Salesforce Integration-Architect Exam With Confidence Using Practice Dumps

 The BatchApexErrorEvent object allows handling errors that occur during Batch Apex execution. By subscribing to this event,the integration can retry the invoice generation for the failed records or perform other recovery actions. This is a resilient and scalable solution that does not require custom code in the Batch Apex job itself or in the middleware1

The authentication is achieved by handling it in the code. A Named Credential is a type of metadata that specifies the URL of a calloutendpoint and its required authentication parameters. An Apex callout is a way to invoke anexternal web service or API from Apex code. When using a Named Credential with an Apex callout, the authentication is handled by the Apex code that invokes the callout. The Apex code can use the HttpRequest class to set the endpoint, method, headers, and body of the callout request, and use the Http class to send the request and receive the response. The Apex code can also use the NamedCredential class to access the properties of the Named Credential, such as the principal type, protocol, and credential type. Handling authentication with login flows is not a valid option because login flows are a way to customize the user login process in Salesforce, not for external web services or APIs. Connecting via Salesforce Connect or Communities is not a valid option because they are not related to Apex callouts or Named Credentials.

Create a special user solely for the integration purposes. This is the first thing that the Architect should do when building a solution that allows a service to access Salesforcethrough the API. Creating a special user for the integration purposes can help to ensure security, accountability, and traceability of the API calls. The special user should have a unique username, password, security token, and profile that grants only thenecessary permissions and access for the integration. The special user should also be assigned to an API-only user license type that prevents logging in to the Salesforce UI.
