This API provides endpoints for managing packages, documents, elements, stakeholders, and signing processes within the NSEV platform. ## Authentication This API supports multiple authentication methods: ### Basic Authentication Traditional HTTP Basic Authentication using username and password. ### OAuth 2.0 **Client Credentials Flow (Machine-to-Machine)** - Full API access including administrative endpoints - Ideal for server-to-server integrations **Authorization Code Flow (User-based)** - Limited API access excluding administrative endpoints - Ideal for user-facing applications - Supports delegated user access scenarios ## API Variants This specification is available in two variants: - **Full API**: Complete API with all endpoints (BasicAuth + OAuth2 M2M) - **User API**: Limited API excluding admin endpoints (OAuth2 user-based only) Administrative endpoints (`/poisonqueue`, `/absenceperiods`, `/auditproofs`) are restricted to machine-to-machine authentication only. ## Versioning This API follows semantic versioning principles. Major version changes may introduce breaking changes, while minor and patch versions maintain backwards compatibility. servers: - url: '{baseUrl}/esig/webportalapi/v4' variables: baseUrl: default: https://your-tenant.sign.gonitro.com description: >- Your tenant-specific base URL, including scheme and host (e.g. https://acme.sign.gonitro.com). Each NSEV customer has a unique URL. Replace this with yours before sending a request.
