Telnyx Voice Conferencing - Go

Installation

go get github.com/team-telnyx/telnyx-go

Setup

import (
  "context"
  "fmt"
  "os"

  "github.com/team-telnyx/telnyx-go"
  "github.com/team-telnyx/telnyx-go/option"
)

client := telnyx.NewClient(
  option.WithAPIKey(os.Getenv("TELNYX_API_KEY")),
)

All examples below assume `client` is already initialized as shown above.

Error Handling

All API calls can fail with network errors, rate limits (429), validation errors (422), or authentication errors (401). Always handle errors in production code:

import "errors"

result, err := client.Messages.Send(ctx, params)
if err != nil {
  var apiErr *telnyx.Error
  if errors.As(err, &apiErr) {
    switch apiErr.StatusCode {
    case 422:
      fmt.Println("Validation error — check required fields and formats")
    case 429:
      // Rate limited — wait and retry with exponential backoff
      fmt.Println("Rate limited, retrying...")
    default:
      fmt.Printf("API error %d: %s\n", apiErr.StatusCode, apiErr.Error())
    }
  } else {
    fmt.Println("Network error — check connectivity and retry")
  }
}

Common error codes: `401` invalid API key, `403` insufficient permissions, `404` resource not found, `422` validation error (check field formats), `429` rate limited (retry with exponential backoff).

Important Notes

• **Pagination:** Use `ListAutoPaging()` for automatic iteration: `iter := client.Resource.ListAutoPaging(ctx, params); for iter.Next() { item := iter.Current() }`.

Enqueue call

Put the call in a queue.

`POST /calls/{call_control_id}/actions/enqueue` — Required: `queue_name`

Optional: `client_state` (string), `command_id` (string), `keep_after_hangup` (boolean), `max_size` (integer), `max_wait_time_secs` (integer)

	response, err := client.Calls.Actions.Enqueue(
		context.Background(),
		"call_control_id",
		telnyx.CallActionEnqueueParams{
			QueueName: "support",
		},
	)
	if err != nil {
		log.Fatal(err)
	}
	fmt.Printf("%+v\n", response.Data)

Returns: `result` (string)

Remove call from a queue

Removes the call from a queue.

`POST /calls/{call_control_id}/actions/leave_queue`

Optional: `client_state` (string), `command_id` (string)

	response, err := client.Calls.Actions.LeaveQueue(
		context.Background(),
		"call_control_id",
		telnyx.CallActionLeaveQueueParams{},
	)
	if err != nil {
		log.Fatal(err)
	}
	fmt.Printf("%+v\n", response.Data)

Returns: `result` (string)

List conferences

Lists conferences. Conferences are created on demand, and will expire after all participants have left the conference or after 4 hours regardless of the number of active participants. Conferences are listed in descending order by `expires_at`.

`GET /conferences`

	page, err := client.Conferences.List(context.Background(), telnyx.ConferenceListParams{})
	if err != nil {
		log.Fatal(err)
	}
	fmt.Printf("%+v\n", page)

Returns: `connection_id` (string), `created_at` (string), `end_reason` (enum: all_left, ended_via_api, host_left, time_exceeded), `ended_by` (object), `expires_at` (string), `id` (string), `name` (string), `record_type` (enum: conference), `region` (string), `status` (enum: init, in_progress, completed), `updated_at` (string)

Create conference

Create a conference from an existing call leg using a `call_control_id` and a conference name. Upon creating the conference, the call will be automatically bridged to the conference. Conferences will expire after all participants have left the conference or after 4 hours regardless of the number of active participants.

`POST /conferences` — Required: `call_control_id`, `name`

Optional: `beep_enabled` (enum: always, never, on_enter, on_exit), `client_state` (string), `comfort_noise` (boolean), `command_id` (string), `duration_minutes` (integer), `hold_audio_url` (string), `hold_media_name` (string), `max_participants` (integer), `region` (enum: Australia, Europe, Middle East, US), `start_conference_on_create` (boolean)

	conference, err := client.Conferences.New(context.Background(), telnyx.ConferenceNewParams{
		CallControlID: "v3:MdI91X4lWFEs7IgbBEOT9M4AigoY08M0WWZFISt1Yw2axZ_IiE4pqg",
		Name:          "Business",
	})
	if err != nil {
		log.Fatal(err)
	}
	fmt.Printf("%+v\n", conference.Data)

Returns: `connection_id` (string), `created_at` (string), `end_reason` (enum: all_left, ended_via_api, host_left, time_exceeded), `ended_by` (object), `expires_at` (string), `id` (string), `name` (string), `record_type` (enum: conference), `region` (string), `status` (enum: init, in_progress, completed), `updated_at` (string)

List conference participants

Lists conference participants

`GET /conferences/{conference_id}/participants`

	page, err := client.Conferences.ListParticipants(
		context.Background(),
		"conference_id",
		telnyx.ConferenceListParticipantsParams{},
	)
	if err != nil {
		log.Fatal(err)
	}
	fmt.Printf("%+v\n", page)

Returns: `call_control_id` (string), `call_leg_id` (string), `conference` (object), `created_at` (string), `end_conference_on_exit` (boolean), `id` (string), `muted` (boolean), `on_hold` (boolean), `record_type` (enum: participant), `soft_end_conference_on_exit` (boolean), `status` (enum: joining, joined, left), `updated_at` (string), `whisper_call_control_ids` (array[string])

Retrieve a conference

Retrieve an existing conference

`GET /conferences/{id}`

	conference, err := client.Conferences.Get(
		context.Background(),
		"id",
		telnyx.ConferenceGetParams{},
	)
	if err != nil {
		log.Fatal(err
