Telnyx Sip - 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

• **Pagination:** List methods return an auto-paginating iterator. Use `for await (const item of result) { ... }` to iterate through all pages automatically.

List all Access IP Ranges

`GET /access_ip_ranges`

// Automatically fetches more pages as needed.
for await (const accessIPRange of client.accessIPRanges.list()) {
  console.log(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)

Create new Access IP Range

`POST /access_ip_ranges` — Required: `cidr_block`

Optional: `description` (string)

const accessIPRange = await client.accessIPRanges.create({ cidr_block: '203.0.113.0/24' });

console.log(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}`

const accessIPRange = await client.accessIPRanges.delete('550e8400-e29b-41d4-a716-446655440000');

console.log(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`

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

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}`

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

console.log(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

Returns a list of your credential connections.

`GET /credential_connections`

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