Telnyx 10DLC - 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 telnyxBrand = await client.messaging10dlc.brand.create({ country: 'US', displayName: 'ABC Mobile', email: 'support@example.com', entityType: 'PRIVATE_PROFIT', vertical: 'TECHNOLOGY', }); } catch (err) { if (err instanceof Telnyx.APIConnectionError) { console.error('Network error — check connectivity and retry'); } else if (err instanceof Telnyx.RateLimitError) { 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.

Operational Caveats

  • 10DLC is sequential: create the brand first, then submit the campaign, then attach messaging infrastructure such as the messaging profile.

  • Registration calls are not enough by themselves. Messaging cannot use the campaign until the assignment step completes successfully.

  • Treat registration status fields as part of the control flow. Do not assume the campaign is send-ready until the returned status fields confirm it.

Reference Use Rules

Do not invent Telnyx parameters, enums, response fields, or webhook fields.

  • If the parameter, enum, or response field you need is not shown inline in this skill, read references/api-details.md before writing code.

  • Before using any operation in ## Additional Operations , read the optional-parameters section and the response-schemas section.

  • Before reading or matching webhook fields beyond the inline examples, read the webhook payload reference.

Webhook Verification

Telnyx signs webhooks with Ed25519. Each request includes telnyx-signature-ed25519

and telnyx-timestamp headers. Always verify signatures in production:

// In your webhook handler (e.g., Express — use raw body, not parsed JSON): app.post('/webhooks', express.raw({ type: 'application/json' }), async (req, res) => { try { const event = await client.webhooks.unwrap(req.body.toString(), { headers: req.headers, }); // Signature valid — event is the parsed webhook payload console.log('Received event:', event.data.event_type); res.status(200).send('OK'); } catch (err) { console.error('Webhook verification failed:', err.message); res.status(400).send('Invalid signature'); } });

Webhooks

These webhook payload fields are inline because they are part of the primary integration path.

campaignId

createDate

string Unix timestamp when campaign was created.

cspId

If you need webhook fields that are not listed inline here, read the webhook payload reference before writing the handler.
