When building applications that interact with third-party services or APIs, using API keys for authentication and authorization is common. However, exposing these keys in your codebase can pose significant security risks. Malicious actors could misuse your API keys, leading to unauthorized access, data breaches, or financial losses.
Environment Variables
One effective way to hide API keys is by using environment variables. Environment variables are set outside of the application code and are accessible during runtime. They are commonly used to store sensitive data like API keys and database credentials without hardcoding them into the source code.
Steps to Hide API Keys using Environment Variables
Step 1: Create a .env File: Start by creating a file named `.env` in the root directory of your Node.js project. This file will store your API keys and other sensitive information.
Step 2: Install dotenv Package: Install the `dotenv` package, which allows us to read variables from the `.env` file into Node.js environment.
npm install dotenv
Step 3: Configure .env File: Add your API keys to the `.env` file in the format `KEY_NAME=your-api-key`. For example:
API_KEY=your-api-key-here
Step 4: Load Environment Variables in Node.js: In your Node.js application entry file (e.g., `app.js`), import and configure `dotenv` to load environment variables from the `.env` file.
require('dotenv').config();
Step 5: Access Environment Variables: Now, you can access your API keys as environment variables in your Node.js application using `process.env`.
const apiKey = process.env.API_KEY;
This way, your API keys remain hidden from the source code and are accessed securely through environment variables.
Conclusion
Securing API keys is crucial for the overall security of your Node.js applications. By utilizing environment variables and the dotenv package, you can effectively hide sensitive information like API keys from prying eyes. Always ensure you never expose your API keys in public repositories or client-side code to minimize security risks.

You can use a route handler to create a proxy endpoint that will take the request from the client, and then make the request to the 3rd party API on the server. This way, the client never sees the API key, and you can do whatever you want with the response before sending it back to the client.
Open the Google Cloud Console Google Maps Platform Credentials page. Select the API key that you want to restrict. On the Edit API key page, under API restrictions: Select Restrict key.

The standard way to achieve your goal is in the action builder where you select the authentication method. The API key will be encrypted and stored on OpenAIs servers. Then when the action is executed the API key will be send with the request headers and cannot be viewed by the users.
In either the project that your API is configured in, or a project that your API is enabled in, create an API key for each customer that has the API key restrictions that you need.
Securing API keys is important to ensure that unauthorized access isn't possible. Secure key management systems or secrets management services should be used to store the keys. Additionally, encrypting the keys at rest will further enhance protection and security.
You cannot hide or protect anything that is client-side when the game is running in a browser. If you don't want the true API key to be visible and directly usable, you have to take it out of the client, move it behind an authenticated web API back-end, and let that back-end proxy the request for authenticated users.
Click Save. The system will display the key and the secret. Copy it for future reference. if your Key and Secret is set up, see Using API Hooks for more information on how to use the API Hook.
If the key is needed by JavaScript, then no matter what you do, it will eventually end up in clear text on the client. If an API key is supposed to be secret, then you'd proxy your requests through a server-side language like PHP rather than making them directly from the client using JavaScript.
These keys are typically kept confidential and should be securely managed to prevent unauthorized access to sensitive data or actions within the API. Secret API keys serve as secure tokens to authenticate and authorize requests made to your API.
