File Message

The File Message component lets you attach files to a message that can be sent to other parts of your workflow. It’s useful when you need to send documents, images, or any other file along with a text note.

How it Works

When you drop this component into your dashboard, you can type a short text note and then attach one or more files. The component bundles the text and the files into a single Message object. That object can then be passed to other components, such as a messaging service or a storage system, without any extra steps.

Inputs

  • Text: The plain text you want to include in the message.
  • Message with files: A set of files that you want to attach.
  • Audio Video Encoder: An optional encoder that can process audio or video files before they are attached.

Outputs

  • Message: A single object that contains the text and all attached files. This output can be used by downstream components that expect a message payload.

Usage Example

  1. Drag the File Message component onto your canvas.
  2. In the Text field, type “Here are the reports for Q3.”
  3. Click the Message with files input and select the PDF and Excel files you want to send.
  4. (Optional) Connect an Audio Video Encoder if you need to compress or transcode any media files.
  5. Connect the Message output to the next component in your workflow, such as an email sender or a cloud storage uploader.
  6. Run the workflow – the message, complete with attachments, will be delivered to the next step.
  • Text Message – Sends plain text without attachments.
  • File Upload – Allows users to upload files from their device.
  • Audio Video Encoder – Processes media files before they are attached.

Tips and Best Practices

  • Keep the text short and clear; long messages can be hard to read in some interfaces.
  • Verify file sizes before attaching; large files may cause timeouts or exceed storage limits.
  • Use the Audio Video Encoder when sending media to reduce bandwidth usage.
  • Test the component with a small set of files first to ensure the output format matches what downstream components expect.

Security Considerations

  • Only attach files from trusted sources to avoid malware.
  • If the workflow sends messages to external services, ensure that file permissions are set correctly to prevent unauthorized access.
  • Consider encrypting sensitive files before attaching them, especially if they contain personal or confidential data.
