Build voice applications using TeXML markup language (TwiML-compatible). Manage applications, calls, conferences, recordings, queues, and streams. This skill provides JavaScript SDK examples.
npm install telnyx
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.
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).
for await (const item of result) { ... } to iterate through all pages automatically.Returns multiple call resources for an account. This endpoint is eventually consistent.
