POST the file bytes to the returned upload_url as multipart form data under the field name 'file', then pass the returned attachment_id in the attachments array of POST /artifacts/{artifactId}/messages. The agent reads the file directly from its sandbox. Files live as long as the dashboard's sandbox (about 12 hours), so upload shortly before sending. ## OpenAPI ````yaml /api-reference/openapi.json post /v2/artifacts/{artifactId}/attachments/upload-urls openapi: 3.0.3 info: title: Duvo Public API description: >- Public API for programmatic access to Duvo.
