Terminate an embedded payment widget session so the user can no longer complete it.
Terminate an embedded payment widget session so the user can no longer complete it.Authenticated with the operator’s application (Basic auth) credentials — the same application
whose secret signed the operator token that opened the session.The session cannot be reopened: the user is refused on their next
navigation or refresh inside the widget, and cannot revive the session by reloading. Terminating
a session the user has not opened yet is supported and is the safest way to cancel a payment you
have already handed off.Termination is idempotent — terminating an already-terminated session succeeds — but it is
refused in two cases, each of which means the money question is already settled:
the session’s payout is currently executing (409). Wait for the outcome; do not retry blindly.
the session has already completed (409). There is nothing left to terminate.
Note that termination takes effect on the user’s next navigation inside the widget; it does not
close an already-rendered screen.
