ABSTRACT
Nowadays Salesforce is one of the world’s leading customer relationship
management (CRM) programs.Ithelpstomanagecustomers,salesandservice
in one platform and salesforce provides manyautomationandreportingtools.
Salesforce Integration is the process of connecting Salesforce.com to other
3rd party external systems and applications like Facebook, LinkedIn, Gmail,
Outlook, Hub Soft, Heroku, SAP, Oracle, Microsoft, WordPress CMS and
external websites. The Salesforce API is as vast as deep blue sea because it
uses an API-first approach forbuildingfeaturesontheSalesforceplatform.API
first means to build a robust API before designing its UI. This approach
provides the flexibility to mold the data in whatever format required.
Appropriate Salesforce Integration allows enough access and also allows the
analysis of information. A Salesforce Integration solution is a software that
puts together and oversees correspondence between Salesforce CRM and
distinct frameworks, utilizingAPIstodecodemessagesthatsystemsexchange.
The decision of a Salesforce integration pattern depends upon the number of
frameworks to incorporate and their particulars, as well as the number of
integration levels to enfold.
A flawless Salesforce integration will helporganizationin thefollowingways–
Connects Marketing, Sales & Service with ERP, MRP, SRP and other back
office and legacy systems.
Gives a true 360-degree view of the customer across all systems.
Implement a multisystem end-to-end workflow over the systems.
Gives real time data access to come up with better sales and service
experience.
Strengthen the efficiency of process execution.

Remote Process Invocation - Request & Response
Request and Response pattern is beneficial for allowing data to be sent out to an external system to perform some functioning
and redirected back to Salesforce for it to be updated. This is to make sure that the data has successfully been retrieved and
processed on the other end but to get any response on which further processingcanoccurinSalesforce.TheSalesforceAPIwill
do the first callout while holding back on the external system to complete it before making progress.
External Services offers a Restful no code solution to send over primitive data typesto andfromtheExternal RESTAPIsusinga
lightning flow. When using a lightning component creating REST/SOAP calls or a custom Visualforce page with SOAP using
APEX Rest or SOAP. This allows the External Interface to bring in the APEX class and methods to perform REST/SOAP actions
on them. APEX Rest/SOAP permits writing out the classes togiveaccesstothe external systemtoconsumedata fromsalesforce
and use APEX HTTP callout to build a SOAP/REST call to the external API.
Remote Process Invocation - Fire and Forget
Fire and Forget is used when the sent request does not require waiting for a response. There are three DrivenPlatformEvents
that can be used since it allows the salesforce org to be either a subscriber or publisher of an event. This approach simplifies
the process by contributing both a no code and low code approach. There are two no code approaches. One is a Process –
Driven Platform Event utilizing a process builder to represent a Platform event. This can be done by utilizingthecreaterecord
action and selecting the Platform event as the record type. Workflow – Driven Platform Event uses a flow to publish the event
and has similar steps to bring out the event with a process builder. It uses the create record element and selects the platform
event as the record type. Customized –Driven Platform Event is thelesscodeapproachwhichisacquiredusinganApexClassto
bring out the event using the Event Bus class. Then once the event has been published the external applicationcansupportthe
event using CometD. Apart from using CometD the event can be subscribed from a Process Trigger, the pause Event in a
workflow, or an Apex Trigger. The next technique is Outbound Messaging and call backs which uses triggered workflows to
forward an outbound message to the external system when an insert or update happens. This allows the user to select the
object that has to be sent; define the endpoint and the fields from the object to be sent.
Batch Integration
The most common method of data integration which is appropriate for less frequently changing data. Itisaneffortlesswayfor
implementing and provides an excellent solution for processing flat files.
Remote Call – In
A remote system can create, retrieve, update, or delete data which is stored in Lightning Platform. When there is a remote
system which makes updates on Salesforce org a Remote Call-In pattern would be used. This allows the remoteAPI toconnect
to Salesforce which can make changes to the data that has changed and notify Salesforce of external events. Remote system
calls on Salesforce to either update or to query the data. It waits for successful completion & updates the response back in
Salesforce.
Remote systems is connected to Salesforce using the below methods:
Soap API
REST API
Apex Web Services
Apex REST Services
Bulk API
Data Virtualization
Data virtualization pattern is used when an external system performs operations that are nothandledbyorcarries data thatis
not present in Salesforce. This integration pattern allows users to use the Salesforce platform to acquire that data without
learning the external system. It allows for real-time access to the latest versionofinformationfroman external systemwithout
having to store the data in Salesforce.
POSSIBLE WAYS TO INTEGRATE WITH SALESFORCE
Data Integration
Data Integration uses SOAP APIs and REST APIs. It mostly handles data synchronization requirements, where one application
in an enterprise acts as the primary source for a particular business object, like Account. It requires no coding in Salesforce,
which is an advantage, but then it cannot implement any custom logic.

