Sirion (SirionLabs) is an AI-native enterprise Contract Lifecycle Management (CLM) platform. SirionOne manages the full agreement lifecycle - authoring, negotiation, e-signature, a searchable contract repository, metadata and clause extraction, obligation and performance management, and supplier / counterparty governance. The platform exposes REST "Business API & Integrations" capabilities plus pre-built connectors (Salesforce, SAP Ariba, SAP S/4HANA, DocuSign, iPaaS) and configurable webhooks, secured with OAuth 2.0 client credentials. API access is enterprise / contract-gated - credentials are provisioned per tenant and the API reference is available to authenticated Sirion users. Endpoint paths and schemas in this entry are MODELED from public product references, not copied from a public reference document.
