In Xano, head over to the "API" section on the left sidebar. Click that "Add API" button. Give your API a name, then hit "Create API". Inside your shiny new API, click on "Endpoints" in the left sidebar. Then, click the "Add Endpoint" button. You'll need to pick a type of endpoint; go with "Custom". Set the path for your endpoint. If you want it to be dynamic, use curly braces `{}` around the dynamic parts. For example, `/user/{id}`. This way, you can capture the value in the path. Click on the `Input` tab. Here, you can define what kind of inputs your endpoint will accept. For dynamic endpoints, make sure to define corresponding variables for the dynamic parts. For instance, add a new parameter named `id` and set its type to "Number" or "String" as needed. Head over to the `Logic` tab. This is where you'll define the behavior of your endpoint. You can add various functions like queries, loops, conditionals, etc. If you need to use the dynamic parameter, just refer to it by using the variable syntax `{{id}}`. Add the necessary database interactions by dragging and dropping actions like "Query All Records," "Create Record," etc. to the logic flow. To filter or modify data based on the dynamic part of the URL, use the dynamic parameter in your logic. For example, if you are querying user data, set the condition to query where `id` equals `{{id}}`. Once your endpoint logic is complete, click on the `Test` tab. Enter a value for the dynamic parameter and run the test. You should see the appropriate response based on the logic you have set up. If your endpoint requires authentication, go to the `Security` tab and configure the necessary authentication rules. This may include API keys, user sessions, or other forms of authentication. Save your endpoint settings. Make sure to click the "Save" button to save all the changes. Your dynamic API endpoint is now ready for deployment and can be used in your applications.
