How to Set Prefilled Values for Form Fields

BoldSign API makes signing easier by filling in form fields with prefilled values. This saves time for signers as they can quickly review and make any needed edits.

Supported form fields

Prefilled values can be set for the following form field types:

Textbox
Checkbox
Radio button
Image
Editable Date
Dropdown

Setting prefilled values

To set a prefilled value for a form field, you need to specify the value in the value property of the corresponding form field object.

Here are example codes you can use to do this:

Code snippet

curl -X 'POST' \
  'https://api.boldsign.com/v1/document/send' \
  -H 'accept: application/json' \
  -H 'X-API-KEY: {your API key}' \
  -H 'Content-Type: multipart/form-data' \
  -F 'Title="Sample Document"' \
  -F 'Signers={
  "name": "hanky",
  "emailAddress": "[email protected]",
  "signerType": "Signer",
  "signerRole": "Signer",
  "formFields": [
    {
      "id": "TextBox",
      "name": "TextBox",
      "fieldType": "TextBox",
      "pageNumber": 1,
      "bounds": {
        "x": 100,
        "y": 100,
        "width": 125,
        "height": 25
      },
      "isRequired": true,
      "value": "Prefilled Value"
    }
  ],
  "locale": "EN"
}' \
  -F 'Files={your file}' \

var documentClient = new DocumentClient(apiClient);

var documentFilePath = new DocumentFilePath
{
    ContentType = "application/pdf",
    FilePath = "{Your File path}"
};

var filesToUpload = new List<IDocumentFile>

};

    name: "David",
    emailAddress: "[email protected]",
    formFields: formFieldCollections,
    locale: Locales.EN);

In the above example, you have the flexibility to choose any supported field type and set a prefilled value using the value property for each field. Upon running the code, a document will be created with the specified values for the form fields.
