What is Google Maps API key?

Google Maps API key is used to access Google Maps API. Some applications or plugins using the capabilities of Google Maps require getting and adding an individual token. If you have one of these plugins, you should register on the Google API Console and get your own key.Google API key also allows for using capabilities offered by some services. Having an API key, you are given your individual free limit of user queries, according to your quota. This means your widget no longer has to share the usage limit with other widgets of the same origin and you may increase your limits if you need. Moreover, with Google Maps API key, you can monitor your queries and control them if necessary.

The key may be applied to any widget related to Google Maps API. All you need to do is copy-paste the key to the plugin dashboard. For example, Elfsight Google Maps plugin for WordPress has a special API key tab with the box, where you need to insert your key.

Secure your API key

After your key is created, it’s recommended to restrict it to prevent unauthorized usage. Please, go to Google Cloud Platform Console and click on your key. In the appeared form, select “HTTP referrers (websites)” and enter your site domain name in the field below. If you are an Elfsight Apps user, also add *.elfsight.com to be able to manage your widget from Elfsight Apps panel.

How do I handle my Google Maps usage limits?

When you get your Google Maps API key, you can set your daily quota for queries in the Google API console. Google Maps web APIs have 25,000 free requests per day, which means the service stays free during the day until you reach this number. If it is exceeded, you need to enable billing or buy a Premium Plan license to have a higher daily quota and allow for more queries.You can have more information concerning usage limits, higher quotas, billing and applying for increased limits on Google Maps API documentation page.

Using your key

So, getting your API key isn’t as difficult as it may sound, you need a couple of minutes and the work is done! We hope that our tutorial was helpful and now you can easily handle the task of having an API key. You can use your key in any Google Maps plugin, for example, Elfsight Google Maps widget is a perfect choice if you need a customizable map with various locations and option to create location lists. It allows to show maximum info about your business and has an automatic route calculation to attract more real-life visitors.

*An important note for Elfsight Google Maps users: make sure to add “apps.elfsight.com” and the name of the domain, where you are going to use the widget, to the domain field. The field can be found by choosing HTTP reference option in the Application Restrictions menu.

API security can be complex. In many cases, just because you’ve built an API that you want to make public, it doesn’t mean that you want just anybody accessing it. In most cases, you want fine-grained control over who can access the API, but setting up that kind of user management can be a daunting task: you’d have to create your own authorization service that can create API credentials for your users and have the ability to exchange those API credentials for an access token using OAuth 2.0. I’ve got good news! With just a few lines of code, Okta can handle all the complicated and time-consuming security elements and let you concentrate on creating a stellar API. =)

Understand the Basic Flow

When handling authentication for a server-to-server API, you really only have two options: HTTP basic auth or OAuth 2.0 client credentials.

Because OAuth 2.0 is the most popular way to secure API services like the one we’ll be building today (and the only one that uses token authentication), we’ll be using that.

With OAuth 2.0 client credentials, authenticating a client app is two-step process: first, the client sends its API credentials (a client ID and secret) to an authorization server that returns an access token. Second, the client sends a request to the API with that access token and the API verifies it and either authorizes the call or rejects it with a 401 Unauthorized response. In this tutorial, you’ll use Okta to manage your OAuth 2.0 server and rely on Okta’s default authorization server to create access tokens using API credentials (aka: client credentials) also created by Okta.

Install .NET Core 2.0

For this tutorial, you’ll be using version 2.0 of the .NET Core framework to create a .NET Core MVC application that will be the client, and a .NET core Web API that the client will call. To make sure you have .NET Core 2.0 installed, you can open a command window and run:

Ensure that you see 2.0.0 in the output. If you don’t, you can install it from here.

I will be running everything from Visual Studio Code, but it can easily be done from Visual Studio if you have access to that.

Create the API

In the folder where you want to keep source code, create a folder called webapi-okta-example and change into that directory.

Create a directory to hold the API project called api.

Create a directory in the webapi-okta-example folder to house the MVC app called app.

For development on the same machine, you’ll also need to tell the MVC app to run on another port, because the API will be running on port 5000. To do this, go to the Program.cs file in the MVC application and add the UseUrls() method, so that your BuildWebHost method looks like this:

Now, you should be able to fire them both up (with dotnet run from the command prompt, or just F5 in Visual Studio or Visual Studio Code) and see them both run independently.

Set Up the App in Okta

If you don’t already have an account with Okta, set up your free-forever developer account at https://developer.okta.com/signup/. Once you’ve logged into the dashboard, click on the Applications menu item, then click Add Application.

From the Create New Application screen choose Service, and click Next.

Name the application “API Sample App”, and click Done.

On the API Sample App’s general settings, you will see the Client Credentials box with the client ID and client secret in it. You will use these to authenticate a client wishing to call your API.

For each client that you’ll want to have access to the API, you’ll need to create an Okta application for it, and give it the Client ID and Client Secret.

Set Up Your App To Use Okta Client Credentials

In this case, the client of the API is the ASP.NET MVC application. Open the app folder in your IDE. Open the appsettings.Development.json file and add your Okta client information like so:

The TokenUrl property is the url to your default Authorization Server. You can find this in Okta by going to the dashboard and hovering over the API menu item in the menu bar, then choosing Authorization Servers from the drop down menu. The Issuer URI for the “default” server is the URI used for the TokenUrl property. The ClientId and ClientSecret properties are from the General Settings page of your API application in Okta.

