+
+Adds support for Client Side Certificates to the ``webservice`` module.

+
+Configuration
+=============
+
+Certificate paths are configured via ``server_environment``. Add the
+configuration section matching your backend's ``tech_name`` to your
+server environment files:
+
+::
+
+   [webservice_backend.my_secure_service]
+   auth_type = client_certificate
+   client_certificate_path = /etc/odoo/certs/client.crt
+   # Optional: Leave empty if the private key is bundled in the certificate file
+   client_private_key_path = /etc/odoo/certs/client.key
+
+Usage
+=====
+
+When a call is made using the backend, the adapter automatically injects
+the ``cert`` parameter into the underlying Python ``requests`` call
+based on the provided configuration:
+
+-  **Certificate only:** Passed as ``cert='/path/to/file'`` (a single
+   file containing the private key and the certificate).
+-  **Certificate and Key:** Passed as a tuple
+   ``cert=('/path/to/crt', '/path/to/key')``.
+
+Warning: the private key to your local certificate must be unencrypted.
+Currently, ``requests`` does not support using encrypted keys.
+
+See `Requests: Client Side
+Certificates <https://requests.readthedocs.io/en/latest/user/advanced/#client-side-certificates>`__
+for underlying implementation details.
+
