April 24, 2024 - For example, the Google Maps API key contains information that allows developers to access the functionality of the API to integrate it with their application without the end user needing to access Google Maps separately.

In OpenAPI 3.0, API keys are described as follows: ... This example defines an API key named X-API-Key sent as a request header X-API-Key: <key>. The key name ApiKeyAuth is an arbitrary name for the security scheme (not to be confused with the API key name, which is specified by the name key).

The following table shows randomly generated examples of secret and publishable keys: Anyone can use your live mode secret key to make an API call on behalf of your account, such as creating a charge or performing a refund.

November 10, 2023 - A popular method for early APIs, passing an API key through a query string in a URL is certainly easy. However, this method can risk API key exposure since, despite encryption, the parameters can be stored in web server logs. curl -X GET "https://example.com/endpoint/?api_key=abcdef12345"

These keys allow builders and businesses to maintain control and monitor access over services and ensure security. In this post, well further explain what API keys are, what they're used for, the types of API keys, and how to generate an API key.

February 3, 2021 - If that code contains an API key, then anyone who reads the question can see and use the key! One solution is to put the key into a property file. An obvious, but very poor choice would be to put it into the Info.plist file. This is a poor choice because Info.plist will almost certainly get checked into a repository, which may be public. A better option is to create a separate property file, in our example Weather/Open-WeatheMap-Info.plist:

They are commonly used on Internet-of-Things (IoT) applications and websites to gather and process data or enable users to input information. For example, users can get a Google API key or YouTube API keys, which are accessible through an API ...

The API key string is an encrypted string, for example, AIzaSyDaGmWKa4JsXZ-HjGw7ISLn_3namBGewQe. When you use an API key to access an API, you always use the key's string.

This will often require your application to accept user input, so you'll want to create variables that can hold this input after the user has submitted it. In this example, we'll create an API call using the Current Weather Data portion of the OpenWeather API, and we'll search by city name.

APIs serve to let different software modules communicate with each other — a process which typically entails a transfer of data or functionality. The Google Maps platform, for example, uses API keys to enable requests for map data from other ...

For initial testing, you can hard code an API key, but this should only be temporary since it's not secure. You can find examples for hard coding the API key in Providing API key explicitly section.

Paste the API key access token into your application. Your application uses the API key as an access token to access secure resources.

When dealing with APIs, you may encounter something called an API key. They’re sort of like passwords which let APIs confirm your identity. Once an API knows you’re legitimate, you can get through and use the API’s full set of features. Example of an API key: 1f9ba190-c513-471b-a573-b8d008bb52fe

API keys can only access services and items that match their assigned privileges. To learn more about configuring privileges, go to API key credentials > Privileges. This example shows how to access the geocoding service directly by setting the token parameter to an API key.

July 29, 2025 - Limited Scope API Keys: These API ... Example: The Twitter API offers a limited scope API key that restricts access to specific areas of the Twitter API, such as read-only access to user timelines or direct messaging...

API keys that are embedded in code can be accidentally exposed to the public. For example, you may forget to remove the keys from code that you share.

Once the key is stolen, it has no expiration, so it may be used indefinitely, unless the project owner revokes or regenerates the key. While the restrictions you can set on an API key mitigate this, there are better approaches for authorization. For examples, see Authenticating users.

Another benefit of this approach is the ability to set API keys with different permissions in different environments such as development, staging, and production without changing the code you deploy to those environments. The examples below show how to store your key in a variable named SENDGRID_API_KEY.

In the API restrictions section, select Restrict key, then add to the list all of the APIs to which you want the API key to have access. Make sure to not include the API for which you're creating a separate API key (in this example, Super Service API).