In the “Models” folder of the application add a new class file called OktaSettings.cs. The contents of the class are:

This will allow you to read those configuration values into a C# object, making it easier to use in your application. To make it even easier, add this new object to the services that can be injected by adding it to the ConfigureServices() method in the Startup.cs file.

This will add the settings object as injectable IOptions into the constructor of any class that needs them. In this case, it will be an Okta-specific token service.

Create The Token Service

What you need here is a service that can live with the application lifecycle and either get a new access token, or return one that it already has. To do this, create an ITokenService interface and an OktaTokenService implementation class inside a new folder at the root of your MVC app called “Services”.

The ITokenService only needs one method: a method that returns an access token, call it GetToken().

The implementation will decide whether or not to get a new access token, or return one that it has previously received.

This first pass at the Okta token service starts by getting the oktaSettings injected from the application services. It also has a class-level variable that will hold the OktaToken object (which you’ll create in a moment). The GetToken() method merely checks to see if the token is valid and not expired (or expiring soon) and either gets a new access token, or just returns the current one.

Next, you’ll need to implement the OktaToken object. You can just nest it inside this class, since it will be the only consumer of this object. This will serve as a container for the response from the Authorization Service.

You’ll notice the JsonProperty attributes on several of the properties here. This is because, by default the JSON deserialize will match properties from camel-case (camelCase) to pascal-cased (PascalCase), but the properties returned in the token response are snake-cased (snake_case), so this tell the serializer what’s going on. Also, there is a IsValidAndNotExpiring, read-only property that ensures there is a value for the access token and that it is not expired, or expiring in the next 30 seconds. You can vary this value base on your use case.

You could just always make the API called and if it comes back with a 401 Unauthorized response, go and get a new access token then. The approach of checking to see if it’s expiring soon is simple and cuts down on failed calls in the logs.

Finally, the OktaTokenService class needs the GetNewAccessToken() method, in case it either doesn’t currently have an access token, or it is expired or expiring soon. This method will call your Authorization Server’s token endpoint to get a new access token.

A lot of this method is setting up the HttpClient to make the call to the Authorization Service. The interesting parts are the clientCreds value that gets the bytes of a string that has the client ID and secret concatenated with a colon between them as :. That value is then base64 encoded when it's added to the `Authorization` header with 'Basic ' in front of it. _Note that the word 'basic' is NOT encoded._

There are also two key-value pairs sent as FormUrlEncodedContent: the grant_type which has a value of “client_credentials”, and the scope which has a value of “access_token”. This simply tells the Authorization Server that you are sending client credentials and you want to get an access token in exchange.

The entire contents of the OktaTokenService(with using directives) should look like this:

Register the Token Service

To make the token service available to classes that need it, add another line to your ConfigureServices() method in Startup.cs so that it now looks like this.

Create an API Service

The token service will help you get an access token from the Authorization Server, but then you need to call the API with your newly minted token. Follow the same pattern as the token service by creating an IApiService interface and a SimpleApiService implementation class for it. The complete interface looks like:

This API service simply has a GetValues() method that will call the API and return a list of strings from the /api/values endpoint. The implementation class contains:

Again, much of this is setting up an HttpClient to make the API call (looks ripe for a refactor, but we’re okay for this demo). The real things of interest here are the AuthenticationHeaderValue with “Bearer” at the beginning and the access token. Also, the values returned from the API are deserialized into a list of strings to be returned.

As with the other services, add this to the ConfigureServices() method in Startup.cs, so that the final version of this method looks like:

Add the API Call to the MVC Application

Lastly for the client application, you’ll need to use the newly created services, in this case it will be in the HomeController.cs. Add the API service to the constructor, then just change the Index() action to return a Task<IActionResult> and call the API service to get the values.

Then you just need to display those values in the view. Remove everything from the Index.cshtml view except the carousel and add the values to the page right below the carousel.

Now you have the ASP.NET MVC application calling the API with a good access token every time.

The API is not receiving or doing anything to validate the access token yet, so your API is still “open”. All that is left to do is get the API to receive and validate the token!

Get the API to Validate the Access Token

There are two main ways to validate the access token: call the Okta API’s introspect endpoint, or validate the token locally. ASP.NET already has some JWT validation stuff built in. Calling the Okta API has the advantage of being very specific, and most secure way. It does have the disadvantage that you’ll need to make another API call. Using the local JWT validation built in to .NET means you don’t have to call the API, but is less secure. For the purposes of the demo, it’s secure enough, so you that here. In the ConfigureServices() method of the API project add the following before the services.AddMvc(); line.

The second service tells the app that you want to use JWT-based authentication and the options for the JwtBearer middleware gives the authentication scheme some information it can use to validate the token is authentic. The audience comes from the Authorization Server page in Okta.

Also, don’t forget to tell the application to use your new authentication set up. in the Configure() function add the line below just before the `app.UseMvc() line.

Finally, add the Authorize attribute to any controller or action you want to protect.

You can now run the API and try to hit it with a browser. You’ll see a screen that says the page isn’t working with an HTTP error of 401.

That’s it! If you run your app you will see the application displaying the values as before. You now have an API that is protected with access tokens provided by Okta, and only the worthy shall pass.
