Hi,

I am trying to create a new payment instrument token (new card) when creating an authorization. The token creation for first time is well documented: https://developer.cybersource.com/docs/cybs/en-us/tms/developer/all/rest/tms/tms-mult-tkn-create-intro.html. Instead of using the tokenize endpoint we are using https://apitest.cybersource.com/pts/v2/payments with "CREATE_TOKEN". It return a customer token and payment token. But say I want to add a new card and link the card(new payment token) with existing customer token when call a the authorization api.https://apitest.cybersource.com/pts/v2/payments. Is this possible. I don't see it linking the new payment token with exiting customer token.
