## IAuthServiceJwtValidator Interface

Validates JWTs minted by this authorization server itself \(its own access tokens, refresh

### Methods

## IAuthServiceJwtValidator\.ValidateAsync\(string, ValidationOptions\) Method {#Abblix.Oidc.Server.Features.Tokens.Validation.IAuthServiceJwtValidator.ValidateAsync(string,Abblix.Jwt.ValidationOptions)}

Asynchronously validates a JSON Web Token \(JWT\) based on the provided validation options\.
This method ensures that the JWT is correctly formatted, signed, and adheres to the expected claims and audience\.

```csharp
System.Threading.Tasks.Task<Abblix.Utils.Result<Abblix.Jwt.JsonWebToken,Abblix.Jwt.JwtValidationError>> ValidateAsync(string jwt, Abblix.Jwt.ValidationOptions options=Abblix.Jwt.ValidationOptions.Default);
```
#### Parameters

###### `jwt` [System\.String](https://learn.microsoft.com/en-us/dotnet/api/system.string 'System\.String') {#Abblix.Oidc.Server.Features.Tokens.Validation.IAuthServiceJwtValidator.ValidateAsync(string,Abblix.Jwt.ValidationOptions).jwt}

The JWT string to be validated\.

###### `options` [ValidationOptions](https://www.abblix.com/en/docs/api/abblix-jwt/Abblix.Jwt.ValidationOptions 'Abblix\.Jwt\.ValidationOptions') {#Abblix.Oidc.Server.Features.Tokens.Validation.IAuthServiceJwtValidator.ValidateAsync(string,Abblix.Jwt.ValidationOptions).options}

The validation options that control how the JWT is validated, including checks for issuer,
            audience, expiration, and more\. Defaults to [Default](https://www.abblix.com/en/docs/api/abblix-jwt/Abblix.Jwt.ValidationOptions#Abblix.Jwt.ValidationOptions.Default 'Abblix\.Jwt\.ValidationOptions\.Default') if not specified\.
