+## Configuring destination credentials in code
+
+If you need to manage destination credentials programmatically, such as retrieving them from environment variables, you can define them directly in your pipeline code.
+
+The following example demonstrates how to use [GcpServiceAccountCredentials](complex_types#gcp-credentials) to set up a pipeline with a BigQuery destination.
+
+```py
+import os
+
+import dlt
+from dlt.sources.credentials import GcpServiceAccountCredentials
+from dlt.destinations import bigquery
+
+# Retrieve credentials from the environment variable
+creds_dict = os.getenv('BIGQUERY_CREDENTIALS')
+
+# Create credentials instance and parse them from a native representation
+gcp_credentials = GcpServiceAccountCredentials()
+gcp_credentials.parse_native_representation(creds_dict)
+
+# Pass the credentials to the BigQuery destination
+pipeline = dlt.pipeline(destination=bigquery(credentials=gcp_credentials))
+pipeline.run([{"key1": "value1"}], table_name="temp")
+```
