Businesses have found the need to integrate CRM platforms with their systems as a result of employing Salesforce CRM and utilizing its potential in their operations. The best method to stop this is Salesforce API integration, which will turn Salesforce into a full ecosystem where all business apps and processes coexist and operate independently while collaborating with one another.
After that, you might find yourself asking questions such as, “What exactly is an API in Salesforce?” How can I integrate Salesforce API? What does a Salesforce API developer do? Which API integration kinds are there? Well, you’re on the right page now.
This blog covers all aspects of Salesforce APIs, including how they operate, what types there are, how to create one, and more.
How does Salesforce define API?
First, let’s talk about Salesforce APIs.
Application Programme Interface (API) is the abbreviation for the Salesforce code or functionality that enables programmatic access to data in the Salesforce org environment in a straightforward and safe manner. In a nutshell, it links many apps and enables their collaboration.
Salesforce’s API Access Control allows you to restrict access to its APIs for all linked apps.
Let’s use an example to make things clearer.
Scenario 1: Absent Salesforce API Situation:
You successfully closed a profitable deal by utilizing Salesforce’s CRM capabilities in your business and other 3rd party inventory management tools. Then, you want to change your inventory to reflect the same.
The Things You Do
- To verify the order information and the sold goods, log into Salesforce manually.
- Keep a record of the product IDs, selling quantities, and customer information.
- manually log into the third-party inventory management system.
- Update the inventory levels and cut back on the sold-out product amounts.
- Finally, manually update the customer record with the revised inventory in Salesforce.
Problems You Face
Time-consuming in excess.
Hazards of manual error.
Difficulties with Salesforce and the inventory control system’s synchronization.
Multiple logins are required, and manual coordination between various departments is required.
Scenario 2: Using the Salesforce API Situation:
The Salesforce API enables seamless integration between Salesforce and the third-party applications you use for CRM and inventory management, respectively.
What You Do
- A contract is converted or closed in Salesforce.
- The third-party inventory management system receives a call automatically (through Salesforce AI).
- The inventory management system, on the other hand, receives the API call and immediately adjusts the inventory levels.
- A callback API to Salesforce refreshes the customer record with updated inventory after receiving an update from the inventory system.
fewer or no manual errors.
continuous updates in real-time.
Processes that are streamlined to save time.
simple handling of data consistency.
There is no requirement for manual departmental coordination.
While in the second case, the process was automated with the help of the Salesforce API, which saves time and enhances customer experience, the first scenario required manual intervention in several steps, which presented a number of difficulties and disadvantages.
Advantages of the Salesforce API
As we’ve stated, APIs help businesses access information or software potential from a different source, which results in greater value without requiring more expenditures of cash, time, or resources.
Efficiency and Automation
For more effective corporate processes, Salesforce API automates repetitive tasks like updating records, data entry, and workflows.
increased flexibility and personalization
Businesses may improve their Salesforce experience by using APIs, which provide them the freedom to adapt the platform to their own needs.
Improvements in Analytics and Reporting
You can create a comprehensive dataset that can be analyzed and published within the Salesforce environment through the integration of other systems, resulting in insightful business strategies.
The number and complexity of your business’s data increases as well. As a result, users can extend their operations without concern about manual data transfer limitations thanks to APIs, which handle this situation effortlessly.
Value for Money
By using APIs to automate company operations and data interchange, you can save money by reducing the time and labor required to complete these tasks manually.
Precision and Reliability of Data
The danger of human error—such as omissions or data duplication—is decreased with seamless connectivity between various systems, maintaining data consistency across platforms.
This, however, falls short of what Salesforce APIs can offer consumers, as shown below:
- Enhanced performance.
- Salesforce records can be retrieved, created, deleted, and updated.
- able to integrate Salesforce data with other enterprise platforms.
- between Salesforce and other programs, with no issues.
- Permit access to metadata.
- enhanced client experience.
- streamlined processes.
How Does Salesforce’s API Operate?
The following describes the Salesforce API’s fundamental workflow:
Before performing an API connection, the user first authenticates the external systems with Salesforce using OAuth flows or session IDs.
The external system sends an API request to Salesforce after authenticating, indicating which tasks, such as upgrading an opportunity or retrieving contact information, should be carried out.
Prior to processing the API request, Salesforce verifies the data, checks the data for validity, and performs the necessary tasks. The response is then ready.
When Salesforce responds to an external system, it frequently provides the data that was requested, confirmation that the request was processed successfully, or information about any issues.
