Overview

This node interacts with the Wassenger WhatsApp API, enabling automation and management of WhatsApp-related resources. Specifically, for the Files resource with the Get File Preview operation, it retrieves a preview of an outbound file by its ID. This is useful when you want to programmatically access or display a preview of files sent via WhatsApp through Wassenger, such as images, documents, or other media.

Practical examples include:

Automatically fetching and displaying previews of files sent in WhatsApp campaigns.
Integrating file previews into dashboards or CRM systems to provide quick access without downloading full files.
Validating or auditing outbound files before sending or processing further.

Properties

Name	Meaning
File ID	The unique identifier of the outbound file to retrieve a preview for. This must be a valid file ID from the Wassenger system.

Output

The node outputs JSON data representing the file preview information retrieved from the Wassenger API. This typically includes metadata about the file preview such as URLs, thumbnails, or preview content details depending on the API response.

If the file contains binary data (e.g., image or document preview), the node may also output this as binary data attached to the item, allowing downstream nodes to process or save the preview content.

Dependencies

Requires an active connection to the Wassenger WhatsApp API.
Needs an API key credential configured in n8n to authenticate requests.
The node depends on the Wassenger API's availability and correct permissions to access outbound files.

Troubleshooting

Invalid File ID: If the provided File ID does not exist or is incorrect, the node will likely return an error indicating the file was not found. Verify the File ID is correct and corresponds to an existing outbound file.
Authentication Errors: Missing or invalid API key credentials will cause authentication failures. Ensure the API key is correctly set up in n8n credentials.
API Rate Limits or Downtime: If the Wassenger API is rate-limited or temporarily unavailable, the node may throw errors or time out. Retry after some time or check API status.
Permission Issues: Insufficient permissions on the API key might prevent access to file previews. Confirm that the API key has the necessary scopes.
