## How can I upload a JSON file to my server?

While you cannot send a JSON file with HTTPUpload, you can send the JSON string with the API [SetHTTPFormField](/_articles/info/api/WebTwain_IO.md#sethttpformfield){:target="_blank"}.

Dynamic Web TWAIN sends an HTTP POST request to the server when doing an upload. The SetHTTPFormField() method is used to [add extra fields to the HTTP form](/_articles/faq/additional-form-fields.md){:target="_blank"}. Just like how you can add extra text information to the form, you can also add the JSON string to it.
