When dealing with high-volume data (1 million transactions per day) that does not need to be stored natively in Salesforce, the architect should recommend Data Virtualization via Salesforce Connect.

Salesforce Connect allows the company to display external data as External Objects. This approach provides several architectural advantages for a banking community:

No Data Storage: Transactions remain in the core banking system, avoiding the massive storage costs and complex synchronization logic required to house millions of records natively in Salesforce.

Real-Time Visibility: Because External Objects are queried on-demand via the OData protocol or a custom Apex adapter, customers see the most up-to-date transaction history every time they refresh the page.

While an Iframe (Option B) is technically possible, it is often discouraged due to security concerns (such as clickjacking) and a poor user experience, as the Iframe does not natively integrate with Salesforce UI components or reporting. Salesforce Connect provides a 'seamless' look and feel, allowing External Objects to be used in related lists and Lightning components just like standard Salesforce records, while keeping the heavy data burden on the performant core banking system.

This scenario describes a classic Request and Reply pattern where a user action in the UI requires an immediate, synchronous response from an external system to determine the next step in a business process (the Flow).

The requirement specifies that an OpenAPI 2.0 (Swagger) definition is available. For an Integration Architect, this is a prime use case for External Services. External Services allow you to import an OpenAPI schema and automatically generate 'Invocable Actions' that can be used directly in Flow Builder without writing a single line of Apex code.

Why this is the best fit:

Low Code: It fulfills the requirement purely through declarative configuration, which reduces maintenance and development costs.

Real-Time: It performs a synchronous HTTP callout and waits for the Boolean/String values to be returned to the Flow variables.

Type Safety: Because it uses the OpenAPI definition, Salesforce understands the data types (Boolean/String) natively.

Option A (Data Virtualization) is more suitable for viewing and searching large external datasets as if they were records; it is over-engineered for a simple 'check status' function. Option C (Remote Call-In) is the inverse of the requirement; it refers to an external system calling into Salesforce. By using Enhanced External Services, the architect provides a scalable, declarative solution that perfectly aligns with modern Salesforce development best practices for real-time external system interaction.

To securely integrate a distributed package with a central 'Hub' org, the architect should utilize the OAuth 2.0 Web Server Flow. In this model, a Connected App is created in the central org to act as the identity and access provider.1

A critical component of this setup is the Callback URL (Redirect URI). When a user in the 'Subscriber' org (where the packag2e is installed) initiates the connection, Salesforce redirects them to the central org to authorize the access. After successful authentication, the central org needs the correct callback URL to return the authorization code to the specific subscriber org.

Using this flow satisfies the security team's requirement for a specific integration account. The administrator in the central org can pre-authorize specific profiles or permission sets to use the Connected App, ensuring that only the designated integration user's credentials are used to fulfill requests. Option A is a security 'anti-pattern' (storing passwords in fields), and Option C is unnecessary as API access is a standard feature. This OAuth-based approach provides a secure, revocable, and standardized way to manage cross-org communication in a multi-tenant environment.

The foundational step in a CRM transformation project is to understand the business context and data landscape before selecting technical tools or middleware.

Before proposing a technical solution, an architect must evaluate current and future data and system usage to identify specific integration requirements. This includes documenting business processes, mapping data flows between the Marketing system, Outlook, and the ERP, and identifying which system will serve as the 'System of Record' for each data entity. For example, the architect needs to determine if lead data from the Marketing system should flow unidirectionally to Salesforce or if activities from Outlook need bidirectional synchronization to maintain a '360-degree view'.

While out-of-the-box connectors (Option B) and middleware (Option C) are valuable, they are implementation tactics that follow the discovery phase. Jumping directly to connectors may overlook unique business processes that require custom integration logic, while proposing middleware prematurely can lead to unnecessary costs if native tools or point-to-point connections are sufficient. A thorough evaluation ensures that the integration architecture is scalable, avoids data corruption, and aligns with UC's strategic goal of breaking down information silos to provide sales and support staff with meaningful, unified customer insights.
