+Using custom path for SSL certificates
+--------------------------------------
+
+If you need to use a custom path for SSL certificates, you can set the ``REQUESTS_CA_BUNDLE`` environment variable in your playbook.
+
+For example, if ``/var/vmware/certs/vcenter1.crt`` is the SSL certificate for your vCenter Server, you can use the :ref:`environment <playbooks_environment>` keyword to pass it to the modules:
+
+.. code-block:: yaml
+
+   - name: Gather all tags from vCenter
+     community.vmware.vmware_tag_info:
+       validate_certs: True
+       hostname: '{{ vcenter_hostname }}'
+       username: '{{ vcenter_username }}'
+       password: '{{ vcenter_password }}'
+     environment:
+       REQUESTS_CA_BUNDLE: /var/vmware/certs/vcenter1.crt
