Discover how to leverage Xano's field-level validation tools to keep your project data accurate and reliable. Dive into our detailed step-by-step guide for top tips and methods.
Xano's field-level validation tools are a game-changer for keeping data clean, thanks to their ability to enforce rules right in the backend. Set criteria for each field, and the system will automatically verify conditions like data type, format, length, and uniqueness before saving or processing. This boosts data consistency and makes catching errors simpler. Knowing how to set up and use these validations can save tons of time and head off potential data issues in your app.
Head over to your Xano dashboard and find the project with the API endpoint you want to tweak. Click on that endpoint to open it up.
In the endpoint editor, look for the "Input" tab on the left. Give it a click to see the Input schema options.
If the field you want to validate is already there, just click on it to edit. Need a new field? Hit the "Add Field" button and set up the field's name and type.
In the field configuration panel, scroll down until you see the "Validation" section. Flip the switch to turn on validation.
Once validation is on, you'll see a bunch of rules you can set. Depending on the field type, you might see options like:
Turn on and set up the rules you need.
After setting up the validation rules, don't forget to click "Save" or "Update" to lock in your changes.
Go back to the API endpoint and test it out by sending different requests. Make sure the validation rules work and that bad data gets rejected with the right error messages.
Each step helps you set up solid field-level validation in Xano, making sure your data is clean and meets the rules before it gets processed.
