How to create API endpoints in Xano

Creating API endpoints in Xano is a breeze, but if you’re new to it, it might seem a bit daunting. No worries; this guide will walk you through everything you need to know. Follow these steps to make your backend as powerful and versatile as you need it to be.

Step 1: Set Up a Project

First things first, you need to set up a project in Xano. Log in to your Xano account, and from the dashboard, click on "New Workspace". Give it a name that makes sense for your project (maybe something like "MyAPI").

Step 2: Define Your Database Tables

API endpoints need data, so let's set up a database table. Navigate to the "Database" section:

1. Click on "New Table".
2. Name your table. For instance, if you're creating a user management system, "Users" could be a good name.
3. Add columns to your table. Add fields like id, name, email, and password.

Here's a tip: Use appropriate data types for each field. For example, for emails, use Text, and for the id, you could use Integer.

Step 3: Create API Endpoints

Now, the fun part! Let's create API endpoints.

1. Head over to the "API" section and click on "New API Endpoint".
2. Select the method (GET, POST, PUT, DELETE). For instance, a GET request might be used to retrieve user data.
3. Name your endpoint something meaningful, like "/getUsers".
4. Next, you'll define the logic.

Example: Creating a GET Endpoint

• GET /getUsers
  • Click on "Add Step" and select "Database Query".
  • Choose the "Users" table.
  • Add any filters you need (e.g., only showing active users).

Example: Creating a POST Endpoint

• POST /createUser
  • Click on "Add Step" and select "Database Insert".
  • Again, choose the "Users" table.
  • Map your input parameters (name, email, and password) to the corresponding fields.

Step 4: Test Your Endpoints

Testing is crucial to ensuring your API works as expected. Xano makes it super easy to test your endpoints right in the dashboard.

1. Go to the "API" section.
2. Select your endpoint and click on the "Test" button.
3. Enter any necessary input parameters and hit "Run Test".

Check the response to see if the data is coming back correctly or if there are any errors.

Step 5: Handle Authentication

For most applications, securing your API is essential. Xano provides built-in options for user authentication.

1. Navigate to "Authentication" under your API group settings.
2. Select "New Auth Scheme" and choose a method like "JWT".
3. Apply this scheme to the endpoints you wish to secure.

Step 6: Deployment

Once you’ve tested and secured your API endpoints, you’re ready to deploy. Xano endpoints are ready for production use as soon as you create them. Simply share the endpoint URL with your front-end team or start using them in your applications.

Conclusion

That’s it! You've successfully created and tested API endpoints in Xano. Whether you're building a complex SaaS application or a simple website, Xano simplifies backend tasks, letting you focus on what matters most—building awesome features. Happy coding!
