Add a session

POST/v1/organization/{orgId}/sessions-workspace/events/{eventId}/sessions

US Region: https://public-api.sessionboard.com · EU Region: https://public-api-eu.sessionboard.com

Adds a session the organizer invited (a keynote, a panel, a break), accepted at once, with its speakers. A speaker is matched by email across the organization. Speakers count toward the plan's speakers per event (403 enterprise_only, upgrade: speakers). Sends nothing. Requires write:sessions. Refused for a key restricted to particular events. Also at POST /v1/sessions-workspace/events/{eventId}/sessions.
