+# Using data provider for getting available locales in active channel for shop user
+
+* Status: proposed
+* Date: 2021-07-05
+
+## Context and Problem Statement
+Customer should have access only to locales available in their channel
+
+## Considered Options
+
+### Using Doctrine Collection extension
+
+* Good, because consistent with actual approach to modifying responses content
+* Good, because works with rest of API extension like pagination
+* Bad, because locales don't have relation to channel, so using Doctrine Collection extension is extremely hard.
+
+### Using Data Provider
+
+* Good, because we already have this approach for older resources
+* Good, because easy to implement 
+* Bad, because using data providers omits extra Doctrine extensions like pagination
+
+## Decision Outcome
+
+Chosen option: Using Data Provider
+Shops shouldn't have many locales for each channel, so lack of a pagination is smaller problem than creating overcomplicated query in Doctrine Collection extension
