# Nodes Contextual's Flow editor includes both Contextual-specific nodes as well as groups of nodes from the Node-RED community. In the Flow editor you will see nodes grouped into categories on the left-hand navigation. These can be easily searched. Contextual-specific nodes worth noting include: Object - These are custom nodes for interacting with Contextual's Object Types. Request - These are nodes that leverage Contextual [Connections](/documentation-and-resources/components-and-data/connections.md) to connect with external APIs or messaging infrastructures like Kafka or Pulsar. Event - Event nodes are for handling inbound and termination pages for event-based flows. --- # Agent Instructions: Querying This Documentation If you need additional information that is not directly available in this page, you can query the documentation dynamically by asking a question.
