Overview
This node operation sends media messages (images or videos) via WhatsApp using the WARest WhatsApp REST API. It supports sending media either by URL, local path, base64 data URI, or directly from binary data within the workflow. Additional options include adding captions, compressing media, and sending view-once media. This node is useful for automating the distribution of multimedia content to WhatsApp contacts or groups, such as marketing images, product videos, or personal media sharing.
Use Case Examples
- Sending a promotional image with a caption to a customer list.
- Sharing a video clip to a WhatsApp group automatically.
- Sending a view-once photo for secure or temporary viewing.

| Binary File | Toggle to enable sending media from a binary property instead of a URL or path. |
| Media | URL, local path, or base64 data URI of the media to send (used if Binary File is false). |

Troubleshooting
- Ensure the session ID is valid and active; invalid sessions will cause failures.
- If using binary mode, verify the binary property name matches the input data.
- Check that the recipient phone number or JID is correctly formatted and reachable on WhatsApp.
- For view-once media, confirm the recipient's WhatsApp client supports this feature.
- Compression may reduce media quality; disable if quality is critical.
