How do you authenticate your API request?

The Three Most Common API Authentication Methods

1. Basic authentication: You send your username/password alongside every API call 🏴‍☠️.
2. API Key: The service creates a unique key for your account and you pass it alongside every request 🤓.
3. OAuth: A user clicks on a sign-in button, grants permission, and your app can authenticate each request with an access_token 🚀.

How would you authorize a user via an API?

Steps

1. Authorize user: Request the user's authorization and redirect back to your app with an authorization code.
2. Request tokens: Exchange your authorization code for tokens.
3. Call API: Use the retrieved Access Token to call your API.
4. Refresh tokens: Use a Refresh Token to request new tokens when the existing ones expire.

How does API authentication work?

API Key Authentication

The API key is usually a long series of numbers and letters that you either include in the request header or request URL. When the client authenticates the API key, the server stamps their identity and allows them to access data.

What is API authorization?

Involves checking resources that the user is authorized to access or modify via defined roles or claims. For example, the authenticated user is authorized for read access to a database but not allowed to modify it. The same can be applied to your API.

How do I recover my username and password in REST API?

Note that the user name is case-sensitive. Encode this user name and password string in base64 encoding. Include this encoded user name and password in an HTTP Authorization: Basic header. When you use HTTP POST, PATCH, or DELETE methods, you must provide extra authentication, as well as a user name and password.

Which authentication is best for web API?

OAuth 2.0 is the best choice for identifying personal user accounts and granting proper permissions. In this method, the user logs into a system. That system will then request authentication, usually in the form of a token.

Is API key authentication or authorization?

API keys aren't as secure as authentication tokens (see Security of API keys), but they identify the application or project that's calling an API. They are generated on the project making the call, and you can restrict their use to an environment such as an IP address range, or an Android or iOS app.

Is a Web service the same as an API?

There you have it: an API is an interface that allows you to build on the data and functionality of another application, while a web service is a network-based resource that fulfills a specific task. Yes, there's overlap between the two: all web services are APIs, but not all APIs are web services.

How many types of authentication are there in REST API?

Today, we're going to talk about Authentication. Though an often discussed topic, it bears repeating to clarify exactly what it is, what it isn't, and how it functions. We'll highlight three major methods of adding security to an API — HTTP Basic Auth, API Keys, and OAuth.

What is OAuth authentication REST API?

OAuth is an authorization framework that enables an application or service to obtain limited access to a protected HTTP resource. To use REST APIs with OAuth in Oracle Integration, you need to register your Oracle Integration instance as a trusted application in Oracle Identity Cloud Service.

What are the three types of authentication?

There are generally three recognized types of authentication factors:

• Type 1 – Something You Know – includes passwords, PINs, combinations, code words, or secret handshakes. ...
• Type 2 – Something You Have – includes all items that are physical objects, such as keys, smart phones, smart cards, USB drives, and token devices.

How can I secure my API without authentication?

To protect the keys, use a proxy. Make a server side component that holds the keys and access the backend, and your HTML page (or app, or Java, or whatever client application) will access it. And you cannot really know if the client connecting is your client.
