+Private APIs are deployed as [**Cloud Functions**](https://firebase.google.com/docs/functions) within your Firebase project. While deploying, you can configure the following options:
+
+- **Use Custom Name for Cloud Function**: When enabled, allows you to specify a custom name for the deployed Cloud Function. By default, this option is disabled and Cloud Function is named as `ffPrivateApiCall`.
+- **Private API Cloud Function Instances**: You can configure the number of Cloud Function instances to optimize performance and manage costs.
+    - **Min Instances**: Set the minimum number of active instances to reduce latency and avoid cold starts. Setting this value greater than 0 will keep instances warm but may incur additional costs.
+    - **Max Instances**: Define the maximum number of instances that can be scaled up based on demand.
+    
+    **Note**: To minimize costs, you can set the **Min Instances** value to 0. For detailed pricing information, refer to the [**Cloud Functions Pricing page**](https://cloud.google.com/functions/pricing-overview).

 ### Process Streaming Response
 
 When working with APIs that send data continuously, like Server Sent Events (SSE), you can enable this option. This ensures your app can handle the ongoing flow of data over a long-lasting HTTP connection to display real-time updates.
