Telnyx Storage - JavaScript
Installation
npm install telnyx
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).
Get Bucket SSL Certificate
Returns the stored certificate detail of a bucket, if applicable.
GET /storage/buckets/{bucketName}/ssl_certificate
const sslCertificate = await client.storage.buckets.sslCertificate.retrieve('');
console.log(sslCertificate.data);
Returns: created_at (date-time), id (string), issued_by (object), issued_to (object), valid_from (date-time), valid_to (date-time)
Add SSL Certificate
Uploads an SSL certificate and its matching secret so that you can use Telnyx's storage as your CDN.
PUT /storage/buckets/{bucketName}/ssl_certificate
const sslCertificate = await client.storage.buckets.sslCertificate.create('');
console.log(sslCertificate.data);
Returns: created_at (date-time), id (string), issued_by (object), issued_to (object), valid_from (date-time), valid_to (date-time)
Remove SSL Certificate
Deletes an SSL certificate and its matching secret.
DELETE /storage/buckets/{bucketName}/ssl_certificate
const sslCertificate = await client.storage.buckets.sslCertificate.delete('');
console.log(sslCertificate.data);
Returns: created_at (date-time), id (string), issued_by (object), issued_to (object), valid_from (date-time), valid_to (date-time)
Get API Usage
Returns the detail on API usage on a bucket of a particular time period, group by method category.
GET /storage/buckets/{bucketName}/usage/api
const response = await client.storage.buckets.usage.getAPIUsage('', { filter: { end_time: '2019-12-27T18:11:19.117Z', start_time: '2019-12-27T18:11:19.117Z' }, });
console.log(response.data);
Returns: categories (array[object]), timestamp (date-time), total (object)
Get Bucket Usage
Returns the amount of storage space and number of files a bucket takes up.
GET /storage/buckets/{bucketName}/usage/storage
const response = await client.storage.buckets.usage.getBucketUsage('');
console.log(response.data);
Returns: num_objects (integer), size (integer), size_kb (integer), timestamp (date-time)
Create Presigned Object URL
Returns a timed and authenticated URL to download (GET) or upload (PUT) an object. This is the equivalent to AWS S3’s “presigned” URL. Please note that Telnyx performs authentication differently from AWS S3 and you MUST NOT use the presign method of AWS s3api CLI or SDK to generate the presigned URL.
POST /storage/buckets/{bucketName}/{objectName}/presigned_url
Optional: ttl (integer)
const response = await client.storage.buckets.createPresignedURL('', { bucketName: '' });
console.log(response.content);
Returns: content (object)
