# Set up Qualys credentials in Duaer

Store Qualys 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.
## Use a Qualys API account <a href="#use-a-qualys-api-account" id="use-a-qualys-api-account"></a>

The Duaer Qualys API credential:

- Username and Password are a Qualys account with API access, ideally a dedicated API account.
- Requested With is the X-Requested-With header Qualys requires; it is preset and rarely needs changing.
- Use the API address of your Qualys platform in requests, such as https://qualysapi.qualys.com or https://qualysapi.qg2.apps.qualys.eu.

Duaer has no dedicated node for this service. In the HTTP Request node, set Authentication to Predefined Credential Type and pick the Qualys API credential. Refer to [custom operations](/integrations/custom-operations.md).

## Qualys API fields in Duaer <a href="#qualys-api" id="qualys-api"></a>

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

- Username (required)
- Password (required, secret)
- Requested With: User description, like a user agent. Default: a preset value.

## Save the connection in Duaer

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

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

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