+  tags:
+    - Sources
+  description: >-
+    This API replaces the current entitlement request configuration for a source.
+    This source-level configuration should apply for all the entitlements in the source.
+
+
+    Access request to any entitlements in the source should follow this configuration unless a separate
+    entitlement-level configuration is defined.
+
+    - During access request, this source-level entitlement request configuration overrides the global organization-level configuration.
+
+    - However, the entitlement-level configuration (if defined) overrides this source-level configuration.
+
+
+    A token with ORG_ADMIN, SOURCE_ADMIN, or SOURCE_SUBADMIN authority is required to call this API.
