# Integrations in Duaer

Built-in triggers, actions, and credentials in Duaer. Community nodes are extra packages. Custom operations reuse saved authentication with HTTP Request.
## Where to go next

- [Built-in integrations](/integrations/builtin.md): triggers and actions that ship with the instance.
- [Built-in credentials hub](/integrations/builtin/credentials.md): per-service credential fields.
- [Custom operations](/integrations/custom-operations.md): HTTP Request when the app node lacks an operation.
- [Community node risks](/integrations/community-nodes/risks.md): read before installing a community package.

## Questions

### How do built-in integrations differ from community nodes in Duaer?

Built-in integrations ship with the instance. Community nodes are extra packages — read the risk notes before you install them.

### What if Duaer has no node for the API I need?

Check built-in nodes first. If the operation is missing, use custom operations: HTTP Request can reuse that app’s saved authentication.
