To access your organization's Help Center or to submit tickets, a user of your app must have an identity so they can authenticate as a Zendesk Support user. You can set two types of identities for a user:
To determine which option is best for your organization, see Authentication decision in the SDK integration checklist.
On the Zendesk Support side, an administrator must enable the chosen option in the admin interface. If you're a Zendesk Support admin, see Registering the application in Zendesk Support in the Support Help Center.
Note: The Zendesk SDK for Unity is intended for end users only. Authenticating with an agent email address will cause a 403 authentication error. Please be aware of this when testing your integration.
See JWT authentication.
