# Set up Datadog credentials in Duaer

Store Datadog 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 Datadog API and application keys <a href="#get-api-and-application-keys" id="get-api-and-application-keys"></a>

The Duaer Datadog API credential:

1. In Datadog, open Organization Settings > API Keys and copy or create an API key for API Key.
2. Endpoints that read data also need an application key: create one under Application Keys and put it in APP Key.
3. Put your site’s API address in URL: keep the default https://api.datadoghq.com for US1, or use https://api.datadoghq.eu for the EU site.

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

## Datadog API fields in Duaer <a href="#datadog-api" id="datadog-api"></a>

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

- URL (required): Default: https://api.datadoghq.com.
- API Key (required, secret)
- APP Key (secret): For some endpoints, you also need an Application key.

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

## Save the connection in Duaer

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

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

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