Extending the expiry date makes a package that had already expired available again. Documents within the package always expire on the same date as the package. The request body is the new expiry date as an ISO 8601 date-time value. ## OpenAPI ````yaml /nsev/api-reference/openapi.yaml put /packages/{packageId}/expirydate openapi: 3.0.0 info: title: NSEV WebPortal API version: 4.0.0 contact: name: NSEV Support Team url: https://connectivegroup.my.site.com/s/contactsupport?language=en_US description: > **Nitro Sign Enterprise Verified (NSEV) WebPortal API Version 4** A comprehensive digital signing API that enables secure document signing workflows. 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.
