Definition
Experience API is an application programming interface offered by Salesforce for programmatic access to platform capabilities. Developers use it to build integrations, automate data synchronization, and extend Salesforce functionality beyond the standard user interface.
Real-World Example
a CRM manager at Summit Group uses Experience API to centralize important business data in one place. With Experience API configured to match their workflow, the team can quickly find relevant information, track changes over time, and generate reports that drive strategic decisions.
Why Experience API Matters
Experience API (also called an Experience Layer API or XAPI in API-led connectivity) is an API designed specifically to serve the needs of a particular user experience, such as a mobile app, customer portal, or partner site. Rather than exposing raw Salesforce data, Experience APIs curate and aggregate data from multiple sources into the exact shape that the front-end application needs. This pattern reduces the number of API calls, simplifies front-end code, and allows the experience to evolve independently of the underlying data systems.
In mature Salesforce implementations, Experience APIs sit at the top of a three-tier API architecture (System, Process, Experience). Without this layer, front-end applications must make multiple calls to different back-end services and assemble the data themselves, leading to slow load times, complex client-side logic, and tight coupling between the UI and data sources. Organizations that implement Experience APIs gain the flexibility to redesign their user interfaces or launch new channels without rewriting back-end integrations.
How Organizations Use Experience API
- Summit Group — Summit Group builds an Experience API that aggregates Account details, recent Opportunities, open Cases, and the latest NPS score into a single response for their customer dashboard. The mobile app makes one API call instead of four separate calls, reducing page load time from 3 seconds to under 1 second.
- Catalyst Retail — Catalyst Retail creates different Experience APIs for their customer-facing app and their store associate app. Both consume the same underlying data, but the customer API returns simplified product and order information while the associate API includes inventory levels, markdown schedules, and customer loyalty tiers.
- Orbital Travel — Orbital Travel launches a partner booking portal and builds an Experience API that translates complex internal data models into a simple booking interface. Partners interact with a clean, documented API that hides the complexity of 6 back-end systems, and Orbital can upgrade those systems without breaking the partner experience.
