# Bulk Apply Transaction Payment to Selected Invoices

`POST /coa/api/v1/invoice/bulk-apply-payment`

Apply a single transaction payment to multiple selected invoices.

Supports two selection modes:
- Explicit invoice IDs (``invoice_ids``)
- Filter-based selection (``filters``) for "select all matching" behaviour

Reuses :meth:`MarkInvoicePaidView.apply_transaction_payment` so that
line-level payment splitting, FX gain/loss realisation, and transaction
cleanup are all respected.  A single ``DraftQueue`` is created when
approval is required.

## Request body

  - `transaction_id` integer, required
