+### Data Anonymization Integration Tests
+
+For Data Anonymization integration tests, configure the following variables in `.env_integration_tests`:
+
+```bash
+# Data Anonymization Configuration
+CLOUD_SDK_CFG_DATA_ANONYMIZATION_DEFAULT_URL=https://your-data-anonymization-api-url-here
+CLOUD_SDK_CFG_DATA_ANONYMIZATION_DEFAULT_CERT=your-base64-encoded-client-certificate-pem
+CLOUD_SDK_CFG_DATA_ANONYMIZATION_DEFAULT_KEY=your-base64-encoded-client-private-key-pem
+```
+
+`CLOUD_SDK_CFG_DATA_ANONYMIZATION_DEFAULT_CERT` and `CLOUD_SDK_CFG_DATA_ANONYMIZATION_DEFAULT_KEY` must contain the base64-encoded PEM content, not filesystem paths.
+
+If the certificate is managed through BTP Destination service, you can use a destination instead of inline certificate values:
+
+```bash
+CLOUD_SDK_CFG_DATA_ANONYMIZATION_DEFAULT_URL=https://your-data-anonymization-api-url-here
+CLOUD_SDK_CFG_DATA_ANONYMIZATION_DEFAULT_DESTINATION_NAME=your-client-certificate-destination-name
+```
+
+The destination must be configured with `ClientCertificateAuthentication` and reference a certificate bundle containing the client certificate and private key.
+

+"""SAP Cloud SDK extension – Data Anonymization module.
+
+Telemetry for this module is limited to operation-level metrics. Sensitive
+payloads such as source text, pseudonymization metadata, file contents, or
+certificate material are never emitted as telemetry attributes.

+Usage::

+    client = create_client()

+    assert result.result is not None
+
+    # Pseudonymize (reversible)
