Telnyx Numbers Services - 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
    public_key=os.environ.get("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:

import telnyx

try:
    result = client.messages.send(to="+13125550001", from_="+13125550002", text="Hello")
except telnyx.APIConnectionError:
    print("Network error — check connectivity and retry")
    raise
except telnyx.RateLimitError:
    # 429: rate limited — wait, then retry the request (bounded exponential backoff)
    import time
    time.sleep(1)  # Check Retry-After header for actual delay
    # ...retry the call here (give up after a few attempts); otherwise re-raise:
    raise
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")
    raise  # A failed request must never look like success to the caller

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 your voice channels for non-US zones

Returns the non-US voice channels for your account. voice channels allow you to use Channel Billing for calls to your Telnyx phone numbers. Please check the Telnyx Support Articles section for full information and examples of how to utilize Channel Billing.

`GET /channel_zones`

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

Returns: `channels` (int64), `countries` (array[string]), `created_at` (string), `id` (string), `name` (string), `record_type` (enum: channel_zone), `updated_at` (string)

Update voice channels for non-US Zones

Update the number of Voice Channels for the Non-US Zones. This allows your account to handle multiple simultaneous inbound calls to Non-US numbers. Use this endpoint to increase or decrease your capacity based on expected call volume.

`PUT /channel_zones/{channel_zone_id}` — Required: `channels`

channel_zone = client.channel_zones.update(
    channel_zone_id="550e8400-e29b-41d4-a716-446655440000",
    channels=0,
)
print(channel_zone.id)

Returns: `channels` (int64), `countries` (array[string]), `created_at` (string), `id` (string), `name` (string), `record_type` (enum: channel_zone), `updated_at` (string)

List dynamic emergency addresses

Returns the dynamic emergency addresses according to filters

`GET /dynamic_emergency_addresses`

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

Returns: `administrative_area` (string), `country_code` (enum: US, CA, PR), `created_at` (string), `extended_address` (string), `house_number` (string), `house_suffix` (string), `id` (string), `locality` (string), `postal_code` (string), `record_type` (string), `sip_geolocation_id` (string), `status` (enum: pending, activated, rejected), `street_name` (string), `street_post_directional` (string), `street_pre_directional` (string), `street_suffix` (string), `updated_at` (string)

Create a dynamic emergency address.

Creates a dynamic emergency address, the validated physical location used when provisioning dynamic emergency endpoints.

`POST /dynamic_emergency_addresses` — Required: `house_number`, `street_name`, `locality`, `administrative_area`, `postal_code`, `country_code`

Optional: `created_at` (string), `extended_address` (string), `house_suffix` (string), `id` (string), `record_type` (string), `sip_geolocation_id` (string), `status` (enum: pending, activated, rejected), `street_post_directional` (string), `street_pre_directional` (string), `street_suffix` (string), `updated_at` (string)

dynamic_emergency_address = client.dynamic_emergency_addresses.create(
    administrative_area="TX",
    country_code="US",
    house_number="600",
    locality="Austin",
    postal_code="78701",
    street_name="Congress",
)
print(dynamic_emergency_address.data)

Returns: `administrative_area` (string), `country_code` (enum: US, CA, PR), `created_at` (string), `extended_address` (string), `house_number` (string), `house_suffix` (string), `id` (string), `locality` (string), `postal_code` (string), `record_type` (string), `sip_geolocation_id` (string), `status` (enum: pending, activated, rejected), `street_name` (string), `street_post_directional` (string), `street_pre_directional` (string), `street_suffix` (string), `updated_at` (string)

Get a dynamic emergency address

Returns the dynamic emergency address based on the ID provided

`GET /dynamic_emergency_addresses/{id}`

dynamic_emergency_address = client.dynamic_emergency_addresses.retrieve(
    "182bd5e5-6e1a-4fe4-a799-aa6d9a6ab26e",
)
print(dynamic_emergency_address.data)
