Create template (DOCX)

DOCX templates in ZapSign allow for the automation of documents with dynamic fields, facilitating the generation of contracts, agreements, and other recurring documents. Creating documents from a template is useful for various use cases, such as:

• Sending a document to the signer to complete a form, and using that information to create the document. Examples include insurance policy applications, informed consent forms, event registrations, and more.

• Sending the document to the signer partially filled out, allowing them to complete the form and fill in the missing fields. The document will be created, and the signer will proceed with the signing process. Examples include bank account openings and loan applications.

• Filling in all dynamic fields to create the final document, where the signer only needs to sign it. Examples include employment contracts, promissory notes, and lease agreements.

Creating the Document in Word (DOCX)

Before using the endpoint to create a template in ZapSign, you need to prepare the DOCX file with dynamic fields that will be replaced with specific information during each document generation. Follow these steps:

1. Create the Base Document

• Use Microsoft Word, Google Docs (exporting to DOCX), or any compatible DOCX editor.

• Draft the document content, ensuring it is properly structured.

2. Define Dynamic Fields

• Dynamic fields are represented with double curly braces {{field}} within the document.

• Example: {{name}}, {{date}}, {{email}}.

3. Avoid Images and Tables

• We recommend avoiding images and tables in the DOCX document, as they may interfere with the proper functionality.

4. Save and Export

• Save the file in .docx format.

• Verify that the dynamic fields are correctly written and placed.

Once the DOCX document is prepared, you can use the corresponding endpoint to upload the template to ZapSign and start generating documents automatically.

Next Steps

• If the signer needs to complete dynamic fields in the form during signing, you must configure the form using the "Template Form Configuration" endpoint.

To create documents from this template, go to the "Create Document via Template" section.

About Base64

Base64 is a simple way to convert files into text. If you want to learn more about what Base64 is, you can check out the full definition here. Converting a file to Base64 and sending it as text in the request body makes it easier to handle compared to formats like multipart/form-data.

To test the API, you can manually convert your DOCX file to Base64 using various online tools, such as this one.

Once the API is integrated into your system, look for the appropriate function in your programming language to convert files to Base64.

Important: you must send the base64_pdf parameter only with the base64 file conversion. Dont send the data:application/pdf;base64, on your parameter.
