Existing slots are deleted and replaced with the provided list. Useful for bulk synchronization from external systems. Atomic: every slot is validated first (each needs `slotnummer` and `cases`; invalid rows are rejected with `400` and nothing is written), then the old slots are replaced in a single transaction. ## OpenAPI ````yaml put /v1/agents/{agentId}/forwarding-slots openapi: 3.1.0 info: title: TalkPilot API version: 1.0.0 description: > The TalkPilot API allows you to programmatically manage your call center agents, employees, forwarding slots, knowledge base, and more. ## Authentication All API requests require an API key passed via the `X-API-Key` header: ``` X-API-Key: tp_live_abc123def456... ``` An API key can reach every organization its creator is a member of (see `GET /v1/organization`) and can be restricted to specific agents and permissions. Create and manage keys in the TalkPilot Dashboard under **Settings > API** (Dev-Admin only). ## Rate Limiting Default limits per API key: **60 requests/minute** and **1,000 requests/hour** (both enforced, both configurable per key). Rate limit headers are included in every response to a request authenticated with an API key (Dashboard JWT requests are not rate limited): - `X-RateLimit-Limit` — Max requests per minute - `X-RateLimit-Remaining` — Remaining requests in the current minute window - `X-RateLimit-Reset` — Unix timestamp roughly 60 seconds in the future When rate limited, the API returns `429 Too Many Requests` with `Retry-After: 60` (minute window) or `Retry-After: 3600` (hour window). ## Pagination List endpoints support pagination via query parameters: - `page` — Page number (default: 1) - `limit` — Items per page (default: 20, max: 100) Paginated responses include a `pagination` object with `page`, `limit`, `total`, and `pages`. ## Error Format All errors follow a consistent format: ```json { "error": { "code": "VALIDATION_ERROR", "message": "Human-readable description", "details": [{ "field": "name", "message": "Required" }], "request_id": "req_abc123" } } ``` contact: name: TalkPilot Support email: support@talkpilot.io license: name: Proprietary identifier: LicenseRef-Proprietary servers: - url: https://api.talkpilot.io description: Production security: - apiKey: [] tags: - name: Health description: API health and status - name: Agents description: Manage AI agent configurations - name: Workflow description: Multi-state conversation flow of an agent - name: Tools description: Manage agent tools (HTTP requests, call transfers, etc.) - name: Employees description: Manage employees linked to agents - name: Contacts description: >- Customer contacts (customer_database) per agent — the voice agent recognises callers and greets them by name or tag from here - name: Forwarding Slots description: Manage call forwarding slot assignments - name: Knowledge Base description: Manage agent knowledge base documents - name: Calls description: Read call records and transcripts - name: Organization description: Organization-level settings - name: API Keys description: Manage API keys (Dashboard JWT auth only; dev_admin) paths: /v1/agents/{agentId}/forwarding-slots: put: tags: - Forwarding Slots summary: Replace all forwarding slots description: > Replaces all forwarding slots for an agent in a single operation.
