Upload Asset to WebflowWEBFLOW_UPLOAD_ASSET
This tool allows users to upload assets (files, images, etc.) to a Webflow site. It involves a two-step process: first, generating a pre-signed Amazon S3 upload URL by calling the Webflow API, and second, uploading the file to that S3 URL. IMPORTANT: The file_content parameter must contain actual base64-encoded binary data, NOT a placeholder or variable reference. For example, 'SGVsbG8gV29ybGQh' is valid base64 that decodes to 'Hello World!'. The tool requires parameters such as site_id, file_name, file_content, md5, and optionally asset_folder_id to correctly upload and manage assets for the specified Webflow site.
