Initialize the client and make a request

Quickstart from the current SDK source, using TELNYX_API_KEY for authentication:

Usage

This library uses named parameters to specify optional arguments. Parameters with a default value must be set by name.

<?php

use Telnyx\Client;

$client = new Client(apiKey: getenv('TELNYX_API_KEY') ?: 'My API Key');

$response = $client->calls->dial(
  connectionID: 'conn12345',
  from: '+15557654321',
  to: '+15551234567',
  webhookURL: 'https://your-webhook.url/events',
);

var_dump($response->data);

Source and releases

SDK releases can follow REST API changes at different times. Check the package registry for the current version and use the resource map to confirm method availability.
