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")),
  option.WithPublicKey(os.Getenv("TELNYX_PUBLIC_KEY")), // Required for client.Webhooks.Unwrap (webhook verification)
)

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, then retry the request (bounded 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")
  }
  return err // Propagate: a failed request must never look like success to the caller
}

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

Places the call into a queue, where it waits until it is removed or bridged to another leg. Queue behavior is configured through the request body.

`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 the queue it is currently waiting in. The call remains active and can be directed with further call commands.

`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

Returns a paginated list of participants in the specified conference, with support for filtering.

`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` (s
