Brella Events API

openapi: 3.0.3
info:
  title: Brella Integration API
  description: >-
    Public REST Integration API for the Brella event networking and engagement
    platform. Organizers use it to read event data - events, attendees, speakers,
    sponsors, timeslots (schedule), and invites - for a Brella organization and
    sync it to registration, CRM, and analytics tools. Access is gated: an
    organization admin generates an API key from the Brella admin panel and sends
    it in the Brella-Api-Access-Token header. Versioning is negotiated via the
    Accept header (application/vnd.brella.v4+json). Pagination is mandatory on all
    list endpoints (page[size] up to 500, page[number]). Only endpoints confirmed
    against the public developer portal (developer.brella.io) are modeled here;
    additional documented surfaces (RSVP & session check-in, statistics &
    analytics) exist but their exact paths were not confirmed at authoring time.
