Any other owner action (posting a message, typing, reading messages) also extends the lease, so call heartbeat only when you have no other action to send but want to hold the claim. (vs escalationTyping, which also extends the lease but additionally shows the visitor a typing indicator.) ## OpenAPI ````yaml /openapi.yaml post /escalations/{id}/heartbeat openapi: 3.1.0 info: title: Flowyte V2 Control-Plane REST API version: 1.0.0 description: >- The single REST API for the Flowyte platform (base path `/api/v1`). Authenticate every request with a secret API key — `Authorization: Bearer flowyte_sk_…` — and each operation lists the scope the key must hold. Successful responses use the `ApiResponse` envelope; list responses use cursor-based `PaginatedResponse`. Errors are RFC 9457 problem+json. Streaming endpoints return Server-Sent Events (`event:\ndata:\n\n`, terminating with `event: done`). contact: name: Flowyte Platform license: name: Proprietary servers: - url: /api/v1 description: Flowyte control-plane (versioned URI; additive in v1). security: - apiKey: [] tags: - name: Agents description: The single user-facing entity. - name: Support description: In-app "Get help" form → support inbox email. - name: Skills description: > Agent capabilities / tools. A skill is ONE atomic action — typically a single API call the agent makes in one step (look up an order, create a record, send a message, transfer the call). Use a skill when the task is a single step. When a task needs several details gathered across turns BEFORE acting, build a Playbook (which gathers the inputs and then calls skills) — see the Playbooks tag. - name: Integrations description: Native OAuth integrations. - name: Knowledge description: RAG knowledge sources & preview. - name: Playbooks description: > Multi-turn conversation scripts — a node graph (gather → confirm → branch) the agent follows to collect several inputs IN ORDER across turns before acting. Build a playbook when a single skill call isn't enough because the agent must gather MANY details first, or run a SEQUENCE of skills, before it can finish (e.g. take a full service request: gather the problem, address, and time, confirm, THEN file it; qualify a lead; a multi-step intake). A playbook does NOT call an integration itself — it owns the conversation and holds the state across turns; the actual action is performed by the SKILL(s) it gathers the inputs for. So a playbook ORCHESTRATES skills. Rule of thumb — one API call → a Skill; "gather N things in order, then submit" → a Playbook that drives the conversation and calls the skill(s) at the end. - name: Variables description: > The agent-wide interaction-variable registry — DERIVED at read time from the agent's playbooks and skills (collect slots, skill output bindings, {var} placeholders) and merged with a thin annotation overlay (notes, declared type hints, manual declarations).

Texting is US-only; a number must be SMS-enabled and the org's 10DLC registration active before it can send. - name: Test description: Test, simulate, talk-token, probe. - name: Observe description: Post-call analytics, conversations, receipts, transcripts. - name: Billing description: Plans, wallet, usage, fixed phrases. - name: Voices description: Voice catalog. - name: ApiKeys description: Developer / API keys. - name: Webhooks description: Webhook endpoints & deliveries. - name: Records description: > Caller Context Store — pre-synced external records the agent greets a caller from, plus the learned object-type field registry.

This release dials informational campaigns only. - name: OAuth2 description: > Flowyte's minimal OAuth2 authorization server. The Flowyte Zapier app is the first registered client. The authorization-code grant (confidential client, optional PKCE) issues org-scoped SERVICE tokens (flowyte_oat_…) that ride the SAME scope matrix as an sk key. The public authorize/token/revoke endpoints are served at the ORIGIN ROOT (NOT under /api/v1 — see each path's `servers` override); consent + disconnect are /api/v1. paths: /escalations/{id}/heartbeat: parameters: - name: id in: path required: true description: The escalation session id whose lease to extend. example: esc_9f21 schema: type: string post: tags: - Escalation summary: Extend the claim lease description: > The pure keepalive: extend the owning key's activity-based lease (per-channel TTL) WITHOUT any other side effect — no spine write and nothing visible to the visitor.
