The Trifacta® REST APIs support the following methods of authentication.
Authenticating user must be a valid user of the deployed instance of the Trifacta platform.
API Access Token Authentication
API access tokens can be acquired and applied to your requests to obscure sensitive Personally Identifiable Information (PII) and are compliant with common privacy and security standards. These tokens last for a preconfigured time period and can be renewed as needed.
Tip: API access tokens are the preferred method of authentication.
NOTE: This feature may need to be enabled in your instance of the Trifacta platform. For more information, see Enable API Access Tokens.
- You submit a request to create a new access token.
- You can create and delete access tokens through the Settings area of the Trifacta application. See Access Tokens Page.
- You can create access tokens through the REST API endpoint.
- If you do not have a valid access token, you must submit your request to the endpoint using one of the other forms of authentication.
- If you do have a valid access token, you can use it with your submission to generate a new access token.
- See API AccessTokens Create v4.
- With each request, you submit the token as part of the
- Continue using the token. As needed, you can create and use additional tokens. There is no limit to the number of tokens you can create.
Tip: API access tokens work seamlessly with platform-native SAML and LDAP SSO authentication. They do not work with the reverse proxy method of SSO authentication. Details are below.
For more information on this process, see Manage API Access Tokens.
As request parameters, you can submit username/password under Basic Auth to any REST API endpoint.
NOTE: You must submit authentication credentials with each request to the platform.
NOTE: The user must have permissions to execute the endpoint action.
This example submits authentication requirements over HTTP, including the username and password (
|Required username and password.|
|Required paths and filenames for storage of send and receive HTTP cookies.|

You can use the APIs in SSO environments. Below, you can review the best method of authenticating to the APIs based on your SSO environment:
|SSO Type||API Auth|
|Platform-native SAML||API access tokens work seamlessly. Basic auth does not work.|
|Platform-native LDAP-AD||API access tokens work seamlessly. Basic auth does not work.|
|Reverse proxy SAML||Use basic auth described below. Additional configuration may be required.|
|Reverse proxy LDAP-AD||Use basic auth described below. Additional configuration may be required.|
In a single sign-on environment, you can use basic authentication to interact with the APIs.
NOTE: Enabling SSO integration with the Trifacta platform requires additional configuration. See Configure SSO for AD-LDAP.
However, some changes are required:
- Basic authentication to the gateway must be enabled as part of the configuration for the reverse proxy. This feature is enabled by default, but please verify that it has not been explicitly disabled in your environment. For more information, see Configure SSO for AD-LDAP.
- You must authenticate using the SSO principal as the username and the LDAP or AD password associated with that user.
- You must authenticate to the SSO gateway. In the Trifacta platform, this value corresponds to the
NOTE: For the protocol identifier, you can also use
https if SSL is enabled. See Install SSL Certificate.
|LDAP principal and password associated with that username.|
For more information, see Configure SSO for AD-LDAP.
In a Kerberos environment, credentials must be submitted with each request using the SPNEGO Auth method.
- Kerberos is a network authentication protocol for client/server applications.
- SPNEGO provides a mechanism for extending Kerberos to Web applications through HTTP.
- For more information on the differences, see https://msdn.microsoft.com/en-us/library/ms995330.aspx#http-sso-2_topic2.
Credentials are authenticated by the KDC for each request.
NOTE: SPNEGO must be enabled and configured for your REST client or programming library.
Example 1 - Embedded in Java:
SPNEGO requires a custom client. The following SPNEGO client enables submission of URL-based authentication parameters from within Java: http://docs.oracle.com/javase/6/docs/technotes/guides/security/jgss/lab/part5.html
Example 2 - Using cURL:
To use cURL:
Verify that your version of cURL supports GSS:
