Get Session Event - BlobHub

Read one event of a session’s stream by its id. The session events page describes the record.

POST `/revisions/:id/data/query` (Command: `get_session_event`)

Request Body

Parameter	Type	Required	Description
`command`	string	Yes	Must be `get_session_event`.
`session`	string	Yes	The ID or alias of the session. It must belong to the route’s revision.
`id`	string	Yes	The event’s `id`, as List Session Events returns it.

Response

Parameter	Type	Description
`event`	object	The event record: `id`, `session_id`, `revision_id`, `created_at`, `type`, `source`, the block its type adds, and `expires_at`. See Record.

A deleted session is still served by id while its stream lasts, so the session.deleted event can be read by its id for 24 hours after the purge. An alias of a deleted session no longer resolves.

Errors

Status	Error	Cause
404	`not_found`	The session’s stream holds no event with that `id`, or retention has removed it.
403	`forbidden`	Missing read access, or `session` does not resolve to a session of the route’s revision.
