Retrieve an Event Attachment

GET /api/0/projects/{organization_id_or_slug}/{project_id_or_slug}/events/{event_id}/attachments/{attachment_id}/

Retrieve metadata for a single attachment on an event, or download its contents by passing the download query parameter.

Requires the event-attachments organization feature.

Path Parameters

organization_id_or_slug (string) REQUIRED: The ID or slug of the organization the resource belongs to.
project_id_or_slug (string) REQUIRED: The ID or slug of the project the resource belongs to. Project slugs are unique within each organization.
event_id (string) REQUIRED: The ID of the event. It is a 32-character hexadecimal string as reported by the client.
attachment_id (string) REQUIRED: The numeric ID of the attachment, as returned from the attachments list endpoint.

Query Parameters:

download (string): If this parameter is present, the response will be a binary file download instead of JSON metadata. The value does not matter — any value (including empty) triggers the download. Depending on where the attachment is stored, the response may be a redirect to the storage service, so clients must follow redirects.
