Integrations

n8n calls integrations nodes.

Nodes are the building blocks of workflows in n8n. They're an entry point for retrieving data, a function to process data, or an exit for sending data. The data process includes filtering, recomposing, and changing data. There can be one or several nodes for your API, service or app. You can connect multiple nodes, which allows you to create complex workflows.

Built-in nodes

n8n includes a collection of built-in integrations. Refer to Built-in nodes for documentation on all n8n's built-in nodes.

Community nodes

As well as using the built-in nodes, you can also install community-built nodes. Refer to Community nodes for more information.

Credential-only nodes and custom operations

One of the most complex parts of setting up API calls is managing authentication. n8n provides credentials support for operations and services beyond those supported by built-in nodes.

• Custom operations for existing nodes: n8n supplies hundreds of nodes to create workflows that link multiple products. However, some nodes don't include all the possible operations supported by a product's API. You can work around this by making a custom API call using the HTTP Request node.
• Credential-only nodes: n8n includes credential-only nodes. These are integrations where n8n supports setting up credentials for use in the HTTP Request node, but doesn't provide a standalone node. You can find a credential-only node in the nodes panel, as you would for any other integration.

Refer to Custom operations for more information.

Generic integrations

If you need to connect to a service where n8n doesn't have a node, or a credential-only node, you can still use the HTTP Request node. Refer to the node page for details on how to set up authentication and create your API call.
