Invoice product fields

GET /v1/invoices/:id/products/fields

Returns descriptions of the fields on invoice product rows: names, types, and whether each field is readable and writable.

The discount amount is called discount — matching the data and the write contract. The previous name discountSum remains a deprecated alias: it is still returned by this endpoint and still accepted on write, so code written against the old field list keeps working. Product rows themselves carry only discount — migrate to it.

Parameters

Parameter Type Required Description
Parameterid (path) Typenumber Requiredyes DescriptionInvoice ID

Fielddata.<field>.type Typestring DescriptionValue type: integer, double, string, char
Fielddata.<field>.isReadOnly Typeboolean DescriptionRead-only: the field cannot be written
Fielddata.<field>.isRequired Typeboolean DescriptionRequired flag. false on every product-row field: a write accepts a row that carries at least one writable field
Fielddata.<field>.isImmutable Typeboolean Descriptiontrue on ownerId and ownerType: the row owner is set by the request path. Absent on priceAccount and xmlId

About id. An id supplied in PUT /v1/invoices/:id/products items does not guarantee the row's previous identifier: an unchanged row gets the same id even without this field, while a changed row gets a new one. For targeted editing, use PATCH /v1/invoices/:id/products/:rowId.

The schema is the same for every invoice. The response does not depend on the id in the URL: passing the ID of a nonexistent invoice returns the same schema and a 200 response rather than an error. This call cannot be used to check that an invoice exists — GET /v1/invoices/:id is there for that.

Error response example

403 — the key lacks the required scope:

JSON 
{

  "error": {
    "code": "SCOPE_DENIED",
    "message": "This endpoint requires 'crm' scope"
  }
}
