SASL/OAUTHBEARER authenticationv3.15+
Authenticate to Confluent Cloud using SASL/OAUTHBEARER. Kong Gateway fetches and renews OAuth 2.0 access tokens automatically using the client credentials grant.
Prerequisites
-
An OAuth 2.0 identity provider that supports the client credentials grant
Environment variables
-
BOOTSTRAP_SERVER_HOST: The bootstrap server host. -
KAFKA_TOPIC: The name of the Kafka topic. -
TOKEN_ENDPOINT_URL: The URL of the OAuth 2.0 token endpoint. -
CLIENT_ID: The OAuth 2.0 client ID. -
CLIENT_SECRET: The OAuth 2.0 client secret.
