Zendesk (SP-initiated) Integration Guide


Use this guide to enable Multi-Factor Authentication and Single Sign-on (SSO) access via SAML to Zendesk.


1. Have a Zendesk account

2. Create a New Realm for the Zendesk integration in the SecureAuth IdP Web Admin

3. Configure the following tabs in the Web Admin before configuring the Post Authentication tab:

  • Overview – the description of the realm and SMTP connections must be defined

  • Data – an enterprise directory must be integrated with SecureAuth IdP

  • Workflow – the way in which users will access this application must be defined

  • Multi-Factor Methods – the Multi-Factor Authentication methods that will be used to access this page (if any) must be defined

SecureAuth IdP Configuration Steps



1. In the Profile Fields section, map the directory field that contains the user's Zendesk ID to the SecureAuth IdP Property

For example, add the Zendesk ID field to the Email 2 Property if it is not already contained somewhere else


Click Save once the configurations have been completed and before leaving the Data page to avoid losing changes

Post Authentication


2. Select SAML 2.0 (SP Initiated) Assertion Page from the Authenticated User Redirect dropdown in the Post Authentication tab in the Web Admin

3. An unalterable URL will be auto-populated in the Redirect To field, which will append to the domain name and realm number in the address bar (Authorized/SAML20SPInit.aspx)

4. A customized post authentication page can be uploaded, but it is not required

User ID Mapping


5. Select the SecureAuth IdP Property that corresponds to the directory field that contains the Zendesk ID (Email 2)

6. Select urn:oasis:names:tc:SAML:1.1:nameid-format:unspecified from the Name ID Format dropdown (default)

Select a different option if Zendesk requires it, which the Service Provider (SP) will provide

7. Select False from the Encode to Base64 dropdown

SAML Assertion / WS Federation


8. Provide the SP Start URL to enable SSO and to redirect users appropriately to access Zendesk

For example, the SP Start URL would be


9. Leave the Signing Cert Serial Number as the default value, unless there is a third-party certificate being used for the SAML assertion

If using a third-party certificate, click Select Certificate and choose the appropriate certificate

10. Download the Assertion Signing Certificate, which will be used in the Zendesk Configuration Steps

The Certificate Fingerprint will need to be extracted from the certificate


Click Save once the configurations have been completed and before leaving the Post Authentication page to avoid losing changes

Forms Auth / SSO Token

Optionally, in the Forms Auth / SSO Token section, click the View and Configure FormsAuth keys/SSO token link to configure the token/cookie settings and configure this realm for SSO.

6. Provide the Certificate fingerprint from the Assertion Signing Certificate in the SecureAuth IdP Web Admin (step 10)

7. Set the Remote logout URL to any URL to where end-users will be redirected after logging out of Zendesk