Synchronisation of Data
Data can be synced between the external system and Salesforce in real-time or in stacks depending on the settings and API.
Simply said, the API acts as a link when two programs communicate with one another. One app uses APIs when it wishes to communicate with other apps, enhance the consumer experience, and utilize their assets (with permission).
By enabling corporations and third-party developers to utilize your technology in the most cutting-edge manner possible by becoming an API provider, you assist them in improving consumer experiences and streamlining internal procedures. You may avoid creating unique tools, modifying their data, and changing the page layout by using APIs.
Either a fundamental REST API or a SOAP API is used to construct the Salesforce API.
Now let’s discuss how Salesforce’s APIs function.
APIs are made by developers and provide access to resources that a business wants to share with others. These assets may include software, data, and brands used by partners, third-party services, or developers. Developers access resources via the built-in API by plugging in their apps and data.
In order to provide better experiences utilizing the data and services of other sites and apps, end users use apps and websites that take advantage of APIs.
Salesforce thinks about using an API-first strategy for developing features for its CRM platform. Users get the chance to take advantage of fantastic built-in features.
Salesforce takes APIs into consideration here, though, as businesses may require additional support to provide a reliable and ideal platform for every user. Salesforce customers use the APIs it offers to access all sorts of technology to build the capabilities their platforms require. This guarantees giving the platform’s users a better experience.
Salesforce’s API Types
Salesforce is strong in a variety of operations that enhance customer experiences. Similar to that, it offers developers a variety of integrations via APIs so they may use them to create practical apps.
Let’s look at the several APIs Salesforce has to offer.
APIs for rest
REST API, which stands for Representational State Transfer, is an architectural approach that uses HTTP methods like POST, GET, DELETE, and PUT to enable communication between two systems via the Internet. Based on RESTful principles, REST API is a powerful yet straightforward online service that displays all types of Salesforce capabilities using REST resources and HTTP protocols.
The underlying technology has no impact on REST APIs. Developers can therefore create client and server applications using a variety of programming languages without having an impact on the API architecture.
Writing mobile and online apps would benefit most from using the REST API, which supports both JSON and XML and has a lightweight request and response structure.
- Integration of Analytics
- Adaptation to Mobile Apps
- Development of bespoke software
- Integrated Web Application
- Including Third Parties
- Integrating and developing is simple.
- most suitable technology for usage in online projects and mobile applications.
How To Use:
- With other Salesforce REST APIs, REST API can be used for certain projects.
- constructing, altering, erasing, and reading records.
- Create UI for B2B commerce on Lightning, Experience Cloud sites, Chatter, or CMS-managed content using the Connect REST API.
Modern APIs are built on the Simple Object Access framework (SOAP API), a standardized messaging framework. Even before Apex became the primary programming language, there existed first the Salesforce API. This API precisely defines the parameters needed to access data using the API using a Web Services Description Language (WSDL) file. The only file types it supports are XML and JSON, and the majority of its features are also accessible via REST API. Depending on which best meets your company’s demands, you can use it. The WSDL file acts as a formal contract between the consumer and the API in SOAP, making it the finest API for creating server-to-server interactions.
WSDLs come in two varieties:
- Business Web Services WSDL
- For: Clients and independent software providers
- Goal: Create integration, especially for their Salesforce Org.
Due to its high level of security, SOAP API is seen to be ideal for handling sensitive data in applications like online banking and financial services.
Web Services WSDL for Partners
Regarding: Developmental Partners
To access data from any connected organizations, the goal is to create generic connectors for many Salesforce organizations.
- Data Migration with a Custom UI
- Adaptive Integration
- Unique Metadata
- Automated Custom Workflows
- It supports the SOQL and SOSL query languages, which can be used to obtain particular records or carry out sophisticated searches.
- The SOAP API enables Salesforce to be integrated with a variety of different systems, including CRM, ERP, and legacy systems.
- The best results may be obtained when retrieving metadata about files, objects, triggers, layouts, workflows, etc.
Why Use It:
You can add, update, retrieve, or remove records using SOAP API.
It aids in searching and is usable in any language that supports online services.
Salesforce developers utilize the simple-to-use bulk API to change a large amount of data with only one operation. You simply need to provide one command to complete any task involving your data, whether it be an edit, view, delete, or update. Bulk API guarantees parallel request processing while operating asynchronously. It is frequently utilized to transfer a lot of data.
- Post a large number of requests, then check the responses.
- transact with a lot of info.
- Fill your company’s system with data.
