Usage In n8n Workflows

Add Redis Node: Use the Redis node in your n8n workflows
Configure Connection: Enter the connection details shown below
Choose Operations: Use SET, GET, HSET, PUBLISH, SUBSCRIBE, and other Redis commands

Redis Node Configuration

When adding a Redis node in your n8n workflow, use these credentials:

Host: ${{redis.REDIS_HOST}}
Port: ${{redis.REDIS_PORT}} (typically 6379)
Username: ${{redis.REDIS_USERNAME}} (typically "default")
Password: ${{redis.REDIS_PASSWORD}}
Database: 0
Use TLS/SSL: No (unless specifically configured)

Common Workflow Use Cases
