# card_statements.pay

## What it does

Record an evidenced partial or full repayment of a received card statement bill. Uses pay_card: Dr 2190 / Cr company cash; posts no expense and sends no money. The actual account overrides the contract default for a settled bill. After reversing a wrong payment, its replacement can keep the true payment date even if the reversal is later-dated.

## Before you send it

An authorized OAuth connection may call it, including a headless client. Effective membership, application grant and token permissions still apply. Describe `card_statements.pay` through `GET /v1/catalog/commands/{name}` before acting.

The envelope may reference a registered source document of kind `source_document`; this is separate from any evidence required by the input.

## Inputs

Put these fields inside the envelope's `input` object. The outer envelope names the command, a stable `idempotency_key` and `effective_at`; [request and recovery rules](/docs/api/) explain those separately. Use exact minor-unit integer strings for monetary fields. Take existing IDs from prior reads or command results; choose a new identity only where the command asks for one.

Required means required within its containing object; an optional parent can be omitted.

| Field | Type | Required | Meaning and accepted values |
|---|---|---|---|
| `statementId` | string | Yes |  Minimum length: `1`. |
| `financialAccountId` | string | Yes |  Minimum length: `1`. |
| `amount` | string | Yes |  Pattern: `"^[1-9][0-9]*$"`. |
| `effectiveAt` | string | Yes |  Format: date-time. |
| `sourceFactId` | string | Yes |  Minimum length: `1`. |
| `evidence` | array | Yes |  Items: object. Minimum items: `1`. Maximum items: `20`. |
| `evidence[].kind` | string | Yes |  Choose `"tap_message"`, `"x402_receipt"`, `"chain_tx"`, `"signed_doc"`, `"stripe_object"`, `"other"`. |
| `evidence[].ref` | string | Yes |  Minimum length: `1`. |
| `evidence[].signer` | string | No |  Minimum length: `1`. |

## After acceptance

When the command emits events, its documented effects and receipt are recorded in the command transaction. The response returns `commandId`, `replayed`, the command-specific `result` below and emitted `events` with their IDs and CIDs. A command is not automatically a cash movement or revenue recognition: use the behavior above to determine what this command records.

Inspect `result` and the affected records or reports before continuing. Save returned identifiers for later calls. Fetch `GET /v1/commands/{id}` with `commandId` to recover the accepted receipt; retry the same intent with the same idempotency key if the response was lost. Some commands can succeed with `events: []` and return a transient result and `commandId` without persisting a receipt. A lookup of that ID can return null; retain the returned result and verify the affected record. Retrying can re-evaluate the current state rather than replay a stored result. A domain `no_change` is a separate success outcome with no persisted receipt.

### Result fields

Required means required within its containing object; an optional parent can be omitted.

| Field | Type | Required | Meaning and accepted values |
|---|---|---|---|
| `paymentId` | string | Yes |  Minimum length: `1`. |
| `statementId` | string | Yes |  Minimum length: `1`. |
