How-To: Salesforce integration and REST API connection can enhance your Java application.

Maximize efficiency and drive growth with our tailored Java integration solutions, designed to elevate your Salesforce experience to new heights.

In 2024, businesses worldwide are leveraging Salesforce Integration Services to seamlessly connect Java applications with Salesforce’s robust data ecosystem. As a trusted Salesforce Consulting Partner, AwsQuality facilitates REST API integration, enabling efficient management of customer interactions and data manipulation. This integration empowers businesses to streamline operations, enhance user experiences, and drive corporate expansion.

Integrating Salesforce with Java enables you to create strong apps that easily communicate with Salesforce data. Salesforce is a potent platform for managing customer interactions. We’ll go over how to connect Java to Salesforce using the REST API in this tutorial. When you finish this course, you’ll have a working Java program that can search, add, edit, and remove Salesforce records.

Required conditions

Make sure you have the following setup before we start:

Java Development Environment Have you not installed Java on your machine yet?

Eclipse IDE (Optional): While any Java IDE will work, Eclipse is the most popular choice for Salesforce development.

JSON and HttpClient Libraries: In order to use Salesforce REST APIs, these libraries are required.

How to Connect Java to Salesforce

  1. Set up Java

Verify if Java is installed on your computer. Sure, here it is: You can find the download link on the official website.

  1. Configure Eclipse (Required)

Establish your workspace and start a new Java project if you’re using Eclipse.

  1. Set up the JSON and HTTPClient frameworks.

To handle JSON in your project and use HttpClient, download and include the required JAR files.

  1. Open Salesforce and Create a Connected App.

Open your Salesforce account and log in.

Go to Setup > Applications > App Manager.

Select “New Connected App.”

Enter the necessary information (callback URL, API settings, and app name).

Save the changes.

  1. Set up Java’s REST Environment

Configure your Java environment to respond to RESTful queries. This entails setting up authentication and constructing an HTTP client.

  1. Compose the Java application.

Let’s now write a Java application that executes transactions and establishes a connection with Salesforce:

import org.apache.http.impl.client.CloseableHttpClient; import org.apache.http.impl.client.HttpClients; import org.apache.http.client.methods.HttpGet; import org.apache.http.impl.client.HttpResponse;

class SalesforceIntegration, public {

public static void main (Args: String[]) { // Substitute with your Salesforce login information

“” is the string instanceUrl;

“your-access-token” is the string accessToken;

try (CloseableHttpClient httpClient = HttpClients.createDefault()) { // Example: Query Salesforce records HttpGet request = new HttpGet(instanceUrl + “/services/data/v52.0/query/?q=SELECT+Id,Name+FROM+Account”); request.setHeader(“Authorization”, “Bearer ” + accessToken);

Response from the HttpResponse is equal to httpClient.execute(request); // handle the response (process JSON, for example).

As an illustration, insert a fresh record.

As an illustration, update an existing record.

* Example: Delete a record * catch (Exception e) { * e.printStackTrace(); * } * } } catch (Exception e)

  1. Carry Out Transactions

You may connect to Salesforce, query data, and carry out additional tasks by running your Java program.


Salesforce and Java were connected using the REST API. Please feel free to investigate Salesforce’s other RESTful APIs for more sophisticated features.

Keep in mind that this guide only offers a broad overview.

Which typical use cases exist for Salesforce with Java integration?

Salesforce integration with Java provides a plethora of opportunities.
These are a few such usage cases:

  1. Syncing Contacts and Accounts:

Maintain contact information and your Salesforce account synchronized with other applications, including ERP (e.g., Oracle E-Business Suite or Netsuite). This guarantees current and consistent client data across all platforms.

  1. Possibility-to-Order Coordination:

Integrate Salesforce opportunities with your ERP system in a seamless manner. The integration makes sure that the right data is sent when an opportunity becomes an order.

  1. Employee Orientation:

Integrate Salesforce with your Human Capital Management (HCM) system to expedite the onboarding new employees. Using employee data from the HCM system, automatically establish user accounts, assign roles, and define permissions.

  1. User Engagement Within Apps:

Integrating Salesforce data into your Java apps will improve the user experience. One way to offer individualized experiences in your app is to show pertinent consumer data.

  1. Sales Funnel Administration:

Utilize Java to automate pipeline management, opportunity tracking, and lead conversion. Continually update your sales team about transactions and prospects.

  1. Customer Service:

    Connect Java apps to Salesforce Service Cloud to handle support tickets, cases, and customer questions. Address client concerns in a prompt, effective manner.

  2. Reporting and Analytics:

Java is used to retrieve Salesforce data and create customized dashboards and reports. Make data-driven decisions, track performance, and analyze trends.

  1. Integration of Marketing:

Link marketing automation tools to Salesforce. Measure ROI, monitor the success of campaigns, and automate lead nurturing.

  1. Working together and managing projects:

Connect Salesforce to project management software (like Jira) or collaboration platforms (like Slack). Maintain team cohesion and expedite project processes.

Keep in mind that there are countless options; these are just a few examples. The Java-Salesforce connection gives you the ability to streamline user experiences, automate tasks, and promote corporate expansion.

How can I migrate large amounts of data from Salesforce to Java?

Many factors need to be taken into account when transferring large amounts of data between Salesforce and Java. Let’s investigate a few strategies:

  1. Bulk API for Salesforce:

  • The large-scale data operations are the special purpose of the Salesforce Bulk API. It is perfect for data migration operations since it can handle records in bulk.
  • Salesforce records can be added, updated, upgraded, deleted, or queried using the Bulk API.
  • Here’s how you use Java to approach it:

Create a Client Application:

  • Install and configure your Java environment and programming platform (such as Eclipse).
  • Make use of the Salesforce Web Service Connector (WSC) toolset. By taking care of the fundamental functions and objects utilized in the Bulk API, WSC streamlines development.

Compose the Java code.

  • Make a Java application that communicates with the Bulk API.
  • To transmit and receive XML or JSON material, use the HTTP GET and POST protocols.
  • Obtain an authentication by means of OAuth or alternative techniques.
  • Execute bulk actions (updating, inserting, etc.) on Salesforce entries.

Carry out Transactions:

  • To move data in bulk, run your Java program.
  • Track developments and address any mistakes that may arise.
  1. Recognize Your Data:

  • Understand your data’s connections, structure, and dependencies in both your Java program and Salesforce extensively before transferring any data.
  • List any unique fields, objects, or other distinctive factors.
  1. Calculate the Impact on Performance:

  • Think about the amount of data you’re transferring. Performance may be affected by large datasets.
  • Make your Java code more efficient and deal with large amounts of data effectively.
  1. Design Information and Verification:

  • For your data migration procedure, define the metadata. Field mappings, transformation rules, and validation standards are all included in this.
  • Verify the accuracy of the data while migrating to prevent mistakes.
  1. Utilize Bulk API with Data Loader (Optional):

  • The Data Loader, which is available via Salesforce, may operate in bulk API mode.
  • Select the Bulk API mode in Data Loader or the normal REST API mode, depending on the operation and volume of data.
  1. Data Synchronization in Batch:

  • Think about dividing your migration into more manageable portions.
  • To ensure seamless data flow and prevent resource overload, use batch processing.

Keep in mind that data transfer is a crucial procedure that requires careful preparation and testing. Before executing your migration in production, test it in a sandbox setting.
