You instruct an agent to book you a flight to London.
No more than €350.
On a specific day and within a specific time window.
No more than one stop.
A window seat.
The agent has four days.
At this point, there is no specific financial action yet.
You have given the agent a bounded mandate.
Within this mandate, the agent can search, compare offers, and later make a specific selection on its own. The flight it eventually books may not even exist at the time you give the instruction.
Only later does the agent turn that mandate into a concrete action:
Book this flight for €345.
And this is where the authorization question changes.
The resulting payment can then enter the existing authorization and processing infrastructure.
But before that, an autonomous agent introduces a different question that must be answerable:
Why is this agent allowed to make this specific booking?
Is the price within the mandate?
Do the date and time window match?
Does the itinerary have no more than one stop?
Does the booking meet the seat requirement?
Is the mandate still valid?
The payment itself does not contain these answers.
The agent has turned a delegated mandate into a concrete financial action. This introduces an authorization question before the payment transaction itself: whether the specific agent action is still covered by the delegated mandate.
Delegated mandate → Agent → Concrete action → Mandate check → Payment transaction → Payment authorization
That is the structural change:
In agentic payments, the payment transaction is no longer the starting point for authorization.
