Telnyx 10DLC - Go

Installation

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

Setup

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:

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 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

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

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:
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 before writing the handler.
