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.

Core Tasks

Create a brand

Brand registration is the entrypoint for any US A2P 10DLC campaign flow.

client.messaging10dlc.brand.create() — POST /10dlc/brand

Parameter	Type	Required	Description
`entityType`	object	Yes	Entity type behind the brand.
`displayName`	string	Yes	Display name, marketing name, or DBA name of the brand.

});

console.log(telnyxBrand.identityStatus);

Primary response fields:

telnyxBrand.brandId
telnyxBrand.identityStatus

  usecase: '2FA',
    sampleMessages: ["Your verification code is {{code}}"],
});

console.log(telnyxCampaignCsp.brandId);

Primary response fields:

telnyxCampaignCsp.campaignId
telnyxCampaignCsp.brandId
telnyxCampaignCsp.campaignStatus
telnyxCampaignCsp.submissionStatus

Assign a messaging profile to a campaign

Messaging profile assignment is the practical handoff from registration to send-ready messaging infrastructure.

client.messaging10dlc.phoneNumberAssignmentByProfile.assign() — POST /10dlc/phoneNumberAssignmentByProfile

Parameter	Type	Required	Description
`messagingProfileId`	string (UUID)	Yes	The ID of the messaging profile that you want to link to the...

`tcrCampaignId`	string (UUID)	No	The TCR ID of the shared campaign you want to link to the sp...

const response = await client.messaging10dlc.phoneNumberAssignmentByProfile.assign({
  messagingProfileId: '4001767e-ce0f-4cae-9d5f-0d5e636e7809',
    campaignId: 'CXXX001',
});

console.log(response.messagingProfileId);

Primary response fields:

response.messagingProfileId
response.campaignId
response.taskId
response.tcrCampaignId

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.

Campaign Status Update

Field	Type	Description
`brandId`	string	Brand ID associated with the campaign.
`campaignId`	string	The ID of the campaign.
`createDate`	string	Unix timestamp when campaign was created.
`cspId`	string	Alphanumeric identifier of the CSP associated with this campaign.
`isTMobileRegistered`	boolean	Indicates whether the campaign is registered with T-Mobile.
`type`	enum: TELNYX_EVENT, REGISTRATION, MNO_REVIEW, TELNYX_REVIEW, NUMBER_POOL_PROVISIONED, NUMBER_POOL_DEPROVISIONED, TCR_EVENT, VERIFIED
`description`	string	Description of the event.
`status`	enum: ACCEPTED, REJECTED, DORMANT, success, failed	The status of the campaign.

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