# Document types

Choose a GETS document type for your country. This reference lists available bases and shows how UAE invoice and credit-note selections differ.

Set `country` and `documentType` in your [Unify submission](https://docs.complyance.io/api-reference/unify/submit-and-retrieve/). The `base` names the document category. Its availability depends on the country; a [modifier or variant](https://docs.complyance.io/api-reference/gets/base-and-modifiers/) can change the fields and treatment. A selected document type does not replace the invoice data in `payload`.

## Base choices by country

These are the base values each country accepts. Not every modifier or variant works with every base: [Choices by country](https://docs.complyance.io/api-reference/gets/base-and-modifiers/#choices-by-country) lists each country’s modifiers and variants and the combinations it rejects.

| `country` | Available `documentType.base` values |
| - | - |
| `AE` — United Arab Emirates | `tax_invoice`, `credit_note` |
| `SA` — Saudi Arabia | `tax_invoice`, `credit_note`, `debit_note`, `simplified_invoice`, `simplified_credit_note`, `simplified_debit_note` |
| `OM` — Oman | `tax_invoice`, `credit_note`, `debit_note`, `simplified_invoice`, `simplified_credit_note`, `simplified_debit_note` |
| `MY` — Malaysia | `tax_invoice`, `credit_note`, `debit_note` |
| `BE` — Belgium | `tax_invoice`, `credit_note`, `debit_note` |
| `DE` — Germany | `tax_invoice`, `credit_note`, `debit_note` |

To find the required fields for a base, open the country’s fields page, such as [UAE fields](https://docs.complyance.io/countries/ae/fields/). **Required fields by document type**, under the table, lists the mandatory and conditional paths for each base, modifier and variant. The **Table** view’s **Requirement** column summarises all document types; **Description** explains conditions and **Enums** lists fixed allowed values. Open **List with sample request** and choose the document type, modifiers and variant under **Scope** to see requirements and payload paths for that selection. A credit note can need a reason or a preceding-invoice reference that an invoice does not. Check the relevant [country fields](https://docs.complyance.io/api-reference/gets/country-extensions/) before sending one.

## UAE invoice and credit-note selections

The UAE offers two bases and no separate variant. For an ordinary document use `modifiers: []`; for out-of-scope or self-billed documents use the modifier shown here. These are **document selections**, not complete requests:

| Document | `base` | `modifiers` | UAE document type code |
| - | - | - | - |
| Ordinary tax invoice | `tax_invoice` | `[]` | `380` |
| Ordinary tax credit note | `credit_note` | `[]` | `381` |
| Out-of-scope commercial invoice | `tax_invoice` | `["out_of_scope"]` | `480` |
| Out-of-scope commercial credit note | `credit_note` | `["out_of_scope"]` | `81` |
| Self-billed tax invoice | `tax_invoice` | `["self_billed"]` | `389` |
| Self-billed tax credit note | `credit_note` | `["self_billed"]` | `261` |

For example, an ordinary UAE invoice starts with:

```json title="UAE invoice selection (excerpt)"
{
  "country": "AE",
  "documentType": {
    "base": "tax_invoice",
    "modifiers": []
  }
}
```

The [quickstart](https://docs.complyance.io/get-started/quickstart/) shows the full request and the `200` response. UAE credit notes require a credit-note reason; ordinary credit notes also require a preceding-invoice reference unless the reason is Volume Discount. See [UAE fields](https://docs.complyance.io/countries/ae/fields/) for conditions and allowed values. UAE debit notes are not available in this selection.

## If a type or field is rejected

Check the country row, then remove any modifier or variant that does not apply to that base. If the base is accepted but fields fail, compare the `getsPath` in each `422` error with the paths on the country’s fields page. For response details, see [Unify errors](https://docs.complyance.io/api-reference/unify/errors/).
