The major modules within the Salesforce Communications Cloud include:

As the Spring '23 release for Salesforce is here, users are eagerly anticipating the new features and improvements that are in store. Here's a sneak peek at what you can expect from the upcoming release.

1. Improvements to Flow
1. Salesforce is making several enhancements to Flow in the Spring '23 release. You'll now be able to use variables in Flow to store record IDs, making it easier to reference specific records in your Flow. Additionally, Salesforce is making improvements to Flow Builder, making it more intuitive and easier to use.
2. Expanded Support for Einstein
1. Salesforce is continuing to invest in its AI technology, Einstein, and is introducing new features in the Spring '23 release. One of the most notable enhancements is expanded support for Einstein in the Sales Cloud. You'll now be able to use Einstein to score leads and opportunities, helping you to identify the most promising leads and close deals faster.
3. Improved App Development
1. Developers will be happy to know that Salesforce is introducing new tools to make app development easier in the Spring '23 release. One of the most exciting new features is the ability to use Lightning Web Components (LWC) in Visualforce pages, giving you greater flexibility in how you develop and design your apps.
4. Enhanced Security
1. As always, security is a top priority for Salesforce, and the Spring '23 release introduces several new security features. One of the most important is support for DMARC (Domain-based Message Authentication, Reporting & Conformance), which helps to prevent email spoofing and phishing attacks.
5. Revamped Setup Experience
1. Finally, Salesforce is giving its Setup experience a makeover in the Spring '23 release. The new Setup experience is more streamlined and intuitive, making it easier to navigate and find the settings you need.

These are just a few of the exciting new features and improvements that you can expect from the Spring '23 release. With each new release, Salesforce continues to evolve and improve its platform, making it more powerful and flexible for its users. Stay tuned for more updates and insights as the release approaches!

There are instances where einstein chat ends abruptly without any error message on the window. 

One such scenario I faced is: when an apex method is called from the bot.

There is an "@InvocableMethod" method which is called from dialog on Einstein Bot.

Even though the next step is set as "Start another dialog", the chat is getting closed without any error.

I realized that there is an option on the "Einstein Bot Builder" called "Performance".

This gives us the logs. In my scenario, the Apex class was not having access. 

Once the Apex class is added to "sfdc.chatbot.service.permset" permission set, it worked fine.

Currently, Salesforce is not allowing the creation or editing of LWC files on the developer console. To make simple changes to LWC files within salesforce without using Visual Studio Code.

Below are the steps I followed to create the component:

1. Created a connected app for using tooling API within the salesforce.
2. Created Named credentials with details from step 1.
3. Created Aura enabled methods in Apex class to get, create or update LWC components.
4. Created Future methods to overcome timeout error while making a call to tooling API.
5. Created LWC component to imperatively call apex methods from step 4 and edit or create the same source.

 Apex callout example:

Http http = new Http(); HttpRequest request = new HttpRequest(); request.setEndpoint('https://example.com'); request.setMethod('GET'); HttpResponse response = http.send(request); // If the request is successful, parse the JSON response. if (response.getStatusCode() == 200) { // Deserialize the JSON string into collections of primitive data types. Map<String, Object> results = (Map<String, Object>) JSON.deserializeUntyped(response.getBody()); // Cast the values in the 'animals' key as a list List<Object> animals = (List<Object>) results.get('animals'); System.debug('Received the following animals:'); for (Object animal: animals) { System.debug(animal); } }

Passing Parameters to REST callout:

Http http = new Http(); HttpRequest request = new HttpRequest(); request.setEndpoint('https://th-apex-http-callout.herokuapp.com/animals'); request.setMethod('POST'); request.setHeader('Content-Type', 'application/json;charset=UTF-8'); // Set the body as a JSON object request.setBody('{"name":"mighty moose"}'); HttpResponse response = http.send(request); // Parse the JSON response if (response.getStatusCode() != 201) { System.debug('The status code returned was not expected: ' + response.getStatusCode() + ' ' + response.getStatus()); } else { System.debug(response.getBody()); }

For Test class:

// Create the mock response based on a static resource StaticResourceCalloutMock mock = new StaticResourceCalloutMock();

// Associate the callout with a mock response Test.setMock(HttpCalloutMock.class, mock);

A callout example from trailhead:

@isTest global class AnimalsHttpCalloutMock implements HttpCalloutMock { // Implement this interface method global HTTPResponse respond(HTTPRequest request) { // Create a fake response HttpResponse response = new HttpResponse(); response.setHeader('Content-Type', 'application/json'); response.setBody('{"animals": ["majestic badger", "fluffy bunny", "scary bear", "chicken", "mighty moose"]}'); response.setStatusCode(200); return response; } }

Basic Authentication code:

String username = 'myname';

String password = 'mypwd';  

Blob headerValue = Blob.valueOf(username + ':' + password);

String authorizationHeader = 'BASIC ' +

EncodingUtil.base64Encode(headerValue);

request.setHeader('Authorization', authorizationHeader);

Authentication using Named credentials:

request.setEndpoint('callout:<Nameed credential>/services/data/v32.0');
