+#### Conflict Options for Write Operations
+
+The SDK supports conflict options for write operations, allowing you to control how the API handles duplicate writes and missing deletes.
+
+> **Note**: This requires OpenFGA [v1.10.0](https://github.com/openfga/openfga/releases/tag/v1.10.0) or later.
+
+##### Using Conflict Options with Write
+```javascript
+const options = {
+  conflict: {
+    // Control what happens when writing a tuple that already exists
+    onDuplicateWrites: OnDuplicateWrites.Ignore, // or OnDuplicateWrites.Error (the current default behavior)
+    // Control what happens when deleting a tuple that doesn't exist
+    onMissingDeletes: OnMissingDeletes.Ignore, // or OnMissingDeletes.Error (the current default behavior)
+  }
+};
+
+const body = {
+  writes: [{
+    user: 'user:anne',
+    relation: 'writer',
+    object: 'document:2021-budget',
+  }],
+  deletes: [{
+    user: 'user:bob',
+    relation: 'reader',
+    object: 'document:2021-budget',
+  }],
+};
+
+const response = await fgaClient.write(body, options);
+```
+
+##### Using Conflict Options with WriteTuples
+```javascript
+const tuples = [{
+  user: 'user:anne',
+  relation: 'writer',
+  object: 'document:2021-budget',
+}];
+
+const options = {
+  conflict: {
+    onDuplicateWrites: OnDuplicateWrites.Ignore,
+  }
+};
+
+const response = await fgaClient.writeTuples(tuples, options);
+```
+
+##### Using Conflict Options with DeleteTuples
+```javascript
+const tuples = [{
+  user: 'user:bob',
+  relation: 'reader',
+  object: 'document:2021-budget',
+}];
+
+const options = {
+  conflict: {
+    onMissingDeletes: OnMissingDeletes.Ignore,
+  }
+};
+
+const response = await fgaClient.deleteTuples(tuples, options);
+```
+
+##### Conflict Options Behavior
+
+- **`onDuplicateWrites`**:
+  - `OnDuplicateWrites.Error` (default): Returns an error if an identical tuple already exists (matching on user, relation, object, and condition)
+  - `OnDuplicateWrites.Ignore`: Treats duplicate writes as no-ops, allowing idempotent write operations
+
+- **`onMissingDeletes`**:
+  - `OnMissingDeletes.Error` (default): Returns an error when attempting to delete a tuple that doesn't exist
+  - `OnMissingDeletes.Ignore`: Treats deletes of non-existent tuples as no-ops, allowing idempotent delete operations
+
+> **Important**: If a Write request contains both idempotent (ignore) and non-idempotent (error) operations, the most restrictive action (error) will take precedence. If a condition fails for a sub-request with an error flag, the entire transaction will be rolled back.

-         * The Write API will transactionally update the tuples for a certain store. Tuples and type definitions allow OpenFGA to determine whether a relationship exists between an object and an user. In the body, `writes` adds new tuples and `deletes` removes existing tuples. When deleting a tuple, any `condition` specified with it is ignored. The API is not idempotent: if, later on, you try to add the same tuple key (even if the `condition` is different), or if you try to delete a non-existing tuple, it will throw an error. The API will not allow you to write tuples such as `document:2021-budget#viewer@document:2021-budget#viewer`, because they are implicit. An `authorization_model_id` may be specified in the body. If it is, it will be used to assert that each written tuple (not deleted) is valid for the model specified. If it is not specified, the latest authorization model ID will be used. ## Example ### Adding relationships To add `user:anne` as a `writer` for `document:2021-budget`, call write API with the following  ```json {   \"writes\": {     \"tuple_keys\": [       {         \"user\": \"user:anne\",         \"relation\": \"writer\",         \"object\": \"document:2021-budget\"       }     ]   },   \"authorization_model_id\": \"01G50QVV17PECNVAHX1GG4Y5NC\" } ``` ### Removing relationships To remove `user:bob` as a `reader` for `document:2021-budget`, call write API with the following  ```json {   \"deletes\": {     \"tuple_keys\": [       {         \"user\": \"user:bob\",         \"relation\": \"reader\",         \"object\": \"document:2021-budget\"       }     ]   } } ```

The API is not idempotent by default: if, later on, you try to add the same tuple key (even if the `condition` is different), or if you try to delete a non-existing tuple, it will throw an error. To allow writes when an identical tuple already exists in the database, set `\"on_duplicate\": \"ignore\"` on the `writes` object. To allow deletes when a tuple was already removed from the database, set `\"on_missing\": \"ignore\"` on the `deletes` object. If a Write request contains both idempotent (ignore) and non-idempotent (error) operations, the most restrictive action (error) will take precedence.
