Revokes one of the agent's x402 mandates: from the moment this returns, it authorizes no new payment. A signing request already past its budget check when the cancel landed can still receive its signature, as can a retry of it under the same `X-Idempotency-Key`; both are the same single payment, committed before the cancel. Any authorization signed under the mandate stays payable by the seller until its `valid_before`, which is never more than 10 minutes after it was signed, and its hold keeps counting against the budget until it settles or is released. Cancel is idempotent: cancelling a cancelled mandate answers 200 with the mandate unchanged, `revoked_at` still the time of the first cancel. To change a budget rather than stop it, create a new mandate instead: it replaces this one. ## OpenAPI ````yaml /openapi.yaml post /payment-agents/{payment_agent_id}/x402/mandates/{mandate_id}/cancel openapi: 3.0.3 info: title: Dakota Platform API version: 1.0.0 description: >- Combined API specification for Dakota Platform services: - Issuance API: Asset minting and burning operations - Onboarding API: Know Your Business/Customer verification - On/Off Ramp API: Managing on-ramp and off-ramp accounts - Recipients API: Managing destinations for KYB'd entities - Transactions API: Viewing transaction history across platform operations ## Authentication and API Headers All API endpoints require the following headers: - `X-Idempotency-Key`: Required for all POST endpoints to ensure request idempotency - `x-api-key`: Required for authentication across all endpoints Note: On /applications endpoints you need a token for authentication instead of a x-api-key - `x-application-token`: Required for authentication on public /applications endpoints (alternative to `x-api-key` where documented) ## Rate Limits Requests are rate limited per API key. Every response includes the following headers: | Header | Description | | --- | --- | | `X-RateLimit-Limit` | Maximum requests allowed in the current one-minute window. | | `X-RateLimit-Remaining` | Requests remaining in the current window. | | `X-RateLimit-Reset` | Absolute Unix timestamp (seconds since epoch) when the current rate-limit window resets. | When a request is throttled (`429`), responses also include `Retry-After` with seconds to wait before retrying. servers: - url: https://api.platform.dakota.xyz description: Production environment - url: https://api.platform.sandbox.dakota.xyz description: Sandbox — safe for testing with simulated data security: - ApiKeyAuth: [] tags: - name: Agentic Payments x-beta: true description: >- Beta — agent-driven payments: provision agents, draft and approve spending mandates, accept reviewed instructions, and manage scheduled payments. **Prerequisites:** Customer onboarded; signer groups attached for recognition. **Related:** Wallets, Signer Groups, Transactions - name: Mandates x-beta: true description: >- Beta — spending mandates: signed, signer-bound authorizations governing what may be spent, approved or cancelled by a second recognized signer (§8 — the dual-control rule that every mandate mutation must be signed by a recognized signer OTHER than the bound one).

