Telnyx Verify - 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

• **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.

Lookup phone number data

Returns information about the provided phone number.

`GET /number_lookup/{phone_number}`

number_lookup = client.number_lookup.retrieve(
    phone_number="+18665552368",
)
print(number_lookup.data)

Returns: `caller_name` (object), `carrier` (object), `country_code` (string), `fraud` (string | null), `national_format` (string), `phone_number` (string), `portability` (object), `record_type` (string)

List verifications by phone number

`GET /verifications/by_phone_number/{phone_number}`

by_phone_numbers = client.verifications.by_phone_number.list(
    "+13035551234",
)
print(by_phone_numbers.data)

Returns: `created_at` (string), `custom_code` (string | null), `id` (uuid), `phone_number` (string), `record_type` (enum: verification), `status` (enum: pending, accepted, invalid, expired, error), `timeout_secs` (integer), `type` (enum: sms, call, flashcall, whatsapp), `updated_at` (string), `verify_profile_id` (uuid)

Verify verification code by phone number

`POST /verifications/by_phone_number/{phone_number}/actions/verify` — Required: `code`, `verify_profile_id`

    code="17686",
    verify_profile_id="12ade33a-21c0-473b-b055-b3c836e1c292",
)
print(verify_verification_code_response.data)

Returns: `phone_number` (string), `response_code` (enum: accepted, rejected)

Trigger Call verification

`POST /verifications/call` — Required: `phone_number`, `verify_profile_id`

Optional: `custom_code` (string | null), `extension` (string | null), `timeout_secs` (integer)

create_verification_response = client.verifications.trigger_call(
    phone_number="+13035551234",
    verify_profile_id="12ade33a-21c0-473b-b055-b3c836e1c292",
)
print(create_verification_response.data)

    phone_number="+13035551234",
    verify_profile_id="12ade33a-21c0-473b-b055-b3c836e1c292",
)
print(create_verification_response.data)

Returns: `created_at` (string), `custom_code` (string | null), `id` (uuid), `phone_number` (string), `record_type` (enum: verification), `status` (enum: pending, accepted, invalid, expired, error), `timeout_secs` (integer), `type` (enum: sms, call, flashcall, whatsapp), `updated_at` (string), `verify_profile_id` (uuid)
