# Telnyx 10DLC - 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"

telnyxBrand, err := client.Messaging10dlc.Brand.New(context.Background(), telnyx.Messaging10dlcBrandNewParams{
		Country:     "US",
		DisplayName: "ABC Mobile",
		Email: "support@example.com",
		EntityType:  telnyx.EntityTypePrivateProfit,
		Vertical:    telnyx.VerticalTechnology,
	})
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

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

## 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).

## Core Tasks

### Create a brand

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

`client.Messaging10dlc.Brand.New()` — `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. |
| `Country` | string | Yes | ISO2 2 characters country code. |
| `Email` | string | Yes | Valid email address of brand support contact. |
| `Vertical` | object | Yes | Vertical or industry segment of the brand. |
| `CompanyName` | string | No | (Required for Non-profit/private/public) Legal company name. |
| `FirstName` | string | No | First name of business contact. |
| `LastName` | string | No | Last name of business contact. |
| ... | | | +16 optional params in [references/api-details.md](references/api-details.md) |

```go
	telnyxBrand, err := client.Messaging10dlc.Brand.New(context.Background(), telnyx.Messaging10dlcBrandNewParams{
		Country:     "US",
		DisplayName: "ABC Mobile",
		Email: "support@example.com",
		EntityType:  telnyx.EntityTypePrivateProfit,
		Vertical:    telnyx.VerticalTechnology,
	})
	if err != nil {
		log.Fatal(err)
	}
	fmt.Printf("%+v\n", telnyxBrand.IdentityStatus)
```

Primary response fields:
- `telnyxBrand.BrandID`
- `telnyxBrand.IdentityStatus`
- `telnyxBrand.Status`
- `telnyxBrand.DisplayName`
- `telnyxBrand.State`
- `telnyxBrand.AltBusinessID`

### Submit a campaign

Campaign submission is the compliance-critical step that determines whether traffic can be provisioned.

`client.Messaging10dlc.CampaignBuilder.Submit()` — `POST /10dlc/campaignBuilder`

| Parameter | Type | Required | Description |
|-----------|------|----------|-------------|
| `BrandId` | string (UUID) | Yes | Alphanumeric identifier of the brand associated with this ca... |
| `Description` | string | Yes | Summary description of this campaign. |
| `Usecase` | string | Yes | Campaign usecase. |
| `AgeGated` | boolean | No | Age gated message content in campaign. |
| `AutoRenewal` | boolean | No | Campaign subscription auto-renewal option. |
| `DirectLending` | boolean | No | Direct lending or loan arrangement |
| ... | | | +29 optional params in [references/api-details.md](references/api-details.md) |

```go
	telnyxCampaignCsp, err := client.Messaging10dlc.CampaignBuilder.Submit(context.Background(), telnyx.Messaging10dlcCampaignBuilderSubmitParams{
		BrandID: "BXXXXXX",
		Description: "Two-factor authentication messages",
		Usecase: "2FA",
		SampleMessages: []string{"Your verification code is {{code}}"},
	})
	if err != nil {
		log.Fatal(err)
	}
	fmt.Printf("%+v\n", telnyxCampaignCsp.BrandID)
```

Primary response fields:
- `telnyxCampaignCsp.CampaignID`
- `telnyxCampaignCsp.BrandID`
- `telnyxCampaignCsp.CampaignStatus`
- `telnyxCampaignCsp.SubmissionStatus`
- `telnyxCampaignCsp.FailureReasons`
- `telnyxCampaignCsp.Status`

### 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... |
| `CampaignId` | string (UUID) | Yes | The ID of the campaign you want to link to the specified mes... |
| `TcrCampaignId` | string (UUID) | No | The TCR ID of the shared campaign you want to link to the sp... |

```go
	response, err := client.Messaging10dlc.PhoneNumberAssignmentByProfile.Assign(context.Background(), telnyx.Messaging10dlcPhoneNumberAssignmentByProfileAssignParams{
		MessagingProfileID: "4001767e-ce0f-4cae-9d5f-0d5e636e7809",
		CampaignID: telnyx.String("CXXX001"),
	})
	if err != nil {
		log.Fatal(err)
	}
	fmt.Printf("%+v\n", 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:

```go
// In your webhook handler:
func handleWebhook(w http.ResponseWriter, r *http.Request) {
  body, _ := io.ReadAll(r.Body)
  event, err := client.Webhooks.Unwrap(body, r.Header)
  if err != nil {
    http.Error(w, "Invalid signature", http.StatusBadRequest)
    return
  }
  // Signature valid — event is the parsed webhook payload
  fmt.Println("Received event:", event.Data.EventType)
  w.WriteHeader(http.StatusOK)
}
```

## 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](references/api-details.md#webhook-payload-fields) before writing the handler.
