Sirion Webhooks API

  title: Sirion CLM API (Modeled) Contract Requests Webhooks API
  description: 'IMPORTANT - MODELED DOCUMENT. This OpenAPI definition is a MODELED representation of the Sirion (SirionLabs) CLM "Business API & Integrations" surface. It is NOT copied from an official public reference. Sirion''s API reference is available only to authenticated Sirion users (via My Account -> Resources -> Help Guide in the tenant application, and at docs.sirion.ai behind login), and API access is provisioned per enterprise tenant.


    What is publicly CONFIRMED and reflected here: (1) SirionOne is RESTful and "any activity possible in the web application is possible via the APIs"; (2) authentication uses OAuth 2.0 client credentials for Sirion B2B APIs (an OAuth Client Id and OAuth Client Secret generated by a tenant admin under Admin 2.0 -> Business API & Integrations / OAuth Client Setup); (3) Sirion supports configurable outbound webhooks with field-based filtering and event-based, asynchronous processing; (4) core CLM entities include contracts, contract requests (CDRs), metadata and clauses, obligations, and suppliers / counterparties.


    What is MODELED and NOT publicly confirmable: all endpoint paths, the exact request/response schemas, the OAuth token URL, and the per-tenant host. The base server below uses a `tenant` variable on the confirmed product domain sirioncloud.com; substitute your organization''s actual Sirion host. Do not treat these paths as authoritative - obtain the real reference from your Sirion tenant.'
