Direct TTS Broadcast

POST /api/broadcasts/direct-tts

Send a broadcast from plain text — the text is converted to speech (AI TTS) and played to each recipient. Processing is asynchronous: the API accepts the request, generates the audio in the background, then queues the calls.

Request Parameters

Parameter	Type	Required	Description
request_id	string	Yes	Unique request identifier (16-64 chars) to prevent duplicate requests. Use UUID or random string.
sender	string	Yes	Your active caller sender number (1-20 chars)
phone_numbers	array	Yes	Array of Bangladeshi phone numbers (01XXXXXXXXX format, 1-999 numbers). No duplicates allowed.
texts	array	Yes	Text strings (1-10, max 5000 chars each by default), converted to speech and played in order.
voice	string	No	`male` or `female` (default: provider default voice)
language_code	string	No	Language code, e.g. `bn-BD` (max 10 chars; default: account/provider default)
metadata	object	No	Custom data to associate with the broadcast.

Success Response Example

{
  "success": true,
  "message": "TTS broadcast request accepted, processing started",
  "data": {
    "request_id": "unique_direct_tts_001"
  }
}

The 202 response means the request was accepted, not that calls have started. Poll Get Direct TTS Broadcast Status with the same request_id until it is completed, then poll Get Broadcast Result for per-number call outcomes.
