token:update

The Update Tokens endpoint uses a different content-type to support merge-patch operations. Requests need the Content-Type header to be set to application/merge-patch+json. Requests made with a different Content-Type header value will receive a 415 Unsupported Media Type response code. For more information on merge-patch, see RFC 7386.

`cvc`	false	string	`null`	Three or four-digit card verification code

Token Expiration

By default a created token will not expire, however, users can optionally set the expires_at property with an ISO8601 DateTime when creating a token to determine its expiration date. An expired token is deleted from the tenant up to 1 hour after it's expiration time.

Expiration Date Formats

Format	Example
`DateTime` String w/ Offset	8/26/2030 7:23:57 PM -07:00
`ShortDate` String	9/27/2030

If an offset is not provided with the DateTime string, it's considered that the provided time is in UTC. When using the ShortDate format, the expiration time will be set as 12AM UTC.
