Setting the filename of the generated Document

When you generate a Document you might sometimes need to give it a specific name. To do so, you can provide the filename to use through the Document's meta-data:

{
  "_filename": "some-custom-name.pdf"
}

When calling the API, this should be sent using the meta property of the Document:

{
  "document": {
    "document_template_id": "...",
    "payload": "{ ... }",
    "meta": "{ \"_filename\": \"some-custom-name.pdf\" }"
  }
}
