# Creates a bill payment

`POST /bills/{bill_id}/payments`

## Request

- Base URL: `https://api.rillet.com`
- URL: `https://api.rillet.com/bills/{bill_id}/payments`
- Auth: HTTP bearer
- TypeScript: <https://skmtc.dev/rillet/apis/rillet-accounting-api/docs/bills/:bill_id/payments/post.ts> (a function with typed inputs; its response is checked against the schema)

Books a cash or scheduled disbursement that settles all or part of a bill, updating the outstanding payable and linking treasury activity.
Provide funding source details consistent with your configured payment rails so downstream bank reconciliation stays accurate.

IMPORTANT: Notice this operation has a redundancy between the `bill_id` path parameter and the `billId` attribute in the request body, which takes precedence and is used in internal logic. When executing this operation, both IDs must match, otherwise the request will be rejected. This is a legacy redundancy and will be removed in future versions of this operation.
