Telnyx Sip - 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() }`.

List all Access IP Ranges

`GET /access_ip_ranges`

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

Returns: `cidr_block` (string), `created_at` (date-time), `description` (string), `id` (string), `status` (enum: pending, added), `updated_at` (date-time), `user_id` (string)

Create new Access IP Range

`POST /access_ip_ranges` — Required: `cidr_block`

Optional: `description` (string)

	accessIPRange, err := client.AccessIPRanges.New(context.Background(), telnyx.AccessIPRangeNewParams{
		CidrBlock: "203.0.113.0/24",
	})
	if err != nil {
		log.Fatal(err)
	}
	fmt.Printf("%+v\n", accessIPRange.ID)

Returns: `cidr_block` (string), `created_at` (date-time), `description` (string), `id` (string), `status` (enum: pending, added), `updated_at` (date-time), `user_id` (string)

Delete access IP ranges

`DELETE /access_ip_ranges/{access_ip_range_id}`

	accessIPRange, err := client.AccessIPRanges.Delete(context.Background(), "access_ip_range_id")
	if err != nil {
		log.Fatal(err)
	}
	fmt.Printf("%+v\n", accessIPRange.ID)

Returns: `cidr_block` (string), `created_at` (date-time), `description` (string), `id` (string), `status` (enum: pending, added), `updated_at` (date-time), `user_id` (string)

List connections

Returns a list of your connections irrespective of type.

`GET /connections`

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

Returns: `active` (boolean), `anchorsite_override` (enum: Latency, Chicago, IL, Ashburn, VA, San Jose, CA, Sydney, Australia, Amsterdam, Netherlands, London, UK, Toronto, Canada, Vancouver, Canada, Frankfurt, Germany), `connection_name` (string), `created_at` (string), `id` (string), `outbound_voice_profile_id` (string), `record_type` (string), `tags` (array[string]), `updated_at` (string), `webhook_api_version` (enum: 1, 2), `webhook_event_failover_url` (uri), `webhook_event_url` (uri)

Retrieve a connection

Retrieves the high-level details of an existing connection. To retrieve specific authentication information, use the endpoint for the specific connection type.

`GET /connections/{id}`

	connection, err := client.Connections.Get(context.Background(), "id")
	if err != nil {
		log.Fatal(err)
	}
	fmt.Printf("%+v\n", connection.Data)

Returns: `active` (boolean), `anchorsite_override` (enum: Latency, Chicago, IL, Ashburn, VA, San Jose, CA, Sydney, Australia, Amsterdam, Netherlands, London, UK, Toronto, Canada, Vancouver, Canada, Frankfurt, Germany), `connection_name` (string), `created_at` (string), `id` (string), `outbound_voice_profile_id` (string), `record_type` (string), `tags` (array[string]), `updated_at` (string), `webhook_api_version` (enum: 1, 2), `webhook_event_failover_url` (uri), `webhook_event_url` (uri)

List credential connections
