Only the next available actor(s) in each workflow are notified. In a serial workflow, approvers, signers or form fillers who are still waiting for someone ahead of them to act do not receive a reminder. The call is processed asynchronously and returns a bulk action session identifier; poll the package bulk action session to follow its progress. ## OpenAPI ````yaml /nsev/api-reference/openapi.yaml post /packages/reminders/bulk 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. The esig path segment is required - the Web Application Firewall routes requests on it. security: - basicAuth: [] - bearerAuth: [] tags: - name: Configuration description: | Endpoints for retrieving system configuration settings, contact groups, templates and signing methods. - name: Packages description: | Core endpoints for creating, managing, and tracking packages throughout their lifecycle. - name: Documents description: | Endpoints for adding, removing, and managing documents within packages.
