Alright, first things first. Head over to your Xano workspace and find the API module where you want to add those validation rules. Once you're there, look for the specific API endpoint you want to tweak and give it a click.

Now, within that API endpoint, you'll see an 'Input' tab. Click on it. This is your playground for defining the parameters your API endpoint will accept.

Next up, hit 'Add a Parameter' to start defining what kind of input your API should expect. You'll need to specify the Name, Type, and any other required fields for each parameter you want to validate. Easy peasy, right?

For each parameter, find the 'Validation' tab or section. Here, you can set up various validation rules like:

• Required: Tick this box if the parameter is a must-have.
• Minimum/Maximum length: Set the limits for string inputs.
• Minimum/Maximum value: Define the numeric boundaries for numerical inputs.
• Type validation: Make sure the parameter matches the expected type (string, number, date, etc.).
• Custom Validation: Add any custom logic using conditional statements. Get creative!

Once you've set up all the validation rules, click on the 'Save' button at the top or bottom of the page. Now, it's time to test your API endpoint. Make different API requests and check if the validation rules are working as they should. Fingers crossed!

Finally, review and configure how the API should handle validation errors. Xano usually provides default error messages for common validations, but you can customize these error responses in the 'Response' section of the API endpoint. Make it as user-friendly as possible.

And there you have it! Follow these steps to effectively configure API request validation rules in Xano.
