Telnyx Numbers Config - JavaScript

Installation

npm install telnyx@6.74.2

Setup

import Telnyx from 'telnyx';

const client = new Telnyx({
  apiKey: process.env['TELNYX_API_KEY'], // This is the default and can be omitted
});

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:

try {
  const result = await client.messages.send({ to: '+13125550001', from: '+13125550002', text: 'Hello' });
} catch (err) {
  if (err instanceof Telnyx.APIConnectionError) {
    console.error('Network error — check connectivity and retry');
  } else if (err instanceof Telnyx.RateLimitError) {
    // 429: rate limited — wait and retry with exponential backoff
    const retryAfter = err.headers?.['retry-after'] || 1;
    await new Promise(r => setTimeout(r, retryAfter * 1000));
  } else if (err instanceof Telnyx.APIError) {
    console.error(`API error ${err.status}: ${err.message}`);
    if (err.status === 422) {
      console.error('Validation error — check required fields and formats');
    }
  }
}

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

• **Phone numbers** must be in E.164 format (e.g., `+13125550001`). Include the `+` prefix and country code. No spaces, dashes, or parentheses.
• **Pagination:** List methods return an auto-paginating iterator. Use `for await (const item of result) { ... }` to iterate through all pages automatically.

Bulk update phone number profiles

`POST /messaging_numbers_bulk_updates` — Required: `messaging_profile_id`, `numbers`

Optional: `assign_only` (boolean)

const messagingNumbersBulkUpdate = await client.messagingNumbersBulkUpdates.create({
  messaging_profile_id: '00000000-0000-0000-0000-000000000000',
  numbers: ['+18880000000', '+18880000001', '+18880000002'],
});

console.log(messagingNumbersBulkUpdate.data);

Returns: `failed` (array[string]), `order_id` (uuid), `pending` (array[string]), `record_type` (enum: messaging_numbers_bulk_update), `success` (array[string])

Retrieve bulk update status

`GET /messaging_numbers_bulk_updates/{order_id}`

const messagingNumbersBulkUpdate = await client.messagingNumbersBulkUpdates.retrieve('order_id');

console.log(messagingNumbersBulkUpdate.data);

Returns: `failed` (array[string]), `order_id` (uuid), `pending` (array[string]), `record_type` (enum: messaging_numbers_bulk_update), `success` (array[string])

List mobile phone numbers with messaging settings

`GET /mobile_phone_numbers/messaging`

// Automatically fetches more pages as needed.
for await (const messagingListResponse of client.mobilePhoneNumbers.messaging.list()) {
  console.log(messagingListResponse.id);
}

Returns: `country_code` (string), `created_at` (date-time), `features` (object), `id` (string), `messaging_product` (string), `messaging_profile_id` (string | null), `organization_id` (string), `phone_number` (string), `record_type` (enum: messaging_phone_number, messaging_settings), `tags` (array[string]), `traffic_type` (string), `type` (enum: longcode), `updated_at` (date-time)

Retrieve a mobile phone number with messaging settings

`GET /mobile_phone_numbers/{id}/messaging`

const messaging = await client.mobilePhoneNumbers.messaging.retrieve('550e8400-e29b-41d4-a716-446655440000');

console.log(messaging.data);

Returns: `country_code` (string), `created_at` (date-time), `features` (object), `id` (string), `messaging_product` (string), `messaging_profile_id` (string | null), `organization_id` (string), `phone_number` (string), `record_type` (enum: messaging_phone_number, messaging_settings), `tags` (array[string]), `traffic_type` (string), `type` (enum: longcode), `updated_at` (date-time)

List phone numbers

`GET /phone_numbers`

// Automatically fetches more pages as needed.
for await (const phoneNumberDetailed of client.phoneNumbers.list()) {
  console.log(phoneNumberDetailed.id);
}

Returns: `activated_at` (object), `billing_group_id` (string | null), `call_forwarding_enabled` (boolean), `call_recording_enabled` (boolean), `caller_id_name_enabled` (boolean), `cnam_listing_enabled` (boolean), `connection_id` (string | null), `connection_name` (string | null), `country_iso_alpha2` (string), `created_at` (date-time), `customer_reference` (string | null), `deletion_lock_enabled` (boolean), `emergency_address_id` (string | null), `emergency_enabled` (boolean), `emergency_status` (enum: active, deprovisioning, disabled, provisioning, provisioning-failed), `external_pin` (string | null), `hd_voice_enabled` (boolean), `id` (string), `inbound_call_screening` (enum: disabled, reject_calls, flag_calls), `messaging_profile_id` (string | null), `messaging_profile_name` (string | null), `phone_number` (string), `phone_number_type` (enum: local, toll_free, mobile, national, shared_cost, landline, tollfree, shortcode, longcode), `purchased_at` (string), `record_type` (string), `source_type` (object), `status` (enum: purchase-pending, purchase-failed, port-pending, port-failed, active, deleted, emergency-only, ported-out, port-out-pending, requirement-info-pending, requirement-info-under-review, requirement-info-exception, provi
