NEW QUESTION # 51
Universal Containers ne=ds to integrate with several external systems. The process Is Initiated when a record Is created in Salesforce, The remote systems do not require Salesforce to wait for a response before continuing.
What is the recommended best solution to accomplish this?
Answer: A
Explanation:
The recommended best solution to accomplish the requirement is to use Outbound Messaging. Outbound Messaging is a way of sending notifications from Salesforce to an external system, using SOAP messages over HTTP or HTTPS. Outbound Messaging is triggered by a workflow rule, and can include up to 100 notifications per message. Outbound Messaging does not require Salesforce to wait for a response before continuing, as it uses the fire-and-forget pattern, which means that the message is sent and no acknowledgment is expected. Outbound Messaging also supports the guaranteed delivery of messages, as it uses a queue and a retry mechanism to resend the messages that are not delivered successfully. To use Outbound Messaging, the developer should create an outbound message action in the workflow rule, and specify the endpoint URL of the external system, the fields to include in the message, and the user to send as. The developer should also create a workflow rule that evaluates the criteria for sending the notification, and add the outbound message action to the rule. The external system should expose a SOAP web service that can receive and acknowledge the outbound messages. Using a PushTopic event would not be the best solution, as a PushTopic event is a type of Platform Event that represents a change in Salesforce data, such as a record creation, update, delete, or undelete. A PushTopic event can be subscribed by Apex triggers, flows, processes, Lightning web components, or external systems. However, a PushTopic event requires the external system to use the CometD protocol and the Streaming API to subscribe to the event channel, which may not be compatible with the external system's technology. A PushTopic event also does not guarantee the delivery of messages, as it uses the publish-and-subscribe pattern, which means that the message is sent and no acknowledgment is required. Using a trigger with HTTP callout would not be the best solution, as a trigger with HTTP callout is a way of invoking an external web service or API from Apex code, using HTTP or HTTPS requests. A trigger with HTTP callout requires Salesforce to wait for a response before continuing, as it uses the request-and-response pattern, which means that the request is sent and a response is expected. A trigger with HTTP callout also does not support the guaranteed delivery of messages, as it does not use a queue or a retry mechanism to resend the requests that are not delivered successfully. Using a Platform event would not be the best solution, as a Platform event is a type of Platform Event that represents a business event that occurs in the system, such as a change in data, a system error, or a user action. A Platform event can be published by Apex code, flows, processes, or APIs, and can be subscribed by Apex triggers, flows, processes, Lightning web components, or external systems. However, a Platform event requires the external system to use the CometD protocol and the Streaming API to subscribe to the event channel, which may not be compatible with the external system's technology. A Platform event also does not guarantee the delivery of messages, as it uses the publish-and-subscribe pattern, which means that the message is sent and no acknowledgment is required.
