Telnyx Messaging - 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"

response, err := client.Messages.Send(context.Background(), telnyx.MessageSendParams{
		To: "+18445550001",
		From: "+18005550101",
		Text: "Hello from Telnyx!",
	})
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() }.

Operational Caveats

The sending number must already be assigned to the correct messaging profile before you send traffic from it.
US A2P long-code traffic must complete 10DLC registration before production sending or carriers will block or heavily filter messages.
Delivery webhooks are asynchronous. Treat the send response as acceptance of the request, not final carrier delivery.

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

Send an SMS

Primary outbound messaging flow. Agents need exact request fields and delivery-related response fields.

client.Messages.Send() — POST /messages

Parameter	Type	Required	Description
`To`	string (E.164)	Yes	Receiving address (+E.164 formatted phone number or short co...
`From`	string (E.164)	Yes	Sending address (+E.164 formatted phone number, alphanumeric...
`Text`	string	Yes	Message body (i.e., content) as a non-empty string.

...			+7 optional params in references/api-details.md

	response, err := client.Messages.Send(context.Background(), telnyx.MessageSendParams{
		To: "+18445550001",
		From: "+18005550101",
		Text: "Hello from Telnyx!",
	})
	if err != nil {

Primary response fields:

response.Data.ID
response.Data.To
response.Data.From
response.Data.Text
response.Data.SentAt
response.Data.Errors

Send an SMS with an alphanumeric sender ID

Common sender variant that requires different request shape.

client.Messages.SendWithAlphanumericSender() — POST /messages/alphanumeric_sender_id

Parameter	Type	Required	Description
`From`	string (E.164)	Yes	A valid alphanumeric sender ID on the user's account.
`To`	string (E.164)	Yes	Receiving address (+E.164 formatted phone number or short co...
`Text`	string	Yes	The message body.
`MessagingProfileId`	string (UUID)	Yes	The messaging profile ID to use.
`WebhookUrl`	string (URL)	No	Callback URL for delivery status updates.

		From:               "MyCompany",
		MessagingProfileID: "182bd5e5-6e1a-4fe4-a799-aa6d9a6ab26e",
		Text: "Hello from Telnyx!",
		To: "+13125550001",
	})
	if err != nil {
		log.Fatal(err)
	}
	fmt.Printf("%+v\n", response.Data)

Primary response fields:

response.Data.ID
response.Data.To
response.Data.From
response.Data.Text
response.Data.SentAt
response.Data.Errors

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.

Delivery Update

`data.event_type`	enum: message.sent, message.finalized	The type of event being delivered.
`data.payload.id`	uuid	Identifies the type of resource.

`data.payload.completed_at`	date-time	ISO 8601 formatted date indicating when the message was finalized.
`data.payload.cost`	object \| null
`data.payload.errors`	array[object]	These errors may point at addressees when referring to unsuccessful/unconfirm...

Inbound Message

Field	Type	Description
`data.event_type`	enum: message.received	The type of event being delivered.
`data.payload.id`	uuid	Identifies the type of resource.
`data.payload.direction`	enum: inbound	The direction of the message.
`data.payload.to`	array[object]
`data.payload.text`	string	Message body (i.e., content) as a non-empty string.
`data.payload.type`	enum: SMS, MMS	The type of message.
`data.payload.media`	array[object]
`data.record_type`	enum: event	Identifies the type of the resource.

If you need webhook fields that are not listed inline here, read the webhook payload reference before writing the handler.

# Telnyx Messaging - 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

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.
