+# Announcing "Ignore Duplicate Writes" in OpenFGA
+
+We've added two new optional parameters to the Write API endpoint to improve the experience of writing data to FGA. You can now gracefully ["ignore" duplicate writes and missing deletes](https://openfga.dev/docs/getting-started/update-tuples#05-ignoring-duplicate-or-missing-tuples).
+
+## The Problem
+
+When you're writing tuples to OpenFGA, it's almost inevitable that you'll try to write a relationship tuple that already exists (e.g., `user:anne` is already a `viewer` of `document:123`) or try to delete one that's already gone. In the past, OpenFGA would reject the entire Write request containing that single duplicate operation.
+
+This forced developers to build complex error-handling and retry logic on the client-side, just to filter out the single problematic tuple and resend the rest of the batch. This adds latency and operational overhead.
+
+## The Solution
+
+The Write API now accepts two new optional parameters to gracefully handle these use cases:
+
+- **`on_duplicate: "ignore"`**: When included in the `writes` section, this tells OpenFGA to simply skip any tuples that already exist instead of failing the request.
+
+- **`on_missing: "ignore"`**: When included in the `deletes` section, this tells OpenFGA to skip any tuples that don't exist.
+
+Now, you can send large batches of writes and deletes without worrying about these common conditions breaking your import.
+
+## See it in Action
+
+For writes:
+
+<WriteRequestViewer
+  relationshipTuples={[
+    {
+      user: 'user:anne',
+      relation: 'viewer',
+      object: 'document:roadmap'
+    },
+  ]}
+  conflictOptions={{
+    onDuplicateWrites: 'ignore',
+  }}
+  skipSetup={true}
+  allowedLanguages={[
+    SupportedLanguage.JS_SDK,
+    SupportedLanguage.GO_SDK,
+    SupportedLanguage.DOTNET_SDK,
+    SupportedLanguage.PYTHON_SDK,
+    SupportedLanguage.JAVA_SDK,
+    SupportedLanguage.CLI,
+    SupportedLanguage.CURL,
+  ]}
+/>
+
+And deletes:
+
+<WriteRequestViewer
+  deleteRelationshipTuples={[
+    {
+      user: 'user:anne',
+      relation: 'owner',
+      object: 'document:roadmap'
+    },
+  ]}
+  conflictOptions={{
+    onMissingDeletes: 'ignore',
+  }}
+  skipSetup={true}
+  allowedLanguages={[
+    SupportedLanguage.JS_SDK,
+    SupportedLanguage.GO_SDK,
+    SupportedLanguage.DOTNET_SDK,
+    SupportedLanguage.PYTHON_SDK,
+    SupportedLanguage.JAVA_SDK,
+    SupportedLanguage.CLI,
+    SupportedLanguage.CURL,
+  ]}
+/>
+
+## Get Started
