List delivery events for a message
Returns the delivery-event timeline for one outbound send, newest first — the delivery, bounce, and complaint events observed after the message was accepted for delivery.
Returns the delivery-event timeline for one outbound send, newest first — the delivery, bounce, and complaint events observed after the message was accepted for delivery. Each event carries its type, the recipient, occurredAt, and the send's subject/from/to; a bounce adds bounceType, bounceSubType, bounceAction, bounceStatus, and diagnosticCode, and a complaint adds complaintFeedbackType, complaintSubType, and complaintUserAgent. limit defaults to 50 and is capped at 100; this list is not cursor-paginated. The same signals arrive live as the message.delivered, message.bounced, and message.complained webhook events. Requires the messages:read scope; see outbound tracking.
Scope: messages:read. Send the API key as a bearer token; Scopes lists what each one reaches.
