# Set up Groq credentials in Duaer

Store Groq 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 Groq API key <a href="#get-an-api-key" id="get-an-api-key"></a>

The Duaer Groq credential needs one API key:

1. Sign in to [the GroqCloud console](https://console.groq.com/keys).
2. Open API Keys and click Create API Key. Copy the key right away; it is usually shown only once.
3. In Duaer, create a Groq credential, paste the key into API Key, and save. Duaer tests the connection with it.

## Groq fields in Duaer <a href="#groq" id="groq"></a>

In Duaer, choose Groq 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: [Groq Chat Model](/integrations/builtin/cluster-nodes/sub-nodes/n8n-nodes-langchain.lmchatgroq.md).

## Save the connection in Duaer

Open Credentials and create Groq. 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 Groq secret values appear in Duaer node parameters?

No. In Duaer, Groq secrets stay in the credential. Nodes only reference the credential. Execution records should not show the plaintext secret either.

### What usually stops a Groq 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 Groq expects, then confirm you can create credentials in that project.
