Update Quote Line

PUT 
/api/quotes/:quote/lines/:line

Update a single quote line. All fields optional — send only what changed. Editing quantity/unit_price/discount recalculates the quote totals.

Required scope: orders:write

Grant this scope to your token under Settings → Developer → Personal Access Tokens.

Fields: quantity (numeric), unit_price (numeric), description (string|null), warehouse_id (int|null), discount_type (none|percentage|fixed_amount), discount_value (numeric|null), tax_rate_id (int|null, exists:tax_rates — per-line tax override).

Authentication: Requires Bearer token. Permission: quotes.update.

Successful response

401

Unauthenticated — the bearer token is missing, revoked, expired, or malformed. Never retry automatically; fix the credential. See the Errors guide.

403

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.

404

Not found — no record with the given identifier (or the route does not exist). Verify the ID before retrying.

422

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.

429

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.
