# RestSharp Authenticator

To register a specific <mark style="color:blue;">**RestSharp**</mark> credential, just create that type and assign the appropriate Authenticator.

```csharp
CredentialStore.RegisterRefresh("ClientAPI", (o) => {

        return new RestSharpCredentialStoreItem(
                new RestSharp.Authenticators.JwtAuthenticator("MyToken"), 
                DateTimeOffset.UtcNow.AddMinutes(58));
        
});
```

Any time you create a client, simply assign this credential authenticator:

```csharp
var rco = new RestClientOptions("https://localhost.com")
{
    //Assign the CredentialAuthenticator with the name tied to the refresh
    Authenticator = new CredentialAuthenticator("ClientAPI")
};

//Create a new client
using var client = new RestClient(rco);

//Anytime you execute any requests, it's automatically maintained. 
```

## Querying This Documentation
If you need additional information that is not directly available in this page, you can query the documentation by asking a question.

Perform an HTTP GET request on the following URL with the `ask` and `goal` query parameters:

```
GET https://docs.perigee.software/core-modules/credential-management/restsharp-authenticator.md?ask=<question>&goal=<user_goal>
```

`ask` is the immediate question: it should be specific, self-contained, and written in natural language.
`goal` is what the user is ultimately trying to achieve, the reason they need the answer. Sharing it helps GitBook give you a better, more relevant answer. A goal is most helpful when it describes the outcome the user wants rather than restating the question. For example, with `ask=how do I create an API token`, a goal like `automate deployments from our CI pipeline` lets GitBook tailor the answer to that use case.

The response will contain a direct answer to the question and relevant excerpts and sources from the documentation.

Use this mechanism when the answer is not explicitly present in the current page, you need clarification or additional context, or you want to retrieve related documentation sections.
