WhatsApp resource methods build a double `/v2/v2/` path → 404 (v4.168.0)

[paulmartins]

Summary

Every method under the whatsapp.* resource group builds a request URL with a doubled version prefix (/v2/v2/...), causing a 404 (10005 – Resource not found). The whatsapp.* path templates include a leading /v2, but the client's base_url already ends in /v2 — so they compound. Non-WhatsApp resources are correct and unaffected.

Version

• telnyx 4.168.0 (Python)
• Default base_url: https://api.telnyx.com/v2/

Reproduction

import telnyx
client = telnyx.Telnyx(api_key="...")
client.whatsapp.business_accounts.phone_numbers.initialize_verification(
    "test_waba_id",
    phone_number="test_phone_number",
    display_name="Example",
    verification_method="sms",
)

Actual request URL:

https://api.telnyx.com/v2/v2/whatsapp/business_accounts/test_waba_id/phone_numbers

→ 404 {'errors': [{'code': '10005', 'title': 'Resource not found', ...}]}

Expected:

https://api.telnyx.com/v2/whatsapp/business_accounts/test_waba_id/phone_numbers

Root cause

The whatsapp.* path templates start with /v2, unlike every other resource, which is relative to the already-versioned base_url:

Method	Path template in SDK
phone_numbers.messaging.update	/phone_numbers/{id}/messaging ✅ (no /v2)
whatsapp.business_accounts.phone_numbers.initialize_verification	/v2/whatsapp/business_accounts/{id}/phone_numbers ❌
whatsapp.business_accounts.phone_numbers.list	/v2/whatsapp/business_accounts/{id}/phone_numbers ❌
whatsapp.phone_numbers.verify	/v2/whatsapp/phone_numbers/{phone_number}/verify ❌

(Likely all whatsapp.* methods are affected; the three above are what I use.)

Suggested fix

Strip the leading /v2 from the whatsapp.* path templates so they're relative to base_url like every other resource. This looks like an
OpenAPI-spec/codegen inconsistency where the WhatsApp paths were specified with the version segment included.

Workaround

Construct a separate client with the host root as the base URL for WhatsApp calls:

wa = telnyx.Telnyx(api_key="...", base_url="https://api.telnyx.com")
wa.whatsapp.business_accounts.phone_numbers.initialize_verification(...)  # → single /v2, works

(Can't be used for the whole client, since it would then break the correctly-pathed non-WhatsApp resources.)
