rules that can be referenced by multiple integration processes.
Real-World Example
The developer at DataSync Corp creates an Integration Definition for their ERP system that specifies the REST endpoint, OAuth credentials via a Named Credential, and field mappings between Salesforce Order fields and the ERP's order schema. Multiple Flows and Apex classes reference this definition, so when the ERP endpoint changes, she updates it in one place.
Why Integration Definitions Matters
Integration Definitions is part of the Salesforce development ecosystem, which extends the platform beyond what is possible with declarative configuration alone. Developers use these tools to implement complex business logic, build custom user interfaces, and integrate Salesforce with external systems in ways that point-and-click tools cannot achieve.
The Salesforce development landscape operates within a multitenant architecture with governor limits, which means that understanding Integration Definitions is not just about knowing the syntax—it is about knowing how to build solutions that perform well at scale while respecting the shared infrastructure that all Salesforce customers rely on.
How Organizations Use Integration Definitions
- •Wonka Ltd — Their development team uses Integration Definitions to build custom integrations between Salesforce and their proprietary inventory management system. Real-time data synchronization means that sales reps always see accurate stock levels when quoting products to customers.
- •Dunder Mifflin Inc — Employed Integration Definitions to create a custom approval workflow that could not be achieved with declarative tools alone. The solution handles complex routing logic based on deal size, product line, and regional compliance requirements—all within Salesforce's governor limits.
- •Hooli Technologies — Leveraged Integration Definitions as part of their DevOps pipeline, using scratch orgs for feature development and continuous integration to catch issues before they reach production. This approach cut their deployment failures by 70% and shortened release cycles from monthly to weekly.
