OAuth is a delegated authorization framework for REST/APIs. It enables apps to obtain limited access (scopes) to a user’s data without giving away a user’s password. It decouples authentication from authorization and supports multiple use cases addressing different device capabilities.
What is OAuth authentication in REST API?
Overview. OAuth is an authentication protocol that enables a user (resource owner) to grant a third-party application (consumer/client) access to their information on another site (resource).
How do I add OAuth to my API?
Creating an OAuth 2.0 provider API
- In a command window, change to the project folder that you created in the tutorial Tutorial: Creating an invoke REST API definition.
- In the API Designer, click the APIs tab.
- Click Add > OAuth 2.0 Provider API.
- Complete the fields according to the following table: …
- Click Create API.
The OAuth 2.0 framework provides this delegation in the form of an access token, which the application can use to act on behalf of the user. The access token is presented to the API (the “resource server”), which knows how to validate whether the access token is active.
How does OAuth protect REST API?
Secure Spring REST API Using OAuth2
- Configure Spring Security and the database.
- Configure the authorization server and resource server.
- Get an access token and a refresh token.
- Get a protected Resource (REST API) using an access token.
How does OAuth authentication work?
OAuth doesn’t share password data but instead uses authorization tokens to prove an identity between consumers and service providers. OAuth is an authentication protocol that allows you to approve one application interacting with another on your behalf without giving away your password.
How does API authentication work?
Authentication schemes provide a secure way of identifying the calling user. Endpoints also checks the authentication token to verify that it has permission to call an API. Based on that authentication, the API server decides on authorizing a request.
What is OAuth in Web API?
OAuth is a token based authorization mechanism for REST Web API. You develop the authorization with the API only once up until the expiration time of the token. The generated token is then used each time the REST Web API is called, saving an authorization step every time the REST Web API is called.

How do I set up OAuth?
Setting up OAuth 2.0

How do you authenticate APIs?
You can authenticate API requests using basic authentication with your email address and password, with your email address and an API token, or with an OAuth access token. All methods of authentication set the authorization header differently. Credentials sent in the payload (body) or URL are not processed.
What is one benefit that OAuth provides over an API key approach?
However, OAuth provides several improvements over API keys. For starters, access tokens can be tied to particular scopes, which restrict the types of operations and data the application can access. Also, combined with refresh tokens, access tokens will expire, so the negative effects could have a limited impact.
Principles of OAuth2.
OAuth 2.0 is an authorization protocol and NOT an authentication protocol. As such, it is designed primarily as a means of granting access to a set of resources, for example, remote APIs or user’s data.
Is OAuth more secure than API key?
API Key can be an easy way to enforce some authentication. OAuth is more sophisticated with more options but also needs more knowledge to get implemented correctly, not only on the client but also on the server-side.
How do I secure API request?
Best Practices for Securing APIs

How do I secure my Web API?
Securing your API against the attacks outlined above should be based on: Authentication – Determining the identity of an end user. In a REST API, basic authentication can be implemented using the TLS protocol, but OAuth 2 and OpenID Connect are more secure alternatives.
