description: 'ON24 (NYSE: ONTF) is a digital engagement and webinar platform that companies use to run webinars, virtual events,
  and always-on content experiences and to turn the resulting first-party engagement data into marketing and sales intelligence.
  ON24 publishes a complete, anonymously accessible OpenAPI 3.0.1 for its Webinar & Content Center (WCC) REST API v2 at https://api.on24.com/v2/openapi.json
  — 58 paths and 67 operations across six tags: Client Level Analytics, Event Level Analytics, Event Management, REST Registration,
  Content Listings and Helpers. Customers use it to automate registrant creation, pull attendee and engagement analytics into
  their CRM, marketing automation platform or data warehouse, provision and configure webinars, and honour GDPR erasure requests.
  The API runs from two regional hosts, https://api.on24.com/v2 (North America) and https://api.eu.on24.com/v2 (European Union),
  and is authenticated with a paired accessTokenKey / accessTokenSecret set of HTTP headers plus a numeric client id in every
  path. There is no OAuth surface, no first-party SDK and no MCP server, and rate-limit exhaustion is signalled as HTTP 403
  rather than 429.'

  note: 'Corrected 2026-08-13. The API contract itself is public (OpenAPI served anonymously at https://api.on24.com/v2/openapi.json),
    but CREDENTIALS are not self-serve: ON24 documents that the customer contract must include the "Connect" product before
    an API token can be provisioned, and a subset of operations additionally requires the Elite tier. No pricing is published.'
