Record a payment

Record money paid against a bill. The paid total is the sum of the payments, and the document becomes paid once they cover it.

Outcome

Record money paid against a bill. The paid total is the sum of the payments, and the document becomes paid once they cover it.

Before you start

Verify the intended environment, authenticated identity and specifically approved organization context.
The published application permission is bills:write. Discover the exact granted canonical Books workspace and bind it separately from action input.
Approve the actual mutation, accounting inputs and any provider/recipient effects before CLI --confirm or MCP confirm:true. Fixture identifiers and simulated provider responses authorize no live operation.

Discover the target

topolo whoami --json
topolo actions get app_topolo_books.bills.payments.record --detail --json
topolo resources topolo-books --json
topolo workspaces list topolo-books --json

Set BOOKS_WORKSPACE_ID to the exact granted workspace returned by discovery.
documentId: Exact document.id from invoices.list/get or bills.list/get, as appropriate to this action; the displayed invoice number is distinct.
bankLineId: Exact bank line.id from bank.lines.list in this workspace and bank account.

Request

POST /api/bills/{documentId}/payments

Inspect and test this action. Save the reviewed input as payload.json; supply credential/resource context separately.

Input fields

Field	Required	Meaning	Schema and constraints
`documentId`	Required	Exact document.id from invoices.list/get or bills.list/get, as appropriate to this action; the displayed invoice number is distinct.	{"type":"string","minLength":1}
`paidOn`	Required	paid On	{"type":"string","pattern":"^\d{4}-\d{2}-\d{2}$"}
`amountMinor`	Required	Currency minor units as a safe integer, not a decimal money string. Follow this action’s sign and minimum constraints.	{"type":"integer","exclusiveMinimum":0,"maximum":9007199254740991}
`reference`	Optional	reference	{"anyOf":[{"type":"string","maxLength":200},{"type":"null"}]}
`bankLineId`	Optional	Exact bank line.id from bank.lines.list in this workspace and bank account.	{"anyOf":[{"type":"string","minLength":1},{"type":"null"}]}

Inspect nested fields and the complete input schema.

Effects

Records money paid out. The paid total is the sum of the payments, and the bill becomes paid once they cover it.

Interpret the response

Read $.document.id for the returned bill identifier. Empty collections and nullable fields do not discover a target.

Call app_topolo_books.bills.get and check paid_minor and status.

Inspect the success schema. CLI/MCP add their own transport envelope; CLI --detail requests the full result.

Worked examples

Actual Books route handlers and the exported Worker were exercised against five local SQLite D1 concern databases with all committed migrations, the real posting Durable Object and local R2. Route captures use synthetic verified Auth; Worker captures use synthetic Auth transports. Nexus, Brand, Notify, Pay, Mercury and Xero responses are explicitly simulated at the provider transport boundary. Captures prove local request/response behavior and canonical SDK projection, not live bank access, payment movement, email delivery, provider eligibility, tax compliance, encrypted custody, scheduled execution, deployment or production completion. Fixture identities, credentials, addresses and records authorize no live operation.

Run a reviewed request

Save the input from the selected worked example as payload.json. Validate and inspect the plan before calling the action; refused examples demonstrate errors and are not instructions to execute.

CLI:

topolo actions validate app_topolo_books.bills.payments.record --data @payload.json --json
topolo actions plan app_topolo_books.bills.payments.record --resource-type workspace --resource-id "$BOOKS_WORKSPACE_ID" --data @payload.json --json
topolo actions call app_topolo_books.bills.payments.record --resource-type workspace --resource-id "$BOOKS_WORKSPACE_ID" --data @payload.json --confirm --detail --json

Errors and recovery

auth_error (HTTP 401): Authenticate in the intended organization again. Verify whoami and the exact Books application/workspace binding before retrying; do not switch identity to work around a refusal.

These are observed local refusals. Shared authentication, schema validation and resource authorization can also refuse before the route. Preserve the actual error, details and request id.

Recovery boundary

A recorded payment cannot be removed through the API yet. Check the amount before sending.

List bills: List bills newest first. Filter by status, contact or issue date, search the number, reference and notes, and sort by issue date, due date, number, total or status. The response carries the outstanding total for the filtered set.
