Owner restrictions apply. The API does not dial callbacks or alter in-app scheduling. scheduledAt is a UTC instant; contact timezone and source accompany it. Create with ownerId, contactId and scheduledAt; phoneNumber defaults to the contact. Requires an Idempotency-Key. ## OpenAPI ````yaml /api/openapi.json post /scheduled-calls openapi: 3.1.0 info: title: PowerDialer API v2 version: 2.0.0 description: >- Connect your CRM, sales workspace or reporting tools to PowerDialer using scoped API keys. Manage contacts and calling lists, read call evidence and analytics, and receive signed events. All example records and IDs are synthetic; replace them with values from your workspace. Shared-key v1 is retired. See /availability for verified release status and historical data coverage. Legacy outbound webhooks use a separate contract. servers: - url: https://api.migration.powerdialer.ai/api/public/v2 description: Production API v2; see /availability for verified release status. security: - ApiKey: [] tags: - name: Authentication - name: Workspace members - name: Contacts - name: Calling lists - name: Imports - name: Calls - name: Custom dispositions - name: Synchronization - name: Analytics - name: Webhooks - name: Webhook deliveries - name: Incoming webhook payloads - name: Scheduled calls description: Read and manage contact-linked scheduled callbacks. paths: /scheduled-calls: post: tags: - Scheduled calls summary: Create scheduled call description: >- Requires a contact attributed to the credential workspace: ScheduledCall has no workspace column, so unlinked or unattributed legacy records are excluded.

Requires an Idempotency-Key. operationId: postScheduledCalls parameters: - name: Idempotency-Key in: header required: true schema: type: string pattern: ^[A-Za-z0-9._:-]{1,200}$ description: >- Required. Omitting this header returns 400 `idempotency_key_required` and changes nothing; a value outside the pattern returns 400 `idempotency_key_invalid`. Persist one key for this logical operation before sending it. Reuse the same value only with the same method, path and body after a timeout. A changed request returns 409 idempotency_conflict; a matching retry returns the original response. example: 9d6b623c-c132-4d2f-b8cf-7c65d4760dbe requestBody: required: true content: application/json: schema: $ref: '#/components/schemas/ScheduledCallWrite' example: ownerId: user_example contactId: 123 scheduledAt: '2026-10-15T18:00:00Z' responses: '201': description: Scheduled call result. headers: X-Request-Id: schema: type: string format: uuid RateLimit-Limit: schema: type: integer RateLimit-Remaining: schema: type: integer Idempotency-Replayed: schema: type: string enum: - 'true' - 'false' content: application/json: schema: $ref: '#/components/schemas/ScheduledCall' example: id: 123 ownerId: user_example contactId: 123 phoneNumber: '+12125550100' scheduledAt: '2026-10-15T18:00:00.000Z' status: Pending notes: Call back callHistoryId: null createdAt: '2026-10-12T12:00:00.000Z' updatedAt: '2026-10-12T12:00:00.000Z' timeZone: America/New_York timeZoneSource: provided default: description: >- Error. 400 invalid request; 401 invalid credential; 403 insufficient access; 404 not found; 409 state/idempotency conflict; 413 size limit; 415 body not sent as application/json; 422 verification failure; 429 rate limit (Retry-After seconds); 503 temporary service failure. headers: Retry-After: schema: type: integer X-Request-Id: schema: type: string format: uuid content: application/json: schema: $ref: '#/components/schemas/Error' example: error: code: invalid_api_key message: API key is invalid, expired or revoked requestId: 00000000-0000-4000-8000-000000000004 x-codeSamples: - lang: bash label: cURL source: >- # Replace example resource IDs and ownerId with values from your workspace. : "${POWERDIALER_API_KEY:?Set POWERDIALER_API_KEY to your scoped API key}" # Set this once per operation; reuse it with the same request after a timeout. : "${POWERDIALER_REQUEST_ID:?Set POWERDIALER_REQUEST_ID to a new UUID for this operation}" curl --request POST \ --url 'https://api.migration.powerdialer.ai/api/public/v2/scheduled-calls' \ --header "Authorization: Bearer $POWERDIALER_API_KEY" \ --header "Idempotency-Key: $POWERDIALER_REQUEST_ID" \ --header 'Content-Type: application/json' \ --data '{ "ownerId": "user_example", "contactId": 123, "scheduledAt": "2026-10-15T18:00:00Z" }' components: schemas: ScheduledCallWrite: type: object properties: ownerId: type: string minLength: 1 maxLength: 100 contactId: type: integer minimum: 1 maximum: 2147483647 phoneNumber: type: string description: Optional E.164 number; defaults to the contact number. scheduledAt: type: string format: date-time description: UTC instant.
