Set up Hugging Face credentials in Duaer
Store Hugging Face connection details in Duaer for digital-organization nodes to use at runtime. Secrets are protected by the instance encryption key and are not written into node parameters.
Get a Hugging Face API key
The Duaer Hugging Face API credential needs one API key:
- Sign in to Hugging Face Access Tokens.
- Click Create new token. With Fine-grained, tick the permission to make calls to Inference Providers; Read also works. Copy the key right away; it is usually shown only once.
- In Duaer, create a Hugging Face API credential, paste the key into API Key, and save. Duaer tests the connection with it.
The Duaer connection test only checks the token itself. If the token passes but model calls return 403, the token usually lacks the Inference permission, or the model requires you to accept its terms on the model page first.
Hugging Face API fields in Duaer
In Duaer, choose Hugging Face API when you create a credential, then fill in these fields:
- API Key (required, secret)
When you save, Duaer tests the connection with these values.
Duaer nodes that use it: Embeddings Hugging Face Inference, Hugging Face Inference Model.
Save the connection in Duaer
Open Credentials and create Hugging Face. Fill in the key, OAuth, or server fields. After you save, digital-organization nodes reference this credential instead of putting the secret in a parameter.
Credential values are protected by the instance encryption key. If you change or lose that key, stored credentials cannot be decrypted. See the hosting notes on encryption keys.
Who can use this credential
Who can see or edit it follows projects and roles. Do not paste secrets into chat or variables. External vaults are covered under external secrets.
Questions
Do Hugging Face secret values appear in Duaer node parameters?
No. In Duaer, Hugging Face secrets stay in the credential. Nodes only reference the credential. Execution records should not show the plaintext secret either.
What usually stops a Hugging Face credential from saving in Duaer?
Wrong fields, an OAuth callback that does not match the instance URL, or a role that cannot create credentials. Check the fields Hugging Face expects, then confirm you can create credentials in that project.

IntegrationsRisks of community nodes in Duaer
Before you install a community node in Duaer, know the code comes from a source the instance admin trusts, and know what permissions it gets.
IntegrationsTroubleshoot community nodes in Duaer
When a Duaer community node will not install or run, check the version, permissions, and node docs, then the instance logs.
IntegrationsMake custom API calls for an app in Duaer
When a Duaer app node does not expose the API you need, use HTTP Request and reuse that app’s saved authentication.
