# Import data into PDF form using Web SDK with Document Engine

When you use [Nutrient Web SDK with Document Engine](https://www.nutrient.io/guides/web/about/operational-modes.md#nutrient-web-sdk-with-document-engine), the up-to-date form field values of a document are automatically imported when you open the document.

If you use [Instant](https://www.nutrient.io/guides/web/instant-synchronization.md), whenever any of the connected clients fills in the form field, the change is automatically synchronized to all the other connected clients.

Using Web SDK with Document Engine, you can also fill the form fields with values coming from any source — e.g. a database or your backend application — using Document Engine’s [forms API](https://www.nutrient.io/api/reference/document-engine/upstream/). For example, assuming there are form fields called `firstNameField` and `lastNameField` in the document, you can set their values using the following HTTP request:

### SHELL

```shell

curl -X POST http://localhost:5000/api/documents/your-document-id/form-field-values \
  -H "Authorization: Token token=<secret token>" \
  -H "Content-Type: application/json" \
  -d '{
  "formFieldValues": [
    {
      "name": "firstNameField",
      "value": "John"
    },
    {
      "name": "lastNameField",
      "value": "Appleseed"
    }
  ]
}'

```

### HTTP

```http

POST /api/documents/your-document-id/form-field-values HTTP/1.1
Content-Type: application/json
Authorization: Token token=<secret token>

{
  "formFieldValues": [
    {
      "name": "firstNameField",
      "value": "John"
    },
    {
      "name": "lastNameField",
      "value": "Appleseed"
    }
  ]
}

```

After the request succeeds, any [client opening that document from Document Engine](https://www.nutrient.io/guides/web/open-a-document/from-document-engine.md) will see that the form fields have these values. Moreover, any clients that are connected with [Instant](https://www.nutrient.io/guides/web/instant-synchronization.md) enabled will see the values update in real time.
