Telnyx Sip - Python

Installation

pip install telnyx

Setup

import os
from telnyx import Telnyx

client = Telnyx(
    api_key=os.environ.get("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:

import telnyx

try:
    result = client.messages.send(to="+13125550001", from_="+13125550002", text="Hello")
except telnyx.APIConnectionError:
    print("Network error — check connectivity and retry")
except telnyx.RateLimitError:
    # 429: rate limited — wait and retry with exponential backoff
    import time
    time.sleep(1)  # Check Retry-After header for actual delay
except telnyx.APIStatusError as e:
    print(f"API error {e.status_code}: {e.message}")
    if e.status_code == 422:
        print("Validation error — check required fields and formats")

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:** List methods return an auto-paginating iterator. Use `for item in page_result:` to iterate through all pages automatically.

List all Access IP Ranges

`GET /access_ip_ranges`

page = client.access_ip_ranges.list()
page = page.data[0]
print(page.id)

Returns: `cidr_block` (string), `created_at` (date-time), `description` (string), `id` (string), `status` (enum: pending, added), `updated_at` (date-time), `user_id` (string)

Create new Access IP Range

`POST /access_ip_ranges` — Required: `cidr_block`

Optional: `description` (string)

access_ip_range = client.access_ip_ranges.create(
    cidr_block="203.0.113.0/24",
)
print(access_ip_range.id)

Returns: `cidr_block` (string), `created_at` (date-time), `description` (string), `id` (string), `status` (enum: pending, added), `updated_at` (date-time), `user_id` (string)

Delete access IP ranges

`DELETE /access_ip_ranges/{access_ip_range_id}`

access_ip_range = client.access_ip_ranges.delete(
    "access_ip_range_id",
)
print(access_ip_range.id)

Returns: `cidr_block` (string), `created_at` (date-time), `description` (string), `id` (string), `status` (enum: pending, added), `updated_at` (date-time), `user_id` (string)

List connections

Returns a list of your connections irrespective of type.

`GET /connections`

page = client.connections.list()
page = page.data[0]
print(page.id)

Returns: `active` (boolean), `anchorsite_override` (enum: Latency, Chicago, IL, Ashburn, VA, San Jose, CA, Sydney, Australia, Amsterdam, Netherlands, London, UK, Toronto, Canada, Vancouver, Canada, Frankfurt, Germany), `connection_name` (string), `created_at` (string), `id` (string), `outbound_voice_profile_id` (string), `record_type` (string), `tags` (array[string]), `updated_at` (string), `webhook_api_version` (enum: 1, 2), `webhook_event_failover_url` (uri), `webhook_event_url` (uri)

Retrieve a connection

Retrieves the high-level details of an existing connection. To retrieve specific authentication information, use the endpoint for the specific connection type.

`GET /connections/{id}`

connection = client.connections.retrieve(
    "id",
)
print(connection.data)

Returns: `active` (boolean), `anchorsite_override` (enum: Latency, Chicago, IL, Ashburn, VA, San Jose, CA, Sydney, Australia, Amsterdam, Netherlands, London, UK, Toronto, Canada, Vancouver, Canada, Frankfurt, Germany), `connection_name` (string), `created_at` (string), `id` (string), `outbound_voice_profile_id` (string), `record_type` (string), `tags` (array[string]), `updated_at` (string), `webhook_api_version` (enum: 1, 2), `webhook_event_failover_url` (uri), `webhook_event_url` (uri)

List credential connections

Returns a list of your credential connections.

`GET /credential_connections`

page = client.credential_connections.list()
page = page.data[0]
print(page.id)

Returns: `active` (boolean), `anchorsite_override` (enum: Latency, Chicago, IL, Ashburn, VA, San Jose, CA, Sydney, Australia, Amsterdam, Netherlands, London, UK, Toronto, Canada, Vancouver, Canada, Frankfurt, Germany), `android_push_credential_id` (string | null), `call_cost_in_webhooks` (boolean), `connection_name` (string), `created_at` (string), `default_on_hold_comfort_noise_enabled` (boolean), `dtmf_type` (enum: RFC 2833, Inband, SIP INFO), `encode_contact_header_enabled` (boolean), `encrypted_media` (enum: SRTP, None), `id` (string), `inbound` (object), `ios_push_credential_id` (string | null), `jitter_buffer` (object), `noise_suppression` (enum: inbound, outbound, both, disabled), `noise_suppression_details` (object), `onnet_t38_passthrough_enabled` (boolean), `outbound` (object), `password` (string), `record_type` (string), `rtcp_settings` (object), `sip_uri_calling_preference` (enum: disabled, unrestricted, internal), `tags` (array[string]), `updated_at` (string), `user_name` (string), `webhook_api_version` (enum: 1, 2), `webhook_event_failover_url` (uri), `webhook_event_url` (uri), `webhook_timeout_secs` (integer | null)
