# Telnyx Numbers - Go

## Installation

```bash
go get github.com/team-telnyx/telnyx-go
```

## Setup

```go
import (
  "context"
  "fmt"
  "os"

  "github.com/team-telnyx/telnyx-go"
  "github.com/team-telnyx/telnyx-go/option"
)

client := telnyx.NewClient(
  option.WithAPIKey(os.Getenv("TELNYX_API_KEY")),
)
```

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:

```go
import "errors"

availablePhoneNumbers, err := client.AvailablePhoneNumbers.List(context.Background(), telnyx.AvailablePhoneNumberListParams{})
if err != nil {
  var apiErr *telnyx.Error
  if errors.As(err, &apiErr) {
    switch apiErr.StatusCode {
    case 422:
      fmt.Println("Validation error — check required fields and formats")
    case 429:
      fmt.Println("Rate limited, retrying...")
    default:
      fmt.Printf("API error %d: %s\n", apiErr.StatusCode, apiErr.Error())
    }
  } else {
    fmt.Println("Network error — check connectivity and retry")
  }
}
```

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:** Use `ListAutoPaging()` for automatic iteration: `iter := client.Resource.ListAutoPaging(ctx, params); for iter.Next() { item := iter.Current() }`.

## 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). |

```go
	availablePhoneNumbers, err := client.AvailablePhoneNumbers.List(context.Background(), telnyx.AvailablePhoneNumberListParams{})
	if err != nil {
		log.Fatal(err)
	}
	fmt.Printf("%+v\n", 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.New()` — `POST /number_orders`

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

```go
	numberOrder, err := client.NumberOrders.New(context.Background(), telnyx.NumberOrderNewParams{
		PhoneNumbers: []telnyx.NumberOrderNewParamsPhoneNumber{{PhoneNumber: "+18005550101"}},
	})
	if err != nil {
		log.Fatal(err)
	}
	fmt.Printf("%+v\n", 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.Get()` — `GET /number_orders/{number_order_id}`

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

```go
	numberOrder, err := client.NumberOrders.Get(context.Background(), "number_order_id")
	if err != nil {
		log.Fatal(err)
	}
	fmt.Printf("%+v\n", numberOrder.Data)
```

Primary response fields:
- `numberOrder.Data.ID`
- `numberOrder.Data.Status`
- `numberOrder.Data.RequirementsMet`
- `numberOrder.Data.PhoneNumbersCount`
- `numberOrder.Data.PhoneNumbers`
- `numberOrder.Data.ConnectionID`
