Introduction

The Google Places API is a service able to return information about locations, using HTTP requests. Locations are defined internally to this API as as establishments, geographic locations, or prominent points of interest. It is possible to use the Google Places API with the most important programming languages. Google offers already implemented client libraries for Java, Javascript, Python, Objective-C and Go. It is however possible to use the Google Places API on every programming language supporting HTTP requests. This guide explains how to use Google Places API, properly configuring your Google account and creating an API key for it. In particular, here you will find:

  • How to properly set up a Google Cloud project to use the API
  • How to create an API key for your Google account to use the API
  • How to use the Google Places API with standard HTTP requests for every programming language

How to create an API key for Google Places API

Requirements to meet in order to be able to create a new API key to be used for Google Places API are the following:

  • A gmail or a Google Workspace account
  • A valid physical or virtual credit/debit card

A gmail or a Google Workspace account is needed in order to access your Google Developers Console, where you will be able to create a new API key. Google Places API will need your workspace project to be linked to a valid payment method to successfully process requests. Here are the detailed steps you are required to follow:

  • Access your Google Developer Console with your gmail or Google Workspace account
  • Create a new project, eventually linked to an organization in case you’ve been logging into a Google Workspace account
Step 1 - Creating a new Google Cloud Project
Enable "Places API" under the "Library" section

Enabling the Google Places API

Enable “Places API” under the “Library” section of the Google Developer Console. You will be required to create a new billing account or, eventually, to associate one, if already existing. You will be required to enter valid payment information, otherwise you won’t be able to correctly enable your API. Google won’t charge your payment method until you overcome the monthly $200 free threshold. You can get more information about API pricing at the Google Places Pricing page.

Creating an API key for Google Places

At this point, an API key should be automatically created. Copy down your API key and limit its usage to the “Places API”. If an API key isn’t created automatically, you will only have to go to the “Credentials” section of your Google Developer Console, then to create a new “API Key“. Whenever your API key is created, you should always apply restrictions to libraries able to use it.

Using OAuth2 for Google APIs: Creating Credentials

How to use OAuth2 for Google APIs

by Google APIs

What is OAuth2?

OAuth2 is a security protocol that allows applications to access user information without having to store their credentials. Authorization is managed through access tokens and granular permissions to ensure the security and privacy of users. Google uses OAuth2 to allow applications to securely access protected resources, such as user data or Google APIs. To start using OAuth2 with Google APIs, you need to register an application and obtain a client ID and a secret key. Afterwards, you can use Google’s client libraries to obtain a valid OAuth2 access token and use it to make requests to Google APIs. Client libraries are available in several programming languages including, but not limited to, Java, Python, C#, and JavaScript.

How to use OAuth2 to access Google APIs

To use Google APIs with OAuth2, the first step is to create a project in the Google Cloud Console and enable the desired APIs for your project. Next, you will need to create OAuth2 credentials for your project. If your project is a web application, you will need to provide a redirect URL to which the user will be sent after authentication. On the other hand, if the project is a server application, no redirect URL needs to be specified. The example below generates a Web API key in the Google Cloud Console and enables some Google libraries. In this example, we will use Google’s redirect URL to test authentication: https://developers.google.com/oauthplayground

Enabling Libraries to Use

To use Google’s client libraries with your application, you need to enable the corresponding library in the Google Cloud Console. Once you have logged in to the console, select your project and go to the “APIs & Services” section. Here you can search for the library you want to use and enable it. After enabling the library, you can download the client library for your preferred programming language and use it to integrate OAuth2 and access Google APIs. The example below shows the enabling procedure for the YouTube library.

Testing Libraries using Google OAuth Playground

Google OAuth Playground is a useful tool for testing Google’s client libraries and verifying that they are functioning properly. You can access Google OAuth Playground from the Google Cloud Console and use it to generate valid OAuth2 access tokens. This way, you can simulate the authorization and authentication process of your application and verify if the client library is functioning correctly. You can also test granular permissions by using Google OAuth Playground to selectively access Google APIs. The example below depicts testing YouTube APIs using previously generated credentials.
