Salesforce APIs play a crucial role in integrating and extending the capabilities of the Salesforce platform. As organizations rely heavily on these APIs to exchange data and interact with Salesforce, ensuring their functionality, performance, and security becomes essential. That’s where Salesforce API testing comes into play.

In this blog post, we’ll explore various aspects of Salesforce API testing and how to harness the power of automation to make your API testing efforts more efficient and effective. Let’s get started.

What is Salesforce API Testing?

A Salesforce API is an alternative way for software testers to validate the application without using the User Interface (UI). It involves sending requests to API endpoints and checking the response’s performance, functionality, and security. This type of testing focuses on the application’s core business logic and performance rather than its visual appearance and user interface.

APIs are used whenever you want to connect an external application to Salesforce org. Salesforce supports different types of APIs like REST, SOAP, Metadata, Bulk, etc.

The different types of testing done to test these APIs are:

Functional Testing: This testing involves testing different API methods and verifying that they perform the intended operations correctly.

Integration Testing: This tests the integration between Salesforce and other external systems by verifying the seamless exchange of data and the correct functioning of interdependent APIs.

Security Testing – Verifies the security measures implemented in the APIs to protect sensitive data.

Performance Testing – Evaluates the performance of Salesforce APIs by measuring response times, throughput, and handling of concurrent requests.

Why Use Salesforce API Testing?


In DevOps, it is vital to “shift left,” which means you must test your application as early as possible to improve the product release product quality. API testing allows QA to access your application without a UI. This enables testers to identify issues even before the UI is created.

Increasing Test Speed

API tests are usually faster than UI tests, allowing more tests to be completed in less time. It helps improve your testing coverage, catching more defects before they go unnoticed. Also, it helps prevent bottlenecks in the software development process.

Easy Test Maintenance

The user interface of an application may vary slightly depending on the browser, platform, device, or screen orientation. Besides, the UI is often updated based on user feedback and behavior.

So, the QA must create and manage various UI test cases to cover these scenarios and changes. In contrast, Salesforce APIs are more stable, and any modifications are updated in detailed documentation, making it simpler for QA testers to maintain their test cases.

Why Should Salesforce API Testing Be Automated?

It is recommended to be automated for several compelling reasons, including:

Improved Accuracy

Manual testing can be very time-consuming and easily prone to mistakes, increasing the risk of defects going unnoticed till production. In contrast, automated Salesforce API testing is highly accurate and fast.

Also, it helps minimize the chances of defects slipping through and reaching production environments.

Time and Cost Savings

API testing is usually faster than UI testing, and automation can make the testing process even faster. It helps reduces the time needed to test new features, enabling quick software releases and cost savings in development.

Faster Feedback

Automated testing provides quick feedback to developers, helping them identify issues early. It reduces the time spent on debugging and enhances the overall product quality.

Increased Test Coverage

Manual Salesforce testing may not cover all the possible test scenarios. In contrast, automated testing provides broader test coverage. It helps identify edge cases, uncover hidden bugs, and ensure higher quality assurance.

Sample API Test Cases

Some sample Salesforce API test cases that validate the functionality and integration of Salesforce APIs:

  • Verify that the API endpoint requires valid authentication credentials (For example, OAuth token, API key).
  • Validate that the API rejects requests with invalid or expired authentication tokens.
  • Test different user roles and permissions to ensure proper access control.
  • Verify that the API endpoint returns the expected data when querying Salesforce objects (For example, accounts, contacts, and opportunities).
  • Verify that the API returns appropriate error responses (with proper HTTP status codes and error messages) when encountering invalid requests or server-side errors.
  • Test scenarios where required parameters are missing or have invalid values to ensure appropriate error handling.
  • Test API interactions with related objects and their dependencies to ensure data integrity and proper handling of relationships.
  • Verify that triggers, workflows, or other automation processes are correctly triggered when using the API.
  • Conduct load testing to evaluate the API’s performance under heavy concurrent usage.
  • Validate that sensitive data is properly encrypted and protected during transmission.
  • Test for potential security vulnerabilities, such as SQL injection or cross-site scripting (XSS), and verify that the API is protected against such attacks.
  • Verify that changes in API versions do not break existing integrations.
