FDK Java

FDK client for Java language

Getting Started

Get started with the Java Development SDK for Fynd Platform

Usage

1. Create a new Maven project or use an existing one. Open the project's pom.xml file and add the following dependency to the <dependencies> section:

<dependency>
    <groupId>com.github.gofynd</groupId>
    <artifactId>fdk-client-java</artifactId>
    <version>1.4.14</version>
</dependency>

make sure to check the available version list on jitpack and use the appropriate version number.

2. Add the Jitpack repository to your project's pom.xml file. Place the following code snippet at the end of the <repositories> section:

<repositories>
    <repository>
        <id>jitpack.io</id>
        <url>https://jitpack.io</url>
    </repository>
</repositories>

3. Now you can start integrating the Java FDK Clients into your app. Below are two sample usage scenarios demonstrating how to use the ApplicationClient and PlatformClient classes.

---

Sample Usage - ApplicationClient

    ApplicationConfig applicationConfig = null;
    try {
          applicationConfig = new ApplicationConfig(
              "YOUR_APPLICATION_ID",
              "YOUR_APPLICATION_TOKEN"
              );
        if(Objects.nonNull(applicationConfig)) {
            ApplicationClient applicationClient = new ApplicationClient(applicationConfig);
            return applicationClient.catalog.getProductDetailBySlug("product-slug");
        }
    } catch (Exception e) {
        System.out.println(e.getMessage());
    }

Sample Usage - request function

The request function allows you to make custom API requests with ease. It is available on both platform and application client.

public Response request(String url, Map<String, String> queryParams, Map<String, String> headers, Object bodyObject, String method) throws IOException

Parameters

• url: A String representing the target URL for the HTTP request.
• queryParams: A Map<String, String> containing key-value pairs for the URL's query parameters.
• headers: A Map<String, String> representing any HTTP headers to include with the request.
• bodyObject: An Object representing the body of the request, typically used in POST, PUT, or PATCH requests.
• method: A String representing the HTTP method (e.g., "GET", "POST", "PUT", "PATCH" "DELETE").

Return Value

• Response: The method returns a okhttp3 Response object, which encapsulates the result of the HTTP request.

Example

import okhttp3.Response;
...
...
...

String url = "/service/platform/catalog/v1.0/company/1/products/";
String method = "GET";
Map<String, String> queryParams = new HashMap<>();
queryParams.put("company_id", "1");
queryParams.put("name", "black");
queryParams.put("page_no", "1");
queryParams.put("page_size", "10");
Response response = platformClient.request(url, queryParams , null , null, method);

if (response.isSuccessful()) {
    // Handle successful response
    String responseData = response.body().string();
    System.out.println(responseData);
} else {
    // Handle request errors
    System.err.println("Request failed with status code: " + response.code());
}


String urlPost = "/service/platform/logistics/v1.0/company/2/packaging-materials";
String methodPost = "POST";
Map<String, String> bodyMap = Map.of(
        "name", "Pack Big",
        "width", "24",
        "height", "24",
        "length", "24"
);
Response responsePost = platformClient.request(urlPost, null , null, bodyMap , methodPost);

---

Sample Usage - PlatformClient

    PlatformConfig platformConfig = null;
    try {
          platformConfig = new PlatformConfig(
          "COMPANY_ID",
          "API_KEY",
          "API_SECRET",
          "DOMAIN"
          );
        
        if(Objects.nonNull(platformConfig)) {
            PlatformClient platformClient = new PlatformClient(platformConfig); 
            
            // API's without application_id
            PlatformModels.OptinCompanyDetail companyDetail = platformClient.catalog.getCompanyDetail();
            System.out.println("Company Name : " + companyDetail.getName() );

            // API's with application_id
            PlatformClient.ApplicationClient applicationClient = platformClient.application("APPLICATION_ID");
            PlatformModels.GetCatalogConfigurationMetaData configurationData =  applicationClient.catalog.getCatalogConfiguration();
            return configurationData.getListing();
        }
    } catch (Exception e) {
        System.out.println(e.getMessage());
    }

Cookie

You can use persistentCookieStore from PlatformConfig or ApplicationConfig to read and write cookies.

Following code snippet will demonstrate how to use persistentCookieStore.

import java.net.CookieStore;
import java.net.HttpCookie;
import java.net.URI;

public class CookieExample {

    public static void main(String[] args) {

        try {
            ApplicationConfig applicationConfig = new ApplicationConfig("APPLICATION_ID", "APPLICATION_TOKEN");

            ApplicationClient applicationClient = new ApplicationClient(applicationConfig);

            // Accessing cookie store
            CookieStore cookieStore = applicationConfig.getPersistentCookieStore();

            // get cookies
            cookieStore.getCookies();

            // set cookies
            cookieStore.add(URI.create("https://api.fynd.com"), new HttpCookie("f.session", "<COOKIE>"));

            // remove cookies
            cookieStore.removeAll();
        }
    }
}

Cookies added to cookieStore will be automatically attached to subsequent requests. Also any request returning Set-Cookie headers will automatically added in the cookieStore.

Logging

To enable detailed logging of FDK in your Java project, set the log level for the SDK to DEBUG in the application.yml file:

logging.level.com.sdk: DEBUG

This setting provides comprehensive insights into Spring Boot operations and logs cURL commands for FDK-initiated requests.

---

Headers

When calling method, custom request headers can be included by passing a HashMap of headers in the method signature

Map<String, String> headers = new HashMap<>();
headers.put("x-api-version", "1.0");

ThemePlatformModels.AllAvailablePageSchema response = platformClient.application(applicationId).theme.getAllPages("<THEME_ID>", headers);
