# Validate a JWT

If you’re having trouble authenticating your clients, you can validate your JSON Web Token (JWT) in the [Document Engine dashboard](https://www.nutrient.io/guides/document-engine/management/dashboard.md). This lets you check if you’re missing any claims and if your JWT is in the correct format.

If you’re testing Document Engine locally, you can follow the [setting up Document Engine](https://www.nutrient.io/sdk/document-engine/getting-started.md) guide and access the JWT validator at http://localhost:5000/dashboard/jwt-validation. To use it, paste the JWT into the text field. The validation result appears instantly.
