Update Bill Lines
PATCH/api/bills/:id/lines
Batch updates the lines of a bill. Replaces existing lines with the provided collection.
purchase-orders:writeGrant this scope to your token under Settings → Developer → Personal Access Tokens.
Authentication: Requires Bearer token.
Body:
- lines (required): Array of bill line objects
- lines.*.id (optional): Existing line ID (omit for new lines)
- lines.*.description: Line description
- lines.*.quantity: Quantity
- lines.*.amount: Unit amount
- lines.*.nominal_code_id (optional, nullable): The line's debit (expense/clearing) account. Send an explicit null to CLEAR the nominal code on the line (it persists as null). OMIT the field entirely to leave an existing line's code untouched. No inventory_control default is frozen onto the line — when the line carries no code, the GL debit is resolved at posting time from the bill's link_type (landed-cost bills linked to a purchase order / warehouse transfer / inbound shipment capitalize to the configured inventory_control account).
- lines.*.tax_rate_id: Tax rate ID (optional)

Response Headers
Unauthenticated — the bearer token is missing, revoked, expired, or malformed. Never retry automatically; fix the credential. See the Errors guide.
Forbidden — the token lacks a required scope, the endpoint is not available to API tokens, or the user behind the token lacks the permission. A human must adjust the token scopes or user permissions; do not retry.
Not found — no record with the given identifier (or the route does not exist). Verify the ID before retrying.
Validation failed — the body is a field → messages map (Laravel shape) or the platform envelope with a stable machine-readable code. Fix the payload and resubmit.
Rate limited — platform limit is 1,000 requests/min; individual tokens may carry lower limits. Honor the Retry-After header before retrying. See the Rate Limits guide.
