For implementing omni-channel selling with Revenue Cloud where customers can purchase directly from a third-party website and through sales reps, expertise in Salesforce Integration with REST APIs is essential. This integration skill enables the company to connect Revenue Cloud with external systems and third-party platforms.

Revenue Cloud is built on an API-first, modern architecture where every pricing, quoting, and revenue process is exposed via APIs. To enable direct purchases from a third-party ecommerce website while simultaneously processing sales rep transactions, the technical team must understand how to integrate external systems with Revenue Cloud through REST APIs. These APIs allow the website to communicate with Revenue Cloud, create quotes, submit orders, and manage the quote-to-cash process programmatically.

The omni-channel requirement specifically demands integration expertise because the company must synchronize data between its website platform and Revenue Cloud. APIs like Place Sales Transaction, Create Order, and Product Discovery APIs provide the technical foundation for this integration. Without strong integration skills including REST API knowledge, the company cannot effectively connect multiple sales channels to Revenue Cloud.

While Option B (Flows) are useful for automation within Salesforce and Option C (Apex/LWC) can enhance functionality, they are not the primary skill needed for external system integration. Flows are low-code/no-code tools suitable for internal process automation, and custom Apex/LWC are typically tertiary requirements. Integration expertise with REST APIs is the foundational skill that directly addresses the omni-channel architecture requirement.
