ClientCredentialsOAuth2ClientFilter
Authenticates OAuth 2.0 clients by using the client’s OAuth 2.0 credentials to obtain an access token from an Authorization Server, and injecting the access token into the inbound request as a Bearer Authorization header. The access token is valid for the configured scopes.
The ClientCredentialsOAuth2ClientFilter obtains the client’s access token by
using the client_credentials grant type. Client authentication is provided by
the endpointHandler property, which uses a client authentication filter, such
as
ClientSecretBasicAuthenticationFilter.
The filter refreshes the access token as required.
Use the ClientCredentialsOAuth2ClientFilter in a service-to-service context, where services need to access resources protected by OAuth 2.0.

}Properties
"secretsProvider": SecretsProvider reference, required-
The SecretsProvider to query for passwords and cryptographic keys.
"tokenEndpoint": configuration expression<url>, required-
The URL to the Authorization Server’s OAuth 2.0 token endpoint.

Configure this property as a Chain, using one of the following client authentication filters:
{ "name": "myHandler", "type": "Chain", "config": { "handler": "ForgeRockClientHandler", "filters": [ { "type": "ClientSecretBasicAuthenticationFilter", "config": { "clientId": "myConfidentialClient", "clientSecretId": "my.client.secret.id", "secretsProvider" : "mySystemAndEnvSecretStore", } } ] } }Default: ForgeRockClientHandler
"clientId": configuration expression<string>, required-
This property is deprecated. Use endpointHandlerinstead. For more information, refer to the Deprecated section of the Release Notes.The ID of the OAuth 2.0 client registered with the Authorization Server.
If you use the deprecated properties, provide
clientId,clientSecretIdto obtain the client secret, which authenticates using theclient_secret_basicmethod. "clientSecretId": configuration expression<secret-id>, required-
This property is deprecated. Use endpointHandlerinstead. For more information, refer to the Deprecated section of the Release Notes.The ID to use when querying the
secretsProviderfor the client secret.This secret ID must point to a GenericSecret.
"handler": Handler reference or inline Handler declaration, optional-
This property is deprecated. Use endpointHandlerinstead. For more information, refer to the Deprecated section of the Release Notes.The Handler to use to access the Authorization Server’s OAuth 2.0 token endpoint. Provide either the name of a handler object defined in the heap or specify a handler object inline.
Default: ClientHandler
