Telnyx Numbers Python

Telnyx Numbers - 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:
    available_phone_numbers = client.available_phone_numbers.list()
except telnyx.APIConnectionError:
    print("Network error — check connectivity and retry")
except telnyx.RateLimitError:
    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

• Phone numbers must be in E.164 format (e.g., +13125550001). Include the + prefix and country code. No spaces, dashes, or parentheses.
• Pagination: List methods return an auto-paginating iterator. Use for item in page_result: to iterate through all pages automatically.

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.

Core Tasks

Search available phone numbers

Number search is the entrypoint for provisioning. Agents need the search method, key query filters, and the fields returned for candidate numbers.

client.available_phone_numbers.list() — GET /available_phone_numbers

available_phone_numbers = client.available_phone_numbers.list()
print(available_phone_numbers.data)

Response wrapper:

• items: available_phone_numbers.data
• pagination: available_phone_numbers.meta

Primary item fields:

• phone_number
• record_type
• quickship
• reservable
• best_effort
• cost_information

Create a number order

Number ordering is the production provisioning step after number selection.

client.number_orders.create() — POST /number_orders

number_order = client.number_orders.create(
    phone_numbers=[{"phone_number": "+18005550101"}],
)
print(number_order.data)

Primary response fields:

• number_order.data.id
• number_order.data.status
• number_order.data.phone_numbers_count
• number_order.data.requirements_met
• number_order.data.messaging_profile_id
• number_order.data.connection_id

Check number order status

Order status determines whether provisioning completed or additional requirements are still blocking fulfillment.

client.number_orders.retrieve() — GET /number_orders/{number_order_id}

number_order = client.number_orders.retrieve(
    "number_order_id",
)
print(number_order.data)

Primary response fields:

• number_order.data.id
• number_order.data.status
• number_order.data.requirements_met
• number_order.data.phone_numbers_count
• number_order.data.phone_numbers
• number_order.data.connection_id

Important Supporting Operations

Use these when the core tasks above are close to your flow, but you need a common variation or follow-up step.

Create a number reservation

Create or provision an additional resource when the core tasks do not cover this flow.

client.number_reservations.create() — POST /number_reservations

number_reservation = client.number_reservations.create(

)
print(number_reservation.data)

Primary response fields:

• number_reservation.data.id

Retrieve a number reservation

Fetch the current state before updating, deleting, or making control-flow decisions.
