Supported Plugins

Besides the Admin APIs, Plugin configuration is also supported.

Authentication Plugins

• Basic Auth
• Key Auth
• HMAC Auth
• JWT Auth
• OAuth2
• LDAP

Security Plugins

• ACL
• IP Restriction

Traffic Control Plugins

• Rate Limiting
• Request Size Limiting
• Request Termination

Only those plugins are supported which might need configuration through code. For example, adding rate limit for a new consumer when there is a new signup. Plugins which require one time configuration are not supported.

Example Usage

To add credentials for a new Consumer for Basic Auth

kongClient.getBasicAuthService().addCredentials("con-su-mer-id", "username", "password");

To add OAuth2 Plugin for an API

//See: RetrofitApiPluginServiceTest.java
kongClient.getApiPluginService().addPluginForApi(API_NAME, oauth2Plugin);

To add an Application for a Consumer for OAuth2

//See: RetrofitOAuth2ManageServiceTest.java
kongClient.getOAuth2ManageService().createConsumerApplication(CONSUMER_ID, 
    new Application(appName, appRedirectUrl, appClientId, appClientSecret));

To do the OAuth2 Process (Authorization Code)

//See: RetrofitOAuth2ProcessServiceTest.java
kongClient.getOAuth2ProcessService().authorize(API_URI, authorizationRequest);
kongClient.getOAuth2ProcessService().grantToken(API_URI, grantTokenRequest)
