To ensure the LWC displays all required transactions, the optimal approach is to use the Continuation class. This method allows asynchronous callouts to long-running services such as Enterprise APIs without blocking the execution of Apex code, thus improving performance and handling complex integration scenarios. It processes the response in a callback method, ensuring that the LWC displays up-to-date and comprehensive data. This approach avoids the pitfalls of making direct API calls from the LWC's JavaScript code, which is not considered a best practice due to security and efficiency concerns.

Salesforce Community Cloud must support both SAML SSO and Just-in-Time (JIT) provisioning to enable instant access for users the first time they log in, integrating with a SAML-based IAM system. Additionally, OpenId Connect Authentication Provider should be supported to accommodate users utilizing OpenId. Combining SAML SSO with JIT provisioning and OpenId Connect Authentication ensures seamless user experience with self-registration and single sign-on.

When deciding between Platform Events and Outbound Messaging for real-time or near-real-time needs, three key considerations should be evaluated. First, the number of concurrent subscribers to Platform Events is capped at 2,000, and Outbound Messaging configurations can send only up to 100 notifications in a single message to a SOAP endpoint. Second, both solutions offer declarative means for asynchronous near-real-time needs but are not best suited for real-time integrations. Finally, while both solutions are highly scalable, only Platform Events come with event delivery and event publishing limits that must be considered.

To expose data from on-premise applications to Salesforce in real time, two key actions are recommended. First, developing custom APIs on the company's network that are invokable by Salesforce will provide direct, real-time access to the necessary data. This approach allows Salesforce to make API calls to the on-premise systems when needed. Second, deploying MuleSoft to the on-premise network and designing external facing APIs to expose the data leverages MuleSoft's integration capabilities and security measures. MuleSoft can securely expose and manage the real-time data integrations between the two environments.

The company needs a way for customers to securely view their financial transactions without overwhelming Salesforce's data limits. Salesforce External Service can integrate directly with the core banking system, allowing for dynamic data display in real-time. This approach avoids the limitations of Salesforce Connect, which may have restrictions with the high volume of transactions. Additionally, this method maintains data security and access controls, which are critical for sensitive financial information.