Data Integration is necessary when needed to sync data from two or more systems. As a result, every add-on that has been
integrated will share real-time data.
User Interface Integration
Salesforce allows designers and developers to create fascinating front-end User Interfaces (UI) for a much logical experience.
The front-end development is usually done through Visualforce and the Lightning Component Framework in Salesforce.
User Interface Integration combines the UIs of at least two frameworks. It gives users a single point of entry into many
applications. The most suitable example is Facebook Apps, which appears to be in the Facebook occurrence but in reality, the
content is served from different application traders.
Business Logic Integration
Business Logic Integration uses Apex Web Services for Inbound and Apex Callouts for Outbound. It typically handles cases
where business logic is built out across several applications to implement the complete end-to-end business process.
TYPES OF SALESFORCE INTEGRATION
Salesforce is the most flexible tool which offers ample ways to integrate data.
Real-Time Integration
Real-time integration is a high affinity to line up sales and marketing successfully. It is more suitable and less challenging to
handle errors and control queues.
App Exchange
There are several apps available in Salesforce which can be right away installed in the Salesforce environment. They are
necessary in reducing time and money in proper integration and hold up future enhancements.
Real-Time Mashups
It requires building-up of the user interface in Visualforce to create personalized UIs. They are commonly used for evaluating
the data from external systems quickly.
API INTEGRATION SOLUTIONS
The API Integration solutions gives access to developers to connect to the external API no matter the Protocol or Data Format
used. Below is the list of API Integration solutions that Salesforce offers:
REST API
REST stands for Representational state transfer. It is a
simple and strong web service built on restful principles. It
discloses all varieties of Salesforce functionality via REST
resources and HTTP methods. For example, one can create,
read, update, and delete (CRUD) records, search or query to
search data, retrieve object metadata, and access
information about limits in the org. REST API supports XML
and JSON both.
SOAP API
SOAP API stands for Simple Object Access Protocol API
which only supports XML.
It is a robust and strong web service built on the industry-
standard protocol of the same name. It can be utilized to
create, update, delete, retrieve records in any language that
supports web services. It is mainly used to maintain
passwords, perform searches, and retrieve metadata.
SOAP API supports XML only as it uses Web Services
Description Language (WSDL) files as a formal Contract
between API and consumer.
Bulk API
Bulk API is optimized to work with largevolumesofdata.Itis
used for querying, inserting, updating or deleting large
volumes of data. Allows to query or load large sets of data
programmatically. It is based on REST and executes
asynchronously.Bulk API supports attachment uploading. It
sends data in batches over HTTP.
Salesforce provides an interface to check the status of the
Bulk API job.
Metadata API
Salesforce metadata API is used by developers to retrieve,
create, deploy, update, or delete the customized data. The
purpose of Salesforce Metadata is to be used for
management to moldcustomizationsandbuildtoolstoassist
management at the mode of metadata. The easiest way to
acquire the functionality in Metadata API is to use the IDE of
Force.com or Ant migration tool.
Streaming API
Streaming API is the radar which allows todefineeventsand
push notifications to the client app when the event occurs.

No need to keep an active lookout for data changes or to
continuously poll Salesforce and create unnecessary API
requests.
Streaming API also keeps the external source in coincide
with the Salesforce data with PushTopic events and Change
Data Capture events. Italsoallowstheprocessingof business
logic in an external system in response to data changes in
Salesforce.
APEX SOAP
Apex SOAP web services gives access to an external
application to call Apex methods via SOAP Web services.
Apex callouts enable Apex to call external web or HTTP
services.
APEX REST
One can expose Apex classes and methods so that external
applications will be able to access code and applications via
the REST architecture. This is achieved by defining Apex
class with @RestResource notation to expose it as a REST
resource. Adding notation to methods can also expose them
through REST. For example, @HttpGet annotation can be
used for a method to expose it as a REST resource that can
be called by an HTTP GET request.
Tooling API
Tooling API is used to fetch the metadata like Apex classes,
Apex triggers, custom objects, custom fields, etc. If anyone
wants to get the list of Custom Objects or Custom fields,
there is no need to manually gather the details from the
whole SF organization. Instead, it can be gathered with the
help of Tooling API SOQL. Tooling API came in the Spring'13
release.
Chatter API
Chatter API is a REST API for Chatter to display Salesforce
information, especiallyinmobileapplications.Responses are
localized, structured for presenting, and can be filtered to
contain exactly what the application needs.
BENEFITS OF SALESFORCE INTEGRATION
Offers all-in-one access
Users don’t need to switch systems to get what they need.
They can stay logged into one system to get all done.
Increases productivity
Teams have to do a lot of cut-paste of data to make sure it
appears in all systems. However, manual tasks may lead to
mistakes and turn into a time consumer. Integrated systems
have automated checks and balances to makesuretheyhave
the same information.
Provides effortless access to data
System integration allows information to be acquired from
all the integrated systems. Having more information which
can convert into meaningful information, the more
information you have for making better decisions.
Enhances communication
One division may be more convenient with Salesforce while
another prefers to work with a different system. Integrating
these two systems will allow each team to work in the
system they prefer, which gracefully communicates and
leads to more data sharing.
Automates workflows without any code
Since integrated systems play well together,theirworkflows
can be automated with point-and-click.
Provides more insightful reporting
Users get more detailed and relevant reports that help them
to make better decisions and take the best actions.
CONCLUSION
Salesforce is an easy to learn and growing technology in the
market and all data is stored onto the cloud. The main
purpose of this review paper is to establish the basic
concepts of Salesforce Integration. Also for learning this
technology no one needs to have coding knowledge. Every
learning material is available on the internet and
Salesforce.com also has a free demo.
