Getting started

Mandate lets an AI agent spend money only within rules a person signed, and lets anyone check afterwards that it did. This API is for the other side of the payment: a seller, marketplace or auditor checking an agent's payment before shipping.

You need only the PayPal order id the payment arrived with. No account and no key: everything is checked with Mandate's public keys.

The answer says whether:

• the buyer signed a mandate that allows this purchase (an AP2 Intent Mandate),
• the cart is the exact cart the merchant signed and the buyer's rules allowed,
• PayPal's own record shows that amount captured,
• and, if the buyer approved it, that their device signed that cart (a passkey).

With the SDKCopy Anchor Link

import { MandateApiClient, ServerEnvironment } from "mandate-api";

const client = new MandateApiClient({ serverEnvironment: ServerEnvironment.Production });
const verdict = await client.verification.verifyOrder({ paypalOrderId: "5O190127TN364715T" });
if (!verdict.ok) throw new Error("Don't ship: this payment isn't backed by the buyer's mandate");

SDKs are generated by APIMatic for TypeScript, Python and C#.
