Lower settings may make the voice sound more expressive but less predictable, while higher settings make it sound steadier but less emotional. - `voice_similarity_boost` (double, optional) — Range 0 to 1. Determines how closely the AI matches the original voice. Higher settings potentially including unwanted noise from the original recording. - `voice_optimise_streaming_latency` (integer, optional) — Range 0 to 4. Optimises streaming latency - `voice_style` (double, optional) — Range 0 to 1.

Defaults to `advanced`. - Allowed values: `standard`, `advanced` - `realistic_filler_words` (boolean, optional) — If enabled, the agent will be using realistic filler words (for example, "um"). - `is_transcript_disabled` (boolean, optional) — If set to true, conversations will not be transcribed. - `redact_pii` (boolean, optional) — Whether to redact personally identifiable information (PII) from transcripts, post-call webhooks, and internal logs. Redacted data includes credit card numbers, CVVs, expiration dates, social security numbers, names, email addresses, phone numbers, and physical addresses. - `synthesizer_filter_words` (list of any, optional) — Words or characters that the agent should not say. - `end_call_reasons_v2` (list of AgentEndCallReasonsV2Items, optional) — Custom conditions that trigger automatic call termination with per-reason closing message control. When both end_call_reasons and end_call_reasons_v2 are present, v2 takes precedence. - `voice_synthesizer` (enum, optional) — The engine used to synthesize voice. - Allowed values: `eleven_multilingual_v2`, `eleven_turbo_v2`, `eleven_turbo_v2_5`, `eleven_flash_v2`, `eleven_flash_v2_5`, `eleven_v3`, `eleven_v4`, `eleven_v4_turbo` - `global_audio_tags` (string, optional) — Free-form audio tags that apply to every utterance for the duration of a call. Tags are wrapped in square brackets and set a persistent voice character such as an accent or base mood. Only supported when voice_synthesizer is eleven_v3, eleven_v4, or eleven_v4_turbo. - `suppression_level` (double, optional) — Strength of Voice Isolation, from 0 to 1. Only takes effect when `noise_cancellation` is `advanced`. Defaults to `1` on create. See [how values map to Strength in the app](/call-configuration#strength). - `interruption_fade_out` (integer, optional) — Each frame is 20 ms. When you interrupt the bot, the volume slowly goes down to 0 over that many frames. For example, 5 translates to a 100 ms fadeout. - `voice_speed` (double, optional) — Adjust how fast or slow your agent will talk on the call. - `voice_volume` (double, optional) — Adjust how loud or quite your agent will talk on the call. - `min_words_to_interrupt` (enum, optional) — You can set how many words the human must speak before the AI will stop speaking and listening. - Allowed values: `0`, `1`, `2`, `3`, `4`, `5` - `prompt` (string, optional) — Add variables in curly brackets. For example, \{your-variable}. - `greeting_message` (string, optional) — The greeting message the agent will open the conversation with. You can add variables in curly brackets (for example, \{your-variable}). - `greeting_message_mode` (enum, optional) — Controls how the agent delivers the initial greeting. `human`: the agent waits for the human to speak first. `agent_static`: the agent speaks `greeting_message` once the call is established. `agent_dynamic`: the agent generates a greeting from the prompt and speaks it once the call is established. Note: `voicemail_message` requires this to be set to `human`. Changing away from `human` while `voicemail_message` is enabled will fail. - Allowed values: `human`, `agent_static`, `agent_dynamic` - `greeting_message_human_talk_timeout` (integer, optional) — The maximum number of seconds the agent waits for the human to speak first when `greeting_message_mode` is set to `human`. If the human does not speak within this time, the agent will start the conversation automatically. - `llm` (enum, optional) — The LLM powering this agent. - Allowed values: `gpt-4.1`, `gpt-4.1-nano`, `gpt-4.1-mini`, `gpt-5-mini`, `gpt-5-nano`, `gpt-5.1`, `gpt-5.2`, `gpt-5.4`, `gpt-5.4-mini`, `gpt-5.4-nano`, `gpt-6-luna`, `synthflow`, `synthflow-premium` - `language` (enum, optional) — This agent's language.

