Telnyx Messaging - Ruby

Installation

bash

gem install telnyx

Setup

ruby

require "telnyx"

client = Telnyx::Client.new(
  api_key: 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:

ruby

response = client.messages.send_(to: "+18445550001", from: "+18005550101", text: "Hello from Telnyx!")
puts(response)

Common error codes:

invalid API key,

insufficient permissions,

resource not found,

validation error (check field formats),

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

.auto_paging_each

for automatic iteration:

page.auto_paging_each { |item| puts item.id }

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

Parameter	Type	Required	Description
`from`	string (E.164)	Yes	A valid alphanumeric sender ID on the user's account.

Webhook Verification

Telnyx signs webhooks with Ed25519. Each request includes

telnyx-signature-ed25519

and

telnyx-timestamp

headers. Always verify signatures in production:

ruby

# In your webhook handler (e.g., Sinatra — use raw body):
post "/webhooks" do
  payload = request.body.read
  headers = {
    "telnyx-signature-ed25519" => request.env["HTTP_TELNYX_SIGNATURE_ED25519"],
    "telnyx-timestamp" => request.env["HTTP_TELNYX_TIMESTAMP"],
  }
  begin
    event = client.webhooks.unwrap(payload, headers)
  rescue => e
    halt 400, "Invalid signature: #{e.message}"
  end
  # Signature valid — event is the parsed webhook payload
  puts "Received event: #{event.data.event_type}"
  status 200
end

Webhooks

These webhook payload fields are inline because they are part of the primary integration path.
