Salesforce Integration Interview Questions with answers

1. What precisely does the terminology “integration” entail?

It is an elevated procedure involving two apps in which every organization is engaged in various applications. The majority of applications do not conform to the design requirements of ordinary businesses and do not synchronize with one another. As a result, there is a pressing need for the assimilation or integration of numerous apps to communicate with each other and assist businesses in attaining greater consistency and operational excellence levels. We will emphasize the total procedure of the accessible integration possibilities, which are strongly associated with other salesforce digital innovations. 

2. Describe the procedures for constructing integration.

The technique of integrating the user interface: It is essential in merging the different user interfaces on more than one software for the production of composite apps. There is no compelling reason to allocate tasks on the interface platform for any type of application.

The technique of Business Integration: This interconnection is appropriate in situations where a business flow requires coordination with numerous applications to conveniently execute hierarchical organizational processes. Apex callout is used for outward communication, and Apex internet services are used for incoming communication in this sort of connection.

Data integration technique – this approach uses the API and other tools that can efficiently manage the task of synchronizing datasets dataset and business needs. The most important techniques are also useful in coordinating one software with another. They take the shape of the main source, similar to the user inside the business object.

3. What exactly do you mean when you say “web services”?

Web Services are akin to the types of programming that let us accomplish the procedure of integrating apps. Web Services work similarly to open standard programs, particularly web-based programs, in that they can construct interactions between different web apps for data sharing. In addition, the use of web services like HTTP and XML has a functional advantage—transforming existing applications into web-based applications.

4. What does the expression “protocol” imply?

It is defined as a regulation and guidelines recognized and implemented to associate the two nodes of a communication system so that data can be handily shared. Moreover, it is fruitful in achieving shared approval of norms based on a set of parameters.

5. Talk about the many types of APIs accessible on the Salesforce platform.

For example, the rest of API is being used.

It’s useful for giving a handy framework for performing REST API-based Web Services so that it can effectively integrate with Salesforce. These are handy and straightforward to use, and they come with several benefits connected with smooth integration. The benefit of having a range of technology options when working on web-based tasks is significant. They’re even compatible with smartphone applications. One type of rest API, termed chatter API, can be used to create user interfaces for diverse regions, and there are other mass APIs for dealing with large amounts of data.

6. When and how should you use SOAP API?

They are quite beneficial in offering a straightforward framework for web-based services to interface with the Salesforce platform. You can conveniently change existing data and even create new ones. Another benefit of using this API is the ease of researching any language that supports web services. This allows the Salesforce platform to integrate various resource planning systems and other economic institutions to achieve real-time business operations.

7. What is the best way to use the Chatter REST API?

These are robust integration solutions for showcasing chatter bits and subscribers, and they’re ideally used on mobile apps. Use this API to give relevant applications access to the volume of data and suggestions so that notices and email alerts are easily accessible. This API is identical to the APIs that corporations provide to programmers and feeds such as Facebook and Twitter.

8. How can I make use of the streaming API?

This API is handy for obtaining real-time live feed admittance based on changes made to the recorded customized elements in Salesforce in the sequence they were made. If you would like to modify the files, the Salesforce platform will send out alerts whenever there are any alterations. In addition, the activity reports are issued for personalizing the alerts. Users receive the alerts due to pushing technology in the form of a system called CometD developed using the Bayeux protocol.

9. What is the difference between partner WSDL and enterprise WSDL?

  • Enterprise WSDL

It is inextricably linked to and associated with a specific kind of Salesforce platform. Therefore, if the fields are changed, they will adjust as well.

  • Partner WSDL

It is a weakly structured variable that is used to account for alterations to the interface. They are not flexible, thus are unable to implement adjustments to them even if the SalesForce structure changes.

10. How do you get access to SOAP?

WSDL documents are required to create a communication channel with this framework, and integration would be impossible without them. XML is the message format that is used.

11. Describe the various methods for generating the WSDL file.

To begin, go to Settings, then choose ‘develop,’ and lastly select ‘Apex Classes.’ After selecting the apex classes, you must press the build WSDL option. The ultimate step is to produce WSDL programming from the apex class and then save the record in the systems. Utilizing synchronizing datasets format.

12. What is the method of consuming the WSDL file?

Enter Apex Classes in the Quick Find box in the application, then choose Apex Classes from the Setup menu.

Next, select ‘Generate’ from WSDL from the drop-down menu.

To find a WSDL file on your local hard drive or system, click Explore/browse or type in the entire path. This WSDL file will serve as the foundation for the Apex class you’re building.

To validate the details of the WSDL file, click Parse WSDL. The application produces a default class name for each domain in the WSDL file and indicates any issues. For example, parsing fails if the WSDL comprises schema elements or constructions that Apex classes don’t allow or if the generated classes surpass Apex classes’ 1 million character count. 

Change the class names to your liking. You can save several WSDL namespaces into a single Apex class by utilizing the same class name for each; Apex classes are limited to 1 million characters in length.

Select ‘Generate Apex’ from the drop-down menu. The final page displays the classes that were generated successfully and any failures from other classes. A link to correctly created code is also provided on the page.

13. What’s the difference between SOAP and RESTful web services?

The Simple Object Access Protocol (SOAP) is an effort to establish a framework for developing web service APIs. A web service structure model lays out the fundamental guidelines to follow while creating web service technologies. However, HTTP is commonly used as a layer seven protocol; it is not required.

The SOAP message is made up of an enclosure that contains the SOAP header and body, which contains the data we want to transmit. It’s built on the industry-standard XML format, which was created specifically for transporting and storing structured data. SOAP can also refer to the XML format used by the envelope. Although SOAP is an established standard widely utilized in many systems, it does not use many of the features built into HTTP. While some people think it’s slow, it has many features that are necessary for many situations. Because of its unique format, it may currently be the best option for browser-based clients.

REST API: Representational State Transfer (REST) is a resource-based architectural approach that can be used instead of SOAP. Unlike SOAP, RESTful applications contain metadata in the form of HTTP built-in headers (with a range of media types) and conduct CRUD activities with the GET, POST, PUT, and DELETE verbs. 


We have gone over the Salesforce REST API interview questions, the significance of integration, and integrating Salesforce with other apps. These integration interview questions have assisted employees in understanding the various sorts of APIs present on the Salesforce platform and the variety of API usages based on the various business operations.
