CTS client libraries

This page shows how to get started with the Cloud Client Libraries for the Cloud Talent Solution API. Client libraries make it easier to access Google Cloud Platform APIs from a supported language. Although you can use Google Cloud Platform APIs directly by making raw requests to the server, client libraries provide simplifications that significantly reduce the amount of code you need to write.

Read more about the Cloud Client Libraries and the older Google API Client Libraries in Client libraries explained.

Client libraries for more languages are coming soon.

Install the client library

C#

If you are using Visual Studio 2017 or higher, open nuget package manager window and type the following:

Install-Package Google.Apis

If you are using .NET Core command-line interface tools to install your dependencies, run the following command:

dotnet add package Google.Apis

For more information, see Setting Up a C# Development Environment.

Go

go get google.golang.org/api/jobs/v3

For more information, see Setting Up a Go Development Environment.

Java

If you are using Maven, add this to your pom.xml file:

<dependency>
    <groupId>com.google.apis</groupId>
    <artifactId>google-api-services-jobs</artifactId>
    <version>LATEST</version>
</dependency>

For more information, see Setting Up a Java Development Environment.

Node.js

npm install --save googleapis

For more information, see Setting Up a Node.js Development Environment.

PHP

composer require google/apiclient

For more information, see Using PHP on Google Cloud.

Python

pip install --upgrade google-api-python-client

For more information, see Setting Up a Python Development Environment.

Ruby

gem install google-api-client

For more information, see Setting Up a Ruby Development Environment.

Set up authentication

To authenticate calls to Google Cloud Platform APIs, client libraries support Application Default Credentials (ADC); the libraries look for credentials in a set of defined locations and use those credentials to authenticate requests to the API. With ADC, you can make credentials available to your application in a variety of environments, such as local development or production, without needing to modify your application code.

For production environments, the way you set up ADC depends on the service and context. For more information, see Set up Application Default Credentials.

For a local development environment, you can set up ADC with the credentials that are associated with your Google Account:

Install the Google Cloud CLI, then initialize it by running the following command:
```
gcloud init
```
If you're using a local shell, then create local authentication credentials for your user account:
```
gcloud auth application-default login
```
You don't need to do this if you're using Cloud Shell.

A sign-in screen appears. After you sign in, your credentials are stored in the local credential file used by ADC.

Use the client library

The following example shows how to use the client library.

Go


// Command quickstart is an example of using the Google Cloud Talent Solution API.
package main

import (
	"context"
	"fmt"
	"log"
	"os"

	"golang.org/x/oauth2/google"
	talent "google.golang.org/api/jobs/v3"
)

func main() {
	projectID := os.Getenv("GOOGLE_CLOUD_PROJECT")
	parent := fmt.Sprintf("projects/%s", projectID)

	// Authorize the client using Application Default Credentials.
	// See https://g.co/dv/identity/protocols/application-default-credentials
	ctx := context.Background()
	client, err := google.DefaultClient(ctx, talent.CloudPlatformScope)
	if err != nil {
		log.Fatal(err)
	}

	// Create the jobs service client.
	ctsService, err := talent.New(client)
	if err != nil {
		log.Fatal(err)
	}

	// Make the RPC call.
	response, err := ctsService.Projects.Companies.List(parent).Do()
	if err != nil {
		log.Fatalf("Failed to list Companies: %v", err)
	}

	// Print the request id.
	fmt.Printf("Request ID: %q\n", response.Metadata.RequestId)

	// Print the returned companies.
	for _, company := range response.Companies {
		fmt.Printf("Company: %q\n", company.Name)
	}
}

Java

        .createScoped(Collections.singleton(CloudTalentSolutionScopes.JOBS));
  } catch (Exception e) {

      }
    }
  } catch (IOException e) {
