Agentic commerce authorisation
Agentic commerce needs authorisation that merchants, PSPs, and risk teams can independently verify. Signed outcomes beat opaque partner assertions. AffixIO returns allow or deny for payment and eligibility at checkout and settlement.
Definition
Agentic commerce authorisation is the set of signed eligibility and payment permission checks that let merchants proceed with agent-led purchases under policy.
Field note. Post-capture authorisation on agent orders produces dispute packets without replayable proof of permission.
A complete authorisation chain
Combine agent eligibility, user consent, and payment permission. Each can be a signed AffixIO outcome. Merchants verify at checkout before capture.
Who issues the proof? A policy authority or issuer you control. AffixIO verifies at the merchant or platform boundary.
Settlement and partners
Proof metadata can travel into settlement and partner reporting. It does not replace your commercial contracts. It gives those contracts something concrete to reference.
Partner programmes can standardise on AffixIO verify so every merchant sees the same allow or deny shape.
Operational detail for agentic commerce authorisation
For agentic commerce authorisation, provision sandbox circuits that mirror production predicates before you expose live agent traffic. Capture sample allow and deny payloads for regression tests.
Keep identity and rich attributes with the issuer. Verifiers receive outcomes and Merkle metadata only. Sync audit refs to your SIEM or order store after the gate returns.
Policy drift
Partner trust is not merchant proof
Marketplaces and agent operators may assert that a purchase is authorised. Merchants still need something they can verify and store.
Opaque partner assertions
Cannot be re-checked in a chargeback without depending on the partner.
Split liability
Issuer, merchant, and agent operator disagree without a shared cryptographic artefact.
Incomplete gates
Identity without payment permission, or consent without agent eligibility, leaves holes.
MCP hook
Authorise agentic commerce before capture, not after dispute
Agentic checkout flows need verifier-checkable authorisation at the merchant boundary. Wire verify upstream of PSP capture so deny stops the transaction before side effects.
