Each company gets at most 25 notices a minute, so a large send takes minutes. A reply from an end user is a normal chat turn and bills as one. `idempotency_key` (1 to 200 characters) is new for each notification: a request repeated with the same key returns the first notification and sends nothing again. `400` with what to change when the workspace has no active end-user Teams app, another notification is still sending, or the request is out of bounds. `429` after 20 new sends in an hour. Needs an admin or owner, or a member an admin gave the Send end-user notifications permission, else `403 insufficient_scope`. A triggered or scheduled agent run, with no person behind it, gets `403` too. ## OpenAPI ````yaml https://api.neoagent.io/public-api/openapi.json post /public-api/end-user-notifications openapi: 3.1.0 info: description: >- Neo's public contract for the dashboard ChatAgent, partner integrations, and MSP automation. Every response is wrapped in a `{data, meta}` envelope; errors use `{error: {code, message, details?}, meta: {request_id}}`. Authenticate with a `Bearer neo_sk__` API key (service account) or a Microsoft Entra ID JWT (dashboard user). Signed-URL endpoints (end-user feedback links) take a `signature` query parameter instead. title: Neo Public API version: 1.0.0 servers: - url: https://api.neoagent.io security: [] tags: - description: Service metadata — health, OpenAPI. name: Meta - description: Agents and workflows — read, version history, delete, stats. name: Agents - description: Agent/workflow execution history, sub-resources, retry/cancel. name: Executions - description: >- Every tool call the tenant's agents made in the last 30 days, within the caller's workflow access. name: Audit Log - description: PSA webhook events and their workflow-match results. name: Callbacks - description: Technician-in-the-loop approval requests. name: TIL requests - description: RMM script executions triggered by agents. name: RMM scripts - description: Dispatch-agent field-update decisions. name: Dispatch - description: The authenticated tenant. name: Tenant - description: Agent-builder schema catalogs (raw JSON payloads). name: Schemas - description: Escalate to the Neo team (HubSpot ticket). name: Escalation - description: Tenant settings. name: Settings - description: Tenant API-key management (dashboard JWT only). name: API keys - description: End-user feedback links (signed-URL auth). name: Feedback - description: End-client companies (CRUD + bulk-update). name: End companies - description: Channels — bind a CONVERSATIONAL agent to a transport (Teams or Slack). name: Channels - description: PSA/RMM/M365 integration status and connection management. name: Integrations - description: Technician roster (controls TIL routing and paging). name: Technicians - description: Future runs queued for TRIGGERED agents. name: Scheduled work - description: Subscription state and customer-facing credit usage (no provider $). name: Billing - description: Inbox messages and announcements. name: Inbox & Comms - description: Tenant-authored agent skills (CRUD) and the built-in skill catalog. name: Skills paths: /public-api/end-user-notifications: post: tags: - End-user notifications summary: Send a notification to end users description: >- Queues one message to many end users through the workspace's end-user Teams app, and returns at once with `state` `QUEUED`; read progress with `GET /public-api/end-user-notifications/{id}`. `end_company_ids` null sends to everyone the app reaches (as the reach with no companies). `recipients` is `"all"` or the `user_id`s from the reach with `include_people=true`; a picked person the app cannot reach is recorded `NOT_REACHABLE`, and a pick with more than 50 such people is refused with `400`. `message` is markdown, up to 4,000 characters.
