• Log in to your Xano account.
• On the left-hand sidebar, click on the API section. This will bring up the API groups you have.

• If you don't have an API group yet, click on Create API Group at the top.
• Name your API Group and provide a description if you like, then click Save.

• Within the API group, click on Endpoints in the sidebar.
• Click on the + Add Endpoint button.
• Specify the endpoint path and method (e.g., GET /products).

• Define the main route logic in the endpoint by selecting or creating a query, function, or other logic to process the request.
• Save the endpoint and test it to ensure it works as expected.

• Go back to the Endpoints section within the same API group.
• Click the + Add Endpoint button to create a new endpoint.
• Define the path where you want your nested route to live. For example, if the main route is /products, you can create a sub-endpoint like /products/{product_id}/reviews.
• Set the method (e.g., GET, POST, PUT) for the endpoint.

• In the endpoint path, use wildcards (e.g., {product_id}) where dynamic values will be passed.
• These wildcards will automatically be available as input parameters in your endpoint logic.

• Like the main route, add the necessary logic to process the nested route.
• For example, in the /products/{product_id}/reviews endpoint, you might retrieve reviews for the specific product_id.
• Utilize input parameters like {product_id} within your queries, functions, or custom logic.

• Save the newly created nested route endpoint.
• Test the nested route endpoint by making requests with actual data (e.g., /products/1/reviews) to ensure it behaves as expected.

• Repeat the process of creating additional nested routes if required.
• Continue to test each new nested route to make sure they interact properly with the main route and other nested routes.

• Once your nested routes are set up and tested, create appropriate documentation for your API.
• Ensure you explain how each endpoint and nested route works, including the necessary parameters and expected responses.

By following these steps, nested routes in Xano can be created efficiently and organized logically to meet various API requirements.
