Sync follows all provider pages and imports templates that do not yet exist locally. Draft updates remain local. On editable provider templates, only component or category changes are sent to Meta; parameter mappings and opt-out configuration remain local. Submit returns the provider-controlled review status. Send supports text headers/body plus static quick-reply, URL, phone and call-permission components; templates requiring runtime media, location, dynamic-URL or copy-code values are rejected locally. **Required scope:** `assistants:write`. Requires WhatsApp text in the workspace plan. ## OpenAPI ````yaml /api-reference/openapi.json post /whatsapp/templates openapi: 3.1.0 info: title: Famulor API version: 1.0.0 description: >- REST API for Famulor. Authenticate with an API key (`fam_...`, created under **Settings → API Keys**) or an OAuth 2.0 access token (`fam_at_...`) as a Bearer token. Every response uses a consistent envelope: `{ "data": ... , "meta": { ... } }` on success and `{ "error": { "code", "message" } }` on failure. List endpoints paginate with `?limit=` (default 50, max 200) and `?offset=`; `meta.pagination.total` carries the total match count. REST operations require API Access through the workspace plan or a recurring add-on. Without it, regular operations return `403 api_access_required`. The invoice-payment and billing-portal operations remain available with a valid `billing:write` credential after a failed plan payment so an authorized owner, admin, or billing member can recover billing. The same customer-facing capabilities are available as MCP tools at `https://app.famulor.io/mcp` (Model Context Protocol, streamable HTTP) using the same credentials, scopes, and workspace access. MCP availability is controlled separately by Connect AI / MCP, not by API Access. servers: - url: https://app.famulor.io/api/v1 description: Hosted platform. - url: https://{domain}/api/v1 description: White-label tenant domain — same paths, tenant branding. variables: domain: default: app.famulor.io description: Your white-label tenant domain. security: - bearerAuth: [] tags: - name: Account description: Self-inspection of the calling credential. - name: Migrations description: Preview and import data from supported legacy platforms. - name: Assistants description: Create and manage voice assistants. - name: Tools description: >- Reusable tools (HTTP APIs and external MCP servers) assistants can call mid-conversation. - name: Voices description: Browse the text-to-speech voice library. - name: Calls description: Start outbound calls and read call history, transcripts and recordings. - name: History description: Unified conversation history across calls, messaging and assistant emails. - name: Campaigns description: Outbound calling campaigns with a compliant power dialer. - name: Leads description: Manage Audience contacts across campaigns, channels and Call QA metrics. - name: Segments description: >- Saved, dynamic lead filters — reusable audience definitions used for Audience search and campaign lead assignment. - name: Suppression description: Cross-channel marketing opt-outs and active workspace suppression records. - name: Callbacks description: >- Scheduled callbacks booked by the Schedule callback tool across voice, chat, and email. - name: Phone Numbers description: Marketplace numbers and customer-provided numbers. - name: Famulor Loop description: >- Personal business-phone access, directory, presence, devices, and Loop call recents. - name: SIP Trunks description: Bring your own SIP provider and numbers. - name: Carrier Connections description: Connect a supported carrier account and import its existing phone numbers. - name: Knowledge Bases description: RAG knowledge bases and documents for assistants. - name: Settings description: Workspace-level settings such as caller-memory defaults. - name: Billing description: Balance and transaction ledger of the API key's workspace. - name: Automations description: >- Native workspace automations — list, create, update, trigger.

REST operations also require API Access for the credential's workspace. Keys can be restricted to scopes such as `assistants:read`, `calls:write`, `campaigns:write`, `automations:read`, `dashboards:read`, `dashboards:write`, `leads:write`, `segments:write`, `loop:read`, `loop:write`, `phone_numbers:write`, `sip_trunks:write`, `knowledge:write`, `voices:read`, `billing:read`, `billing:write`, `settings:write`, `platform:read`, `platform:write`; a `*:write` scope implies the matching `*:read`. Automation and dashboard endpoints also accept the legacy `calls:*` scope. Keys without scope restrictions have full access within the workspace's available capabilities. ```` This documentation is built and hosted on [Mintlify](https://mintlify.com), a developer documentation platform.