Every change is also delivered as a webhook event. **Prerequisites:** Customer must be onboarded and the cards capability must be available. **Related:** Customers, Wallets, Events ### Webhook event catalog (v1) Every card-family event a client can subscribe to, in one place: | Event | Fires when | | -- | -- | | `cardholder.created` | A cardholder is created. | | `cardholder.updated` | Any cardholder change, including every review-status transition and deletion (`status: closed`). | | `cardholder.information_requested` | A reviewer asks for more information; the payload lists the open requirements. Not yet emitted; the review pipeline that opens a request for information is still to land. | | `card.created` | A card is created. | | `card.updated` | Any card change: status, spend limit, last4, freeze sources. A close arrives here with `status: closed`. | | `card_transaction.created` | The first event for a transaction, normally an authorization (`status: authorized`) placing a hold. A declined authorization also arrives here, with `status: declined`. | | `card_transaction.updated` | Every later change to the same transaction (see below). | | `wallet.card_enablement.completed` | A wallet's card-settlement enablement became active. | **Card event ordering.** `card.created` and `card.updated` carry the card as it stands after the change, including `version` and `freeze_sources` (always an array, empty when nothing holds the card). `version` is strictly increasing per card and matches the `version` on the card resource. Deliveries can arrive out of order, so keep the highest `version` you have applied for each card and drop any event whose `version` is not greater than it. **One transaction stream.** Holds, releases, partial clearings, settlement, returns, disputes and force posts are not separate event types. They are `status` transitions on the transaction, delivered as `card_transaction.updated` with the same payload shape as `card_transaction.created`: | What happened | `status` on the event | | -- | -- | | Transaction known before its first authorization event | `pending` (on `card_transaction.created`) | | Hold placed (authorization) | `authorized` (on `card_transaction.created`, or `card_transaction.updated` after a `pending` start) | | Hold released without clearing (merchant, issuer or network reversal) | `auth_reversed` | | Hold expired unused | `expired` | | Part of the hold settled | `partially_cleared` (with the new `cleared_amount`) | | Fully settled | `cleared` | | Settled with no prior hold | `force_posted` | | Merchant refund | `returned`, on a new card transaction for the refund; the original purchase stays `cleared`. The network returned the money; read `refund_state` for whether it reached the customer's wallet (`pending` then `paid`). `returned` alone is not proof of payout. | | Chargeback opened | `disputed` (reserved; not emitted yet) | | Authorization refused | `declined` (on `card_transaction.created`, or `card_transaction.updated` when the transaction already exists). Moves no money; read `decline_reason` and `decline_code` for why. | `outstanding_amount` is the part of `cleared_amount` that no authorization covered, less any refunds: non-zero after a force post or an over-capture. **Naming.** A dotted segment names a sub-resource of the resource before it, so `wallet.card_enablement.*` is a wallet's card enablement. `card_transaction.*` carries an underscore because the resource is `card_transactions`, a top-level resource, not a sub-resource of a card. It is not a typo, and there is no `card.transaction.*` family, and no separate settlement event: settlement is a `status` on `card_transaction.updated`. - name: Accounts description: >- Manage account resources used for onramp, offramp, and swap operations. **Prerequisites:** Customer must be created and network/asset constraints must be known. **Related:** Customers, Transactions, Auto Transactions, Info - name: Auto Transactions description: >- Manage automated transaction configurations and execution history for account automation workflows. **Prerequisites:** Source account must exist and be configured for automation. **Related:** Accounts, Transactions, Events - name: Onboarding description: >- Manage KYB/KYC onboarding lifecycle, application documents, attestations, and verification steps. **Prerequisites:** Customer context and required entity/application metadata. **Related:** Customers, Exceptions, Recipients, Transactions - name: Policies description: >- Define and manage policy objects and rules used for transaction governance and risk controls. **Prerequisites:** Wallet and signer group resources should be configured for enforcement scenarios. **Related:** Wallets, Signer Groups, Transactions - name: Signer Groups description: >- Manage signer groups and signer assignments for multi-party authorization models. **Prerequisites:** Wallets should exist before linking signer groups. **Related:** Wallets, Policies, Transactions - name: Authentication description: >- Manage API authentication credentials and key lifecycle for platform access. **Prerequisites:** Client organization must be provisioned. **Related:** Users, Info - name: Users description: >- Manage client users, roles, and identity metadata for platform access control. **Prerequisites:** Auth credentials and client context must be established. **Related:** Authentication - name: Webhooks description: >- Manage outbound webhook targets and delivery configuration for event notifications. **Prerequisites:** Subscriber endpoint must be reachable and secured. **Related:** Events, Authentication - name: Payouts description: >- Manage where Dakota sends your accrued developer-fee payouts. **Prerequisites:** Auth credentials and client context must be established. **Related:** Events - name: RD Marketing Fee description: >- Everything behind your RD marketing fee: read what a month came to, declare the wallets you hold outside Dakota so the RD in them counts, and say where the fee should be sent. **Prerequisites:** Client must be in the RD marketing-fee programme.

Clients that relay errors into a human surface (chat, email, UI) should show `user_message` when present and fall back to `detail`. example: >- ACH payments pay out USD, so a USDC payout isn't possible on this rail.

Branch on `reason` rather than parsing `detail`. `detail` is unchanged. This is an open set: new values are added over time and a value is never repurposed, so treat an unrecognized `reason` as absent. Which operations return it today: - `createAccount` (onramp, offramp and swap) and `createTransaction` (a one-off transaction creates an account): every value in the table except `immutable_field`; `signature_required` comes from `createTransaction` only. - `updateAccount`: `field_invalid` (a developer fee that is out of range), `resource_not_found`, and `immutable_field` (the change would alter the account's routing; create a new account instead). - `deleteAccount`: `resource_not_found`. - `createInstructions`: a payment-agent instruction that creates an account fails with the same `reason` values as `createAccount`, but `params.field` is never returned there: the response carries the other `params` keys only, because this operation has no public field names to map to. - Other operations may also set `reason`. Treat a `reason` you do not recognize as absent, as above, and never assume an operation that is not listed here omits it. | `reason` | Meaning | `params` | | --- | --- | --- | | `field_required` | A required request field is missing. | `field` | | `field_invalid` | A field is present but unusable. | `field`, `constraint`, `rail` | | `field_too_long` | A field is longer than the rail allows. | `field`, `max`, `actual`, `rail` | | `field_too_short` | A field is shorter than the rail allows. | `field`, `min`, `actual` | | `address_incomplete` | An address lacks parts the route needs. | `subject`, `fields` | | `unsupported_network` | The network is not supported. | `network` | | `unsupported_asset` | The asset does not exist on the network. | `asset`, `network` | | `no_route_available` | No payment route covers the request. | `direction`, `rail`, `currency`, `network` | | `onboarding_required` | The customer has not completed onboarding for a capability. | `capability` | | `entity_not_active` | Onboarding for a capability exists but is not yet usable. | `capability`, `status` | | `destination_unreachable` | The destination cannot be reached over the requested rail. | `rail`, `alternative`, `direction` | | `limit_exceeded` | An amount exceeds a ceiling. | `limit`, `max`, `configured`, `currency` | | `resource_not_found` | The named resource does not exist. | `resource` | | `duplicate_resource` | A matching resource already exists. | `resource` | | `request_rejected` | The request was refused and the reason is not disclosed. | none | | `signature_required` | The request must be signed. | none | | `immutable_field` | The field cannot be changed on an existing account; create a new one. | none | example: field_too_long params: type: object description: | Parameters of `reason`.
