Telnyx Texml - Ruby

Installation

gem install telnyx

Setup

require "telnyx"

client = Telnyx::Client.new(
  api_key: ENV["TELNYX_API_KEY"], # This is the default and can be omitted
  public_key: ENV["TELNYX_PUBLIC_KEY"], # Required for client.webhooks.unwrap (webhook verification)
)

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:

begin
  result = client.messages.send_(to: "+13125550001", from: "+13125550002", text: "Hello")
rescue Telnyx::Errors::APIConnectionError
  puts "Network error — check connectivity and retry"
  raise
rescue Telnyx::Errors::RateLimitError
  # 429: rate limited — wait, then retry the request (bounded exponential backoff)
  sleep(1) # Check Retry-After header for actual delay
  # ...retry the call here (give up after a few attempts); otherwise re-raise:
  raise
rescue Telnyx::Errors::APIStatusError => e
  puts "API error #{e.status}: #{e.message}"
  if e.status == 422
    puts "Validation error — check required fields and formats"
  end
  raise # A failed request must never look like success to the caller
end

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 `.auto_paging_each` for automatic iteration: `page.auto_paging_each { |item| puts item.id }`.

Fetch multiple call resources

Returns multiple call resources for an account. This endpoint is eventually consistent.

`GET /texml/Accounts/{account_sid}/Calls`

response = client.texml.accounts.calls.retrieve_calls("account_sid")

puts(response)

Returns: `calls` (array[object]), `end` (integer), `first_page_uri` (string), `next_page_uri` (string), `page` (integer), `page_size` (integer), `start` (integer), `uri` (string)

Initiate an outbound call

Initiate an outbound TeXML call. Telnyx will request TeXML from the XML Request URL configured for the connection in the Mission Control Portal.

`POST /texml/Accounts/{account_sid}/Calls` — Required: `Url`

Optional: `Texml` (object)

response = client.texml.accounts.calls.calls("account_sid", params: {Url: "https://www.example.com/texml.xml"})

puts(response)

Returns: `from` (string), `status` (string), `to` (string)

Fetch a call

Returns an individual call identified by its CallSid. This endpoint is eventually consistent.

`GET /texml/Accounts/{account_sid}/Calls/{call_sid}`

call = client.texml.accounts.calls.retrieve("call_sid", account_sid: "550e8400-e29b-41d4-a716-446655440000")

puts(call)

Returns: `account_sid` (string), `answered_by` (enum: human, machine, not_sure), `caller_name` (string), `date_created` (string), `date_updated` (string), `direction` (enum: inbound, outbound), `duration` (string), `end_time` (string), `from` (string), `from_formatted` (string), `price` (string), `price_unit` (string), `sid` (string), `start_time` (string), `status` (enum: ringing, in-progress, canceled, completed, failed, busy, no-answer), `to` (string), `to_formatted` (string), `uri` (string)

Update call

Update TeXML call. Please note that the keys present in the payload MUST BE formatted in CamelCase as specified in the example.

`POST /texml/Accounts/{account_sid}/Calls/{call_sid}`

call = client.texml.accounts.calls.update("call_sid", account_sid: "550e8400-e29b-41d4-a716-446655440000")

puts(call)

Returns: `account_sid` (string), `answered_by` (enum: human, machine, not_sure), `caller_name` (string), `date_created` (string), `date_updated` (string), `direction` (enum: inbound, outbound), `duration` (string), `end_time` (string), `from` (string), `from_formatted` (string), `price` (string), `price_unit` (string), `sid` (string), `start_time` (string), `status` (enum: ringing, in-progress, canceled, completed, failed, busy, no-answer), `to` (string), `to_formatted` (string), `uri` (string)

Fetch recordings for a call

Returns recordings for a call identified by call_sid.

`GET /texml/Accounts/{account_sid}/Calls/{call_sid}/Recordings.json`

response = client.texml.accounts.calls.recordings_json.retrieve_recordings_json(
  "call_sid",
  account_sid: "550e8400-e29b-41d4-a716-446655440000"
)

puts(response)

Returns: `end` (integer), `first_page_uri` (uri), `next_page_uri` (string), `page` (integer), `page_size` (integer), `previous_page_uri` (uri), `recordings` (array[object]), `start` (integer), `uri` (string)

Request recording for a call

Starts recording with specified parameters for call identified by call_sid.

`POST /texml/Accounts/{account_sid}/Calls/{call_sid}/Recordings.json`

response = client.texml.accounts.calls.recordings_json.recordings_json("call_sid", account_sid: "550e8400-e29b-41d4-a716-446655440000")

puts(response)

Returns: `account_sid` (string), `call_sid` (string), `channels` (enum: 1, 2), `conference_sid` (uuid), `date_created` (date-time), `date_updated` (date-time), `duration` (string | null), `error_code` (string | null), `price` (string | null), `price_unit` (string | null), `sid` (string), `source` (enum: StartCallRecordingAPI, StartConferenceRecordingAPI, OutboundAPI, DialVerb, Conference, RecordVerb, Trunking), `start_time` (date-time), `track` (enum: inbound, outbound, both), `uri` (string)
