+## Ignoring Settings
+
+Some entities in Umbraco Commerce accept configuration settings such as Payment Methods, Shipping Methods, and Tax Calculation Methods. These settings can be environment-specific, and therefore, you may not want to deploy them between environments. To prevent this from happening, you can add the following configuration options to your `appsettings.json` file.
+
+{% code title="appsettings.json" %}
+
+```json
+{
+  ...
+  "Umbraco": {
+    "Commerce": {
+      "Deploy": {
+        "PaymentMethods": {
+          "IgnoreSettings": [ "liveApiKey", "testMode" ]
+        },
+        "ShippingMethods": {
+          "IgnoreSettings": [ "liveApiKey", "testMode" ]
+        },
+        "TaxCalculationMethods": {
+          "IgnoreSettings": [ "liveApiKey", "testMode" ]
+        }
+      }
+    }
+  }
+  ...
+}
+```
+
+{% encode %}
+
+For each supported entity type, you can supply an `IgnoreSettings` option, which contains an array of aliases of the settings options to be ignored.
