Flow

From agent intent to authorized payment.

Eight stages connect an autonomous decision to a governed, auditable transaction.
  1. 01

    Agent initiates action

    An AI agent determines that a purchase or payment is required.

  2. 02

    Identity verified

    PayHero identifies the agent and the organization it represents.

  3. 03

    Mandate retrieved

    The agent's delegated financial authority is loaded.

  4. 04

    Policy evaluated

    The proposed transaction is evaluated against relevant rules.

  5. 05

    Approval determined

    PayHero determines whether the transaction can proceed autonomously or requires human approval.

  6. 06

    Payment authorized

    The appropriate payment credential or payment rail is enabled.

  7. 07

    Transaction executes

    The merchant receives payment.

  8. 08

    Audit record created

    The complete decision and transaction history is recorded.
