CreateSsoToken

Create a single use, client or sub-account single sign-on access token

Tokens are valid for a maximum of 60 seconds.

WARNING: The token returned provides complete authentication to the associated client account. It is imperative that scripts ensure the actor who triggers this API call and receives this data has verified their identity and ownership for the associated account. IE, the invocation of this API should be behind your own user authentication and account mapping engine.

NOTE: The associated endpoint where this token is redeemed is only for one-time trusted tokens and will not attempt to enforce captcha or 2FA authorization controls common to the WHMCS login form.

A valid destination is expressed using the short term like “clientarea:services”. Possible destinations are documented at https://docs.whmcs.com/WHMCS_Single_Sign-On_Developer_Guide#Supported_Destinations