- Numerous records need to be updated.
- Complete tasks in an asynchronous manner, allowing you to send requests and receive results as they become available.
- In development environments, avoid storage restrictions when importing huge amounts of data.
Each batch of up to 10,000 records is processed by the bulk API in only 10 minutes.
- By enabling developers to process data in batches, each containing several records, it doesn’t tax the system’s resources.
- Bulk API helps developers find and handle mistakes ineffectively by holding the power to handle them.
- It allows parallel processing, allowing several batches to work simultaneously on the same job.
- Use it to asynchronously query, insert, query, upsert, remove, and update a large number of records.
- Utilizing the Bulk framework, you may plan, organize, and run an asynchronous workflow using any data activity with 2,000+ records.
Using the Pub/Sub API, it is possible to combine external systems with real-time systems. You have the option to subscribe to real-time events that result in data alteration. Users subscribe to channels that broadcast personalized notifications or data updates using the publish-subscribe, or pub/sub, model used by the APIs. Additionally, this strategy reduces API queries by obviating the requirement for often generating API requests in order to obtain data.
- Case Studies
- Keep a company’s Salesforce data up to date using information from outside sources.
- Permit users to handle the business logic of the external system when changing Salesforce data.
- Allow asynchronous communication between services with latencies.
- Events can be subscribed to and published in any order using the Sub API’s bi-directional streaming.
- Users can subscribe to streams of real-time events in Salesforce via the Pub/Sub API, which also helps connect real-time data to external systems.
- Peaks in buffer load and public traffic are reduced by this API’s subscription flow management.
- It creates a full API by combining all of the features.
- A custom CometD Streaming API client is not necessary thanks to the Pub/Sub API, which enables users to publish and subscribe to information about request topics, request topics, and events within a single API.
- With the help of this API, binary event messages can be delivered effectively in the Apache Avro format.
- Pub/Sub API is the ideal option when you need to integrate external systems with the events.
- For publishing and subscribing to event messages in Apache Avro format, this API is a preferable choice.
- You may take full advantage of the 11 programming languages that support gRPC with the help of this API.
REST API for analytics
The Analytics REST API, made available by Salesforce, is a web interface that helps client programs call services via HTTP protocols. Users are able to access Salesforce data without having to use the user interface. You can use this API to carry out operations, link Salesforce with your app, and use the Analytics REST API on any node that is hosting the analytics service. You can also use this API to get custom methods by coding it in Apex.
- Obtain data from the Dataset.
- Ask questions directly on the analytics platform.
- Incorporate fresh recipe nodes.
- Obtain data sets based on queries and creation dates.
- Apply the inclusive filter to the associated datasets.

- Send email notifications, start rapid actions, invoice Apex, and other standard and bespoke invocable activities.
- Obtain reports and dashboards, run reports, and update dashboards.
- Users may programmatically access Analytics assets like lenses, datasets, and dashboards thanks to the Analytics REST API.
- Additionally, you can send inquiries straight to the analytics platform.
- Make and collect lenses.
- The Analytics Platform has imported access datasets.
- Obtain XMD data and work with replicated datasets.
- Obtain a list of dataset versions.
- Make and get analytics applications.
- Create, modify, and get an analytics dashboard. Get the app’s list of dependencies.
- Identify the features that are offered to
The Metadata API
Salesforce organizations have the option of using the Salesforce Metadata API to create, deploy, delete, edit, or retrieve customized data. Custom page designs and definitions are part of this data. Metadata API can be used by developers to carry out these tasks. Every new update from the testing Sandbox environment into the active production environment is intended to be seamlessly migrated through the API. Businesses may create unique interactions, workflows, and apps by having access to metadata about Salesforce objects, fields, and other parts.
The 400 MB or 10,000+ files can be deployed and retrieved at once using the Metadata API.
Cases for Use
- Revise Visualforce pages
- Export customizations as XML files.
- Best for creating custom fields in a page layout
- Adjust existing modifications
- Developers can add, remove, and modify metadata components in a Salesforce environment using the Salesforce MetaData API.
- With the help of this API, programmers may keep track of changes made to the metadata component over time, facilitating version control and metadata configuration backups.
Why Use It:
- It supports the deployment, retrieval, creation, deletion, or upgrading of customizations for your company.
- Metadata API is frequently used to transfer changes from testing or a sandbox organization to your production environment.
- In addition to managing customization, it seeks to develop tools for managing the metadata model.
