    No,Web APIs cannot receive files through JSON body. Files must be sent as binary or multipart/form-data. JSON is a text-based format that cannot encode binary file data, while files require binary transmission

    Can't we send file as base64 format in JSON body?
    Also can you guide how can I leverage multipart/form-data for sending file in Web API body, I am creating Web API in appian how do I have to pass the values in the body so that Appian can store the file?

    Yes, you absolutely can send files as base64 format in JSON body.

    I got your requirement now,
    Have you tried creating Web API by this option which will guide you easily.
