The synchronous method returns a JSON response, inclusive of information like documentUrl. This feature is advantageous for archiving the generated file's URL or for its subsequent manipulation in your application.


With the direct method, the PDF is directly transmitted to the client, facilitating an immediate file download. This is a practical approach when instant access to the generated PDF is required by the user.

Embracing the Asynchronous Method

For projects where a webhook is crucial for asynchronous operations, consider leveraging our asynchronous approach.

This method is a perfect fit for situations that demand webhook integration for processing tasks in the background. Ideal for handling bulk document processing, facilitating automatic real-time updates, or integrating PDF creation in a larger automated system, our asynchronous method guarantees efficiency and responsiveness, even with intricate or lengthy processes.
