Source: https://cotlet.dev/docs/api/dext/update_item

Docs sections: [Get started](https://cotlet.dev/docs.md) · [REST API](https://cotlet.dev/docs/api.md) · [MCP](https://cotlet.dev/docs/mcp.md) · [SDKs & CLI](https://cotlet.dev/docs/sdks.md) · [Integrations](https://cotlet.dev/docs/integrations.md)

Change extracted fields of an item, such as supplier, category, date or total.

Dext API: https://cotlet.dev/docs/api/dext.md

`PATCH https://cotlet.dev/api/v1/dext/items/{item_id}`

Access: write.

Updates the fields you pass and leaves the rest. Dext moves an item to Ready once Category, Supplier and Total amount are filled. The change reaches no one and is undone with another update, so it runs without asking.

## Parameters

| Name | Type | Required | Description |
|---|---|---|---|
| `item_id` | string | yes | Item ID from list_items. |
| `supplier` | string | no | Supplier or customer name. |
| `category` | string | no | Category name as in Dext. |
| `date` | date | no | Document date. |
| `document_reference` | string | no | Invoice or receipt number. |
| `description` | string | no | Item description. |
| `total_amount` | number | no | Total amount including tax. |
| `tax_amount` | number | no | Tax amount. |
| `paid` | boolean | no | Paid toggle. |
| `payment_method` | string | no | Payment method name as in Dext. |
| `publish_to` | string | no | Publish destination, a connected accounting software. |
