Each call receives a unique ID and calculated schedule time. This endpoint is optimized for batch operations and campaign management. ## Bulk Operations Use this endpoint for: * **Campaign management**: Schedule multiple calls for marketing campaigns * **Batch notifications**: Send reminders or alerts to multiple recipients * **List processing**: Process contact lists efficiently ## Performance * Maximum recommended batch size: 1000 calls * All calls use the same agent configuration * Calls are processed and scheduled atomically ## OpenAPI ````yaml https://blackbox.dasha.ai/swagger/v1/swagger.json post /api/v1/calls/bulk openapi: 3.0.4 info: title: Dasha BlackBox Agent API description: API for managing AI agents and calls contact: name: DashaAI Team email: support@dasha.ai version: v1 servers: - url: https://blackbox.dasha.ai description: Dasha BlackBox Agent API security: - ApiKey: [] - OAuth: [] tags: - name: ActivityLogs - name: Agents - name: AgentTestCases - name: CallResults - name: Calls - name: Chats - name: Copilot - name: CustomerData - name: Mcp - name: Media - name: Misc - name: PronunciationDictionaries - name: Providers - name: SipAliases - name: SipCredentials - name: SipPhoneNumbers - name: TextChat - name: TwilioProvider - name: Voice - name: WebhookTest - name: WebIntegrations - name: WebSocket description: WebSocket endpoints for real-time communication paths: /api/v1/calls/bulk: post: tags: - Calls summary: Create bulk calls description: >- Schedules multiple outbound voice calls with an AI agent in a single request.
