# Built-in credentials in Duaer

Per-service credential notes for Duaer built-ins. The create flow is in the credentials overview; node docs link to the matching service page.
## How to use this hub

One page per service, under /integrations/builtin/credentials/<service>/. In-product documentation links usually open that service page directly.

Learn create-and-save under [Create and edit credentials](/credentials.md), then return here for fields, OAuth scopes, or where to put the key.

## If you cannot find a service

- Match the slug to the path in the node docs (often lowercase).
- If there is only a node page, read its authentication notes, or use [custom operations](/integrations/custom-operations.md).
