Telnyx Oauth - 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 }`.

Authorization server metadata

OAuth 2.0 Authorization Server Metadata (RFC 8414)

`GET /.well-known/oauth-authorization-server`

response = client.well_known.retrieve_authorization_server_metadata

puts(response)

Returns: `authorization_endpoint` (uri), `code_challenge_methods_supported` (array[string]), `grant_types_supported` (array[string]), `introspection_endpoint` (uri), `issuer` (uri), `jwks_uri` (uri), `registration_endpoint` (uri), `response_types_supported` (array[string]), `scopes_supported` (array[string]), `token_endpoint` (uri), `token_endpoint_auth_methods_supported` (array[string])

Protected resource metadata

OAuth 2.0 Protected Resource Metadata for resource discovery

`GET /.well-known/oauth-protected-resource`

response = client.well_known.retrieve_protected_resource_metadata

puts(response)

Returns: `authorization_servers` (array[string]), `resource` (uri)

OAuth authorization endpoint

OAuth 2.0 authorization endpoint for the authorization code flow

`GET /oauth/authorize`

result = client.oauth.retrieve_authorize(
  client_id: "550e8400-e29b-41d4-a716-446655440000",
  redirect_uri: "https://example.com",
  response_type: :code
)

puts(result)

Get OAuth consent token

Retrieve details about an OAuth consent token

`GET /oauth/consent/{consent_token}`

oauth = client.oauth.retrieve("consent_token")

puts(oauth)

Returns: `client_id` (string), `logo_uri` (uri), `name` (string), `policy_uri` (uri), `redirect_uri` (uri), `requested_scopes` (array[object]), `tos_uri` (uri), `verified` (boolean)

Create OAuth grant

Creates an OAuth authorization grant and returns the grant response for completing the authorization flow.

`POST /oauth/grants` — Required: `allowed`, `consent_token`

response = client.oauth.grants(allowed: true, consent_token: "eyJ0eXAiOiJKV1QiLCJhbGciOiJIUzI1NiJ9.example")

puts(response)

Returns: `redirect_uri` (uri)

Token introspection

Introspect an OAuth access token to check its validity and metadata

`POST /oauth/introspect` — Required: `token`

response = client.oauth.introspect(token: "eyJ0eXAiOiJKV1QiLCJhbGciOiJIUzI1NiJ9.example")

puts(response)

Returns: `active` (boolean), `aud` (string), `client_id` (string), `exp` (integer), `iat` (integer), `iss` (string), `scope` (string)

JSON Web Key Set

Retrieve the JSON Web Key Set for token verification

`GET /oauth/jwks`

response = client.oauth.retrieve_jwks

puts(response)

Returns: `keys` (array[object])

Dynamic client registration

Register a new OAuth client dynamically (RFC 7591)

`POST /oauth/register`

Optional: `client_name` (string), `grant_types` (array[string]), `logo_uri` (uri), `policy_uri` (uri), `redirect_uris` (array[string]), `response_types` (array[string]), `scope` (string), `token_endpoint_auth_method` (enum: none, client_secret_basic, client_secret_post), `tos_uri` (uri)

response = client.oauth.register

puts(response)