REST API Apex
The Apex REST API is a web service that lets programmers use Apex code to build REST-based web applications. This API exposes Apex via REST. Using this API, programmers can build unique endpoints for data access and bespoke logic execution.
The REST API and the Apex REST API differ primarily in that the Salesforce generic API is used. The latter is a custom API created by developers in Apex to provide custom methods.
- Apex REST API is used for CRUD operations including record creation, updating, deletion, and reading.
- It makes it easier to get information on a company’s restrictions.
- This API enables you to access reports and dashboards.
- Use the Apex REST API if you wish to call standard and bespoke invocable actions, such as sending email alerts and starting quick processes.
- This Salesforce API allows you to get and modify particular data, item metadata, and more.
Why Use It:
Apex REST API can be used to expose Apex classes and methods so that outside apps can use your code via REST architecture. Also supported for authentication are Session ID and OAuth.
SOAP Apex API
The Apex SOAP API, the initial option of a Salesforce API developer and architect, best shows the Salesforce Apex code and architecture through SOAP. In addition, using a few Apex classes and methods as web services to call other services or applications is made simpler by this API. You might select this API if you are still looking for a typical SOAP API to satisfy your integration requirements.
The finest record creation, update, deletion, and retrieval capabilities come from the APEX SOAP API.
This API allows you to do searches and retrieve the results from an external app.
This API enables simple messaging-based communication with the Salesforce platform.
Salesforce may be integrated with other systems like CRM, ERP, or legacy systems thanks to Apex SOAP API.
It is made easier for external applications to access the organization’s code via SOAP by exposing Apex methods as SOAP web services APIs with the aid of SOAP API.
OAuth 2.0 and Session ID are both supported for authentication with this API.
To build interactive tools and apps for Lightning Platform apps, developers use a software interface called the Salesforce Tooling API. Additionally, this API is preferable for retrieving metadata such as Apex classes, custom objects, triggers, and custom fields. Developers can use SOAP or REST to access tools API.
The former is more suited to straightforward migrations, which is how metadata API differs from tooling API. The latter provides developers with a platform for code coverage, debugging, auto-complete, and more.
- Make unique development tools, such as the developer console.
- Obtain the field’s metadata for an object.
- Obtain the metadata for both the default and custom object properties.
- Get metadata for Apex classes, custom fields, and triggers, among other things.
- Automate deployment by integrating with 3rd party technologies.
- Obtain information about the triggers and classes in Apex’s code coverage.
Why Use It:
- Custom development tools for the Platform apps can be made by Salesforce developers using the Tooling API.
- For particular services or applications, it creates specialized development tools.
- Small chunks of info can be retrieved with the aid of tools API’s SOQL features.
- Because smaller retrieves improve performance, tooling API is best suited for creating interactive apps.
A GraphQL API
The GraphQL API is a better option when you need to create scalable, responsive apps with just one request and return the data in accordance with the client’s requirements. This Salesforce API fetches data based on user access and is safe.
- Resource aggregation, field selection, and schema introspection can all be used to overcome the difficulties you encounter with conventional REST APIs.
- Reduce payload size by means of field choice and return just the fields expected to answer the inquiry.
- Through aggregations, GraphQL API minimizes round trips between the server and client and returns a cluster of pertinent resources as part of a single answer.
- Users are able to view the fields, objects, and types they have access to thanks to the schema introspection.
API for the user interface:
The Salesforce UI API is a set of tools used by Salesforce developers to build unique user interfaces for Salesforce apps. It has Apex controllers, Visualforce components, and a JS library. Additionally, the API creates unique Visualforce pages and Lightning components.
Make native mobile apps and customized web applications.
Recognize and respond to metadata alterations such as layouts, layout sharing, picklists, and field-level security.
provide data and metadata in one response.
Create user interfaces that make it simple for users to interact with records, activities, and more.
The User Interface API boosts productivity, efficiency, and smooth data flow.
Additionally, this API offers greater flexibility, scalability, and customer experience.
You can find the records independently in your UI without passing any queries when using the User Interface API.
Using the UI API that Salesforce utilizes to develop for the web, iOS, mobile web, and Android, you can design Salesforce UI for native apps and bespoke web applications.
Additionally, you may create user interfaces that assist users in working with actions, list views, bookmarks, records, etc.
All of the previously stated APIs—SOAP, Bulk, REST, and Pub/Sub—are widely used and together make up the Salesforce data APIs. These APIs are meant to be used to modify Salesforce data or to subscribe to data changes. The other APIs carry out a variety of tasks, such as developing unique development tools
