# Set up Zabbix credentials in Duaer

Store Zabbix 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 Zabbix API token <a href="#get-an-api-token" id="get-an-api-token"></a>

The Duaer Zabbix API credential:

1. In Zabbix, open Users > API tokens, click Create API token, pick the user and expiry, and put the token in API Token.
2. Put the Zabbix frontend address, such as https://zabbix.example.com, in URL. Duaer adds /api_jsonrpc.php itself.

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

## Zabbix API fields in Duaer <a href="#zabbix-api" id="zabbix-api"></a>

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

- URL (required)
- API Token (required, secret)

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

## Save the connection in Duaer

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

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

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