# Set up Wolfram Alpha credentials in Duaer

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

The Duaer Wolfram Alpha API credential needs one key:

1. Sign in to the [Wolfram Alpha developer portal](https://developer.wolframalpha.com/), click Get an App ID to create an app, and copy the App ID.
2. Put it in App ID and save.

## Wolfram Alpha API fields in Duaer <a href="#wolfram-alpha-api" id="wolfram-alpha-api"></a>

In Duaer, choose Wolfram Alpha API when you create a credential, then fill in these fields:

- App ID (required, secret)

When you save, Duaer tests the connection with these values.

Duaer nodes that use it: [Wolfram Alpha](/integrations/builtin/cluster-nodes/sub-nodes/n8n-nodes-langchain.toolwolframalpha.md).

## Save the connection in Duaer

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

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

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