Research direction

Start with hubspot/crm/companies/api_client.py and search the generated API clients for uses of HTTPResponse.getheader() and getheaders(). Check how the response headers are accessed, then verify that all such clients work with urllib3 2.6.0 without the removed methods.

Written by the indexing model from the issue text.

Description

As of urllib3 2.6.0, the deprecated HTTPResponse.getheaders() and HTTPResponse.getheader() methods have been removed and replaced by the headers attribute. ( https://github.com/urllib3/urllib3/blob/main/CHANGES.rst#260-2025-12-05 )

Both of the removed methods are used in the auto generated api client, for example: https://github.com/HubSpot/hubspot-api-python/blob/master/hubspot/crm/companies/api_client.py

The code needs to be updated to be compatible with the latest version of urllib3 in order to benefit from the bug and security fixes. Any chance this could be patched?
