This article explains how Aspose.Words Java developers can create a fillable form in a DOCX document using the Aspose.Words Cloud REST API, and it covers the key parameters you can use to configure the form fields. For more information about the DOCX format, see the DOCX file info page.

Prerequisite

• Create an account and get API credentials
• Download Aspose.Words Cloud SDK for Java to create form fields
• Set up a Java project with the above SDK to add fillable forms

Steps to Make a Fillable Form in Word with Java REST API

1. Instantiate the WordsApi object with a client ID and secret for creating form fields
2. Load the target Word document into a file stream
3. Create a FormFieldTextInput object and set the properties of the form field
4. Create an InsertFormFieldOnlineRequest by setting the desired parameters
5. Call the InsertFormFieldOnline() method by providing the request object
6. Save the output Word file from the task result

The steps above show how to make a Word document fillable with the Java REST API. Begin by loading the source DOCX file and creating a FormFieldTextInput object with the required properties. Use this object to build the InsertFormFieldOnlineRequest and invoke InsertFormFieldOnline() to add the field to the document.

Code to Make a Form in Word with Java Low Code API

This sample demonstrates how to create a fillable form in Word using the Java Low Code API. By setting the nodePath (section 1, paragraph 3 using zero‑based indexes), you control where the fields are placed. After the fields are added online, the task result provides the output file.
