REST API - HTTP HEAD MethodThe HTTP HEAD method lets you submit a request and receive a response with the response body omitted. The purpose of the HEAD method is to save bandwidth if you do not require the response data that is usually included in the body.
what is GET api method
The GET method refers to a HyperText Transfer Protocol (HTTP) method that is applied while requesting information from a particular source. It is also used to get a specific variable derived from a group. The HTTP POST asks for input of information from the supplying browser into the server's message system.
what is POST api method
A POST method is used to send data to a server via API. It also creates subordinate resources, such as a file in a directory. REST Services are a folder that can hold any number of REST methods.
what is PUT api method
The PUT method updates an instance of a resource by replacing the existing resource with the resource provided in the request body. Configuration attributes that are set at the time a resource is created and that cannot be changed afterward are called immutable attributes.
what is PATCH api method
PATCH is used to apply partial updates to a resource, meaning that only the fields that need to be changed are sent in the request body. PUT is used to replace the entire resource with a new representation, meaning that all the fields of the resource are sent in the request body, even if they are not modified.
what is DELETE api method
The DELETE method is used to delete a specific resource in a REST API. It is performed by sending a DELETE request to the URL of the resource to be deleted, and the API will remove the resource if it exists.
what is OPTIONS api method
he Options API is a simple and standardized way of storing data in the database. The API makes it easy to create, access, update, and delete options. All the data is stored in the wp_options table under a given custom name. This page contains the technical documentation needed to use the Options API.

Technical & Coding based Questions and Answers
Q1: Explain the MVC Architecture in Salesforce.
In Salesforce, the MVC (Model-View-Controller) architecture is a prevalent design pattern. The Model element manages the data and underlying business logic, utilizing Salesforce’s database and objects. The View aspect is the interface seen by users, formed through Lightning components or Visualforce pages. The Controller part is responsible for processing user inputs and interactions, facilitated by Apex triggers and classes. This division of responsibilities boosts both the system’s modular nature and its ease of upkeep.
Q2: Describe the Difference Between Trigger and Workflow in Salesforce.
Salesforce utilizes both Triggers and Workflows for automation, though they have distinct functions. Triggers are segments of Apex code that execute around data operations, ideal for intricate business logic beyond the scope of declarative methods. Workflows automate certain actions like email sending or field updates, triggered by specific criteria and achieved without the need for programming.
Q3: How Do You Handle Bulk Data Operations in Salesforce?
To handle large-scale data operations in Salesforce, the Bulk API or Batch Apex is employed. The Bulk API facilitates the asynchronous loading or deletion of substantial data volumes, optimizing API utilization and time efficiency. Batch Apex processes extensive data by dividing it into smaller segments, effectively managing database operations and adhering to Salesforce’s governor limits.
Q4: What is SOQL and SOSL? How are they different?
Salesforce leverages SOQL (Salesforce Object Query Language) and SOSL (Salesforce Object Search Language) for data retrieval.

Have you done any batch Apex? Give me an e.g.: where you used batch Apex and just you say trigger?
ou don't call triggers directly anywhere. You perform a DML operation on sObjects, and the trigger will automatically fire. If your batch apex is performing DML (insert, update, delete, undelete) and you have an active trigger in the system for one of those events, the trigger will fire.
Can you elaborate little bit on writing test classes, importance of test classes, things you look for when developing a test class?
In Salesforce, a test class is a class that is used to test the functionality of another class, usually an Apex class, trigger, or web service. Test classes are written in Apex and are used to verify that the code written by developers works as intended before it is deployed to a production environment.
In Apex test class it’s really imp to have code coverage. What are some of other things imp when developing a test class?
Test class must start with @isTest annotation. Focus 90+ : To deploy to production at least 75% code coverage is required. But always try to focus on 90%+. We should not focus on the percentage of code coverage, We should make sure that every use case should covered including positive, negative,bulk and single record.
Within a visualforce page what is the first tag i.e. referenced in a visual force page? Can you tell me what that is?
Create the button called “ContactsForAccount” on Account Object and override above visualforce page with this button. Explination: Starting tag for a visualforcepage is <apex:page> and this follows standard object ACCOUNT. Forming a new page block which gives the user name and Account holder name.
When you define an Apex page, what are diff types of controllers that you can define, and differences bet them?
Types of Controllers in Salesforce
Standard Controllers:
Custom Controllers:
Controller Extensions:
Managing Data:
Automating Processes:

What is extensions class used for?
Note that the instance method that is defined in the extension class is used as an instance method on the augmented artifact. An extension method can access public and protected members only from the artifact that it augments. This behavior is by design.
Are you familiar with keyword “with sharing”? Give me an e.g. with and without?
if a method is defined in a class declared with with sharing is called by a class declared with without sharing, the method will execute with sharing rules enforced. If a class isn't declared as either with or without sharing, the current sharing rules remain in effect.
Case where you would want to have with sharing vs Apex triggers without sharing?
Use the with sharing keyword when declaring a class to enforce the sharing rules that apply to the current user and if you don't want to enforce it use without sharing keyword. We can use it in any type of classes build in apex.
With Apex triggers how would they usually execute it as? Will they take users sharing rules into consideration? Do they run Apex triggers in user context?
If your apex trigger is calling a class declared using “WITH SHARING”, then all sharing rules for the context user will apply during trigger execution. If your apex trigger is calling a class declared using “WITHOUT SHARING”, running under WITH SHARING context, the user's profile will come into play.
