Duo enroll user Rest Api Call java

gauravagarwal3371 — Thu, 03 Aug 2023 12:16:20 GMT

I want to enroll the user for duo authentication while I create a new user in my application. Is there any java client available which can be used for enrolling the user to DUO

You can use the Admin API examples in https://github.com/duosecurity/duo_client_java to figure out how to call the Auth API enroll endpoint https://duo.com/docs/authapi#/enroll or make use of the enroll response received by the preauth endpoint https://duo.com/docs/authapi#/preauth.

If your application is able to render a web page for authentication consider using our WebSDK instead, which will handle user enrollment for you.

I have use below like which is working fine:

1. Add below dependency to pom.xml'

<dependency>
    <groupId>com.duosecurity</groupId>
    <artifactId>duo-client</artifactId>
    <version>0.6.0</version>
</dependency>

2. User below code:

Note: All Other API are similar. Just change your intregation key, Secrete key, host, end point and parameters.