To retrieve voice IDs, use the Get voices endpoint. - `fallback_provider` (enum, optional) — The provider for the fallback voice (elevenlabs, deepgram, or synthflow). - Allowed values: `elevenlabs`, `deepgram`, `synthflow` - `fallback_model` (string, optional) — The model to be used by the fallback provider. - `end_call_reasons` (list of string, optional, deprecated) — Deprecated: use end_call_reasons_v2 instead. Custom conditions that trigger automatic call termination (simple string array format). Works with both simple prompt and Flow Designer agents. ### AssistantsModelIdPutResponsesContentApplicationJsonSchemaResponse - `model_id` (string, optional) — Agent ID. You can find it on the agent’s page in your dashboard. ### AssistantsModelIdPutResponsesContentApplicationJsonSchemaDetails - `phone` (string, optional) — The phone number attached to the agent. - `voice` (string, optional) — The agent's voice. ### AssistantsModelIdPutResponsesContentApplicationJsonSchemaDetail - `status` (string, required) - `description` (string, required) - `request_id` (string, required) - `category` (string, required) ### CallTimeWindow Calling window evaluated in the agent's timezone. Recipients that come up while the window is shut wait for it to open. This does not replace the agent's working hours, which are checked separately when the call is placed, so a window that falls outside them fails every call. When neither is configured, recipients are dialed at any time. - `enable` (boolean, optional) — Whether the window is enforced. Defaults to true when `weekly_hours` is provided. - `weekly_hours` (map from string to list of CallTimeWindowWeeklyHoursItems, optional) — Keys are lowercase weekday names (`monday` to `sunday`). Each day holds a list of windows in `HH:MM` 24-hour format with `start` earlier than `end`. A missing or empty day means no calls on that day. ### AgentBackgroundNoise Add background noise to make the call more natural. - `enabled` (boolean, optional) — If enabled, the agent will add background noise. - `type` (enum, optional) — What kind of background noise should be present. - Allowed values: `cafe`, `office` - `volume` (integer, optional) — How loud the background noise should be. ### AgentEndCallReasonsV2Items - `reason` (string, required) — The condition that triggers call termination. - `closing_message_mode` (enum, optional) — Controls how the farewell message is generated. static: message is spoken verbatim. prompt: message is an instruction to the LLM. none: LLM generates its own farewell. - Allowed values: `static`, `prompt`, `none` - `closing_message` (string, optional) — The closing message content. Interpretation depends on closing_message_mode. ### CallTimeWindowWeeklyHoursItems - `start` (string, optional) - `end` (string, optional) ## Examples **Request** ```json { "name": "Cindy", "agent": { "noise_cancellation": "advanced", "llm": "gpt-4.1-Mini", "language": "multi" } } ``` **Response** ```json { "status": "ok", "response": { "model_id": "1726005822670x239735712159542050" }, "details": { "phone": "", "voice": "" } } ``` **SDK Code** ```python import requests url = "https://api.synthflow.ai/v2/assistants/1726005822670x239735712159542050" payload = { "name": "Cindy", "agent": { "noise_cancellation": "advanced", "llm": "gpt-4.1-Mini", "language": "multi" } } headers = { "Authorization": "Bearer ", "Content-Type": "application/json" } response = requests.put(url, json=payload, headers=headers) print(response.json()) ``` ```go package main import ( "fmt" "strings" "net/http" "io" ) func main() { url := "https://api.synthflow.ai/v2/assistants/1726005822670x239735712159542050" payload := strings.NewReader("{\n \"name\": \"Cindy\",\n \"agent\": {\n \"noise_cancellation\": \"advanced\",\n \"llm\": \"gpt-4.1-Mini\",\n \"language\": \"multi\"\n }\n}") req, _ := http.NewRequest("PUT", url, payload) req.Header.Add("Authorization", "Bearer ") req.Header.Add("Content-Type", "application/json") res, _ := http.DefaultClient.Do(req) defer res.Body.Close() body, _ := io.ReadAll(res.Body) fmt.Println(res) fmt.Println(string(body)) } ``` ```ruby require 'uri' require 'net/http' url = URI("https://api.synthflow.ai/v2/assistants/1726005822670x239735712159542050") http = Net::HTTP.new(url.host, url.port) http.use_ssl = true request = Net::HTTP::Put.new(url) request["Authorization"] = 'Bearer ' request["Content-Type"] = 'application/json' request.body = "{\n \"name\": \"Cindy\",\n \"agent\": {\n \"noise_cancellation\": \"advanced\",\n \"llm\": \"gpt-4.1-Mini\",\n \"language\": \"multi\"\n }\n}" response = http.request(request) puts response.read_body ``` ```java import com.mashape.unirest.http.HttpResponse; import com.mashape.unirest.http.Unirest; HttpResponse response = Unirest.put("https://api.synthflow.ai/v2/assistants/1726005822670x239735712159542050") .header("Authorization", "Bearer ") .header("Content-Type", "application/json") .body("{\n \"name\": \"Cindy\",\n \"agent\": {\n \"noise_cancellation\": \"advanced\",\n \"llm\": \"gpt-4.1-Mini\",\n \"language\": \"multi\"\n }\n}") .asString(); ``` ```csharp using RestSharp; var client = new RestClient("https://api.synthflow.ai/v2/assistants/1726005822670x239735712159542050"); var request = new RestRequest(Method.PUT); request.AddHeader("Authorization", "Bearer "); request.AddHeader("Content-Type", "application/json"); request.AddParameter("application/json", "{\n \"name\": \"Cindy\",\n \"agent\": {\n \"noise_cancellation\": \"advanced\",\n \"llm\": \"gpt-4.1-Mini\",\n \"language\": \"multi\"\n }\n}", ParameterType.RequestBody); IRestResponse response = client.Execute(request); ``` ```swift import Foundation let headers = [ "Authorization": "Bearer ", "Content-Type": "application/json" ] let parameters = [ "name": "Cindy", "agent": [ "noise_cancellation": "advanced", "llm": "gpt-4.1-Mini", "language": "multi" ] ] as [String : Any] let postData = JSONSerialization.data(withJSONObject: parameters, options: []) let request = NSMutableURLRequest(url: NSURL(string: "https://api.synthflow.ai/v2/assistants/1726005822670x239735712159542050")! as URL, cachePolicy: .useProtocolCachePolicy, timeoutInterval: 10.0) request.httpMethod = "PUT" request.allHTTPHeaderFields = headers request.httpBody = postData as Data let session = URLSession.shared let dataTask = session.dataTask(with: request as URLRequest, completionHandler: { (data, response, error) -> Void in if (error != nil) { print(error as Any) } else { let httpResponse = response as?
