# Telnyx 10DLC - JavaScript

## Installation

```bash
npm install telnyx
```

## Setup

```javascript
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:

```javascript
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](references/api-details.md) before writing code.
- Before using any operation in `## Additional Operations`, read [the optional-parameters section](references/api-details.md#optional-parameters) and [the response-schemas section](references/api-details.md#response-schemas).
- Before reading or matching webhook fields beyond the inline examples, read [the webhook payload reference](references/api-details.md#webhook-payload-fields).

| `brandId` | string (UUID) | Yes | Alphanumeric identifier of the brand associated with this ca... |
