# Achieve Data flow for E2E Testing

Effectively manage and reuse dynamic data extracted from API responses to streamline your API testing. Our tool allows you to store key-value pairs from API responses for subsequent use within the same test case or across multiple test cases of different technology.

In this section, you'll learn how to store the response value and re-use them along with some examples.

#### Storing Values

1. **Identify Target Data:** Determine the specific key-value pairs you want to extract from the API response and select the save option. 
2. **Store in Variable:** Assign the extracted value to a parameter for later use. You can also create a new parameter of type [runtime](/introduction-to-parameters/understanding-runtime-parameters.md) and assign.

#### Reusing Stored Values

After storing the required values from the API response, you can use the stored values as:

1. **Reference Variable:** In subsequent test steps or other test cases, reference the stored variable using its name.
2. **Dynamic Parameterisation:** Utilise variables to create dynamic test data and enhance test coverage.
3. **Cross-Test Case Dependency:** Pass values between test cases to simulate real-world scenarios.

To use the stored values, navigate to API editor and type '{{'. Select runtime parameter and choose the parameter in which the value is stored. [Learn more.](/introduction-to-test-management-in-simplifyqa/learn-api-testing/understanding-api-parameterisation.md)

Click on 'Send' to send the API request and get the response in the editor. 

By effectively utilising this feature, you can significantly improve the efficiency and reliability of your API test automation efforts.

# Agent Instructions: Querying This Documentation

If you need additional information that is not directly available in this page, you can query the documentation dynamically by asking a question.

Perform an HTTP GET request on the current page URL with the `ask` query parameter:

```
GET https://docs.simplifyqa.ai/introduction-to-test-management-in-simplifyqa/learn-api-testing/achieve-data-flow-for-e2e-testing.md?ask=<question>
```

The question should be specific, self-contained, and written in natural language.
The response will contain a direct answer to the question and relevant excerpts and sources from the documentation.

Use this mechanism when the answer is not explicitly present in the current page, you need clarification or additional context, or you want to retrieve related documentation sections.
