# Telnyx Numbers - JavaScript

## Installation

```bash
npm install telnyx@6.74.2
```

## 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 availablePhoneNumbers = await client.availablePhoneNumbers.list();
} 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

- **Phone numbers** must be in E.164 format (e.g., `+13125550001`). Include the `+` prefix and country code. No spaces, dashes, or parentheses.
- **Pagination:** List methods return an auto-paginating iterator. Use `for await (const item of result) { ... }` to iterate through all pages automatically.

## 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).

## Core Tasks

### Search available phone numbers

Number search is the entrypoint for provisioning. Agents need the search method, key query filters, and the fields returned for candidate numbers.

`client.availablePhoneNumbers.list()` — `GET /available_phone_numbers`

| Parameter | Type | Required | Description |
|-----------|------|----------|-------------|
| `filter` | object | No | Consolidated filter parameter (deepObject style). |

```javascript
const availablePhoneNumbers = await client.availablePhoneNumbers.list();

console.log(availablePhoneNumbers.data);
```

Response wrapper:
- items: `availablePhoneNumbers.data`
- pagination: `availablePhoneNumbers.meta`

Primary item fields:
- `phoneNumber`
- `recordType`
- `quickship`
- `reservable`
- `bestEffort`
- `costInformation`

### Create a number order

Number ordering is the production provisioning step after number selection.

`client.numberOrders.create()` — `POST /number_orders`

| Parameter | Type | Required | Description |
|-----------|------|----------|-------------|
| `phone_numbers` | array[object] | Yes |  |
| `connection_id` | string (UUID) | No | Identifies the connection associated with this phone number. |
| `messaging_profile_id` | string (UUID) | No | Identifies the messaging profile associated with the phone n... |
| `billing_group_id` | string (UUID) | No | Identifies the billing group associated with the phone numbe... |
| ... | | | +1 optional params in [references/api-details.md](references/api-details.md) |

```javascript
const numberOrder = await client.numberOrders.create({
    phone_numbers: [{"phone_number": "+18005550101"}],
});

console.log(numberOrder.data);
```

Primary response fields:
- `numberOrder.data.id`
- `numberOrder.data.status`
- `numberOrder.data.phoneNumbersCount`
- `numberOrder.data.requirementsMet`
- `numberOrder.data.messagingProfileId`
- `numberOrder.data.connectionId`

### Check number order status

Order status determines whether provisioning completed or additional requirements are still blocking fulfillment.

`client.numberOrders.retrieve()` — `GET /number_orders/{number_order_id}`

| Parameter | Type | Required | Description |
|-----------|------|----------|-------------|
| `number_order_id` | string (UUID) | Yes | The number order ID. |

```javascript
const numberOrder = await client.numberOrders.retrieve('550e8400-e29b-41d4-a716-446655440000');

console.log(numberOrder.data);
```

Primary response fields:
- `numberOrder.data.id`
- `numberOrder.data.status`
- `numberOrder.data.requirementsMet`
- `numberOrder.data.phoneNumbersCount`
