Overview

The "View Attachment" operation in the Attachments resource allows users to retrieve a specific attachment by its unique identifier. This node is useful when you need to access or download a particular file attached to an entity within a system, such as a project management tool or document repository.

Practical examples include:

• Downloading a project-related document for review.
• Accessing an image or PDF attached to a task or issue.
• Retrieving logs or reports stored as attachments for further processing.

Properties

Output

The node outputs the data of the requested attachment. The json output field typically contains metadata about the attachment such as its id, name, size, and possibly other descriptive fields depending on the API response.

If the attachment includes binary data (e.g., a file), the node may also output this as binary data, allowing subsequent nodes to process or save the file.

Dependencies

• Requires an API key credential to authenticate with the external service hosting the attachments.
• The base URL for the API must be configured in the node credentials.
• The node depends on an OpenAPI specification to define its properties and requests.

Troubleshooting

• Invalid Id: If the provided attachment id does not exist, the node will likely return an error indicating that the attachment was not found. Verify the id is correct.
• Authentication Errors: Missing or invalid API credentials will cause authentication failures. Ensure the API key or token is correctly set up.
• Network Issues: Connectivity problems to the API endpoint can cause timeouts or connection errors.
• Permission Denied: Insufficient permissions for the API user may prevent access to certain attachments.

Links and References

• Refer to the external service's API documentation for details on attachment retrieval endpoints.
• Consult n8n documentation on how to configure API credentials and handle binary data in workflows.
