Every endpoint is Bearer-authenticated with a LazyApp API key, returns JSON, and is scoped to the workspace and mode (`live` or `test`) the key belongs to. Live keys need the Pro plan. A live key on a workspace below Pro gets `402` with `code: plan_limit_reached` on every request. Test keys work on every plan, so you can build against the test number before you upgrade. LazyApp adds 0% to Meta's message rates. Meta bills each message to the business's own Meta payment method; your LazyApp plan is billed separately. contact: name: LazyApp support url: https://lazyapp.in servers: - url: https://lazyapp.in description: Production security: - bearerAuth: [] tags: - name: Messages description: Send and schedule WhatsApp messages. - name: Contacts description: The people you message, and their identifiers. - name: Conversations description: Threads and their message history. - name: Calls description: WhatsApp call history for the workspace. - name: Templates description: Create, submit and sync message templates. - name: Media description: Upload, retrieve and delete media. - name: Broadcasts description: Template sends to many contacts at once. - name: Events description: Say what happened; LazyApp picks the template. - name: Flows description: WhatsApp Flows and their responses. - name: Webhooks description: Register endpoints and inspect deliveries. - name: Workflows description: Automations and their executions. - name: Verify description: One-time passcodes over WhatsApp. - name: Capabilities description: What each connected number supports. - name: Catalog description: Proxy Meta Commerce catalog products for a connection. - name: Platform description: Manage customers if you run a platform on LazyApp. - name: Meta-compatible proxy description: Drop-in endpoints for existing Cloud API integrations. - name: Connections description: >- Your WhatsApp numbers and the account behind them: health, limits, registration, display name, blue tick, QR codes, conversation starters, opt-in links, business profile and blocked users. - name: Billing description: >- Meta's message rates, which LazyApp passes on with 0% added, and the billing facts behind them. - name: Analytics description: Workspace messaging aggregates. - name: Groups description: WhatsApp group chats on a connection Meta has enabled. - name: Funding description: Local funding status and recorded WhatsApp charges. - name: Connections description: 'WhatsApp connections: block users, business profile, insights.' - name: Payments description: >- WhatsApp payments in India: ask for payment, follow it, update the order and refund. paths: /v1/messages/direct-send: post: tags: - Messages summary: Send without an approved template description: >- For numbers enrolled in Meta's direct-send programme. `category` must be `utility` or `authentication`; marketing is not eligible. **Required scope:** `messages:send` parameters: - name: Idempotency-Key in: header description: >- Optional.
