How to pass access token url in authentication flow oauth2 (2024)

FAQs

How do I pass an API authentication token? ›

The second way to pass your API token is via a query parameter called key in the URL like below. Use of the X-Dataverse-key HTTP header form is preferred to passing key in the URL because query parameters like key appear in URLs and might accidentally get shared, exposing your API token. (Again it's like a password.)

Once an application has received an access token, it will include that token as a credential when making API requests. To do so, it should transmit the access token to the API as a Bearer credential in an HTTP Authorization header.

A redirect URL is used in OAuth 2.0 to redirect users to an application after they grant permission to access their account. Specifically, this URL is used in the authorization code flow with PKCE, which is an enhanced security method to prevent authorization code interception attacks.

The other way to make an API call with an access token is to add it to the request header. If using curl (a command line program that can be used for running API requests) you would specify the access token like this. Notice that the access_token is not in the URL at all. See the example on the API documentation site.

To send a request with the Bearer Token authorization header, you need to make an HTTP request and provide your Bearer Token in the "Authorization: Bearer {token}" HTTP header. A Bearer Token is a cryptic string typically generated by the server in response to a login request.

An OAuth Access Token is a string that the OAuth client uses to make requests to the resource server. Access tokens do not have to be in any particular format, and in practice, various OAuth servers have chosen many different formats for their access tokens.

What is an example of OAuth 2.0 authentication? ›

OAuth 2.0 allows users to share specific data with an application while keeping their usernames, passwords, and other information private. For example, an application can use OAuth 2.0 to obtain permission from users to store files in their Google Drives. This OAuth 2.0 flow is called the implicit grant flow.

The token can be verified via introspect endpoint or by signature. The most common way to build built-in token verification into the system is to introspect the token on the API Gateway and verify the signature on other services.

Auth URL - The endpoint for the API provider authorization server, to retrieve the auth code. Access Token URL - The provider's authentication server, to exchange an authorization code for an access token. Client ID - The ID for your client application registered with the API provider.

The OAuth process greatly depends on redirect URLs. Once an application receives successful authorization from a user, the authorization server guides the user back to the respective application.

We can do HTTP basic authentication URL with @ in password. We have to pass the credentials appended with the URL. The username and password must be added with the format − https://username:password@URL.

An API token follows a set series of steps. First, the API verifies the username and password from the payload. Once these are verified, the API sends an asset to your browser to be stored. Then anytime you send a query to the API, the access token is sent along with it.

Authentication is typically done by requiring the client to provide some form of credentials – such as a user name and password, an OAuth token, or a JSON Web Token (JWT). As an API owner, you can implement authentication in Apigee using policies.
