# Service Configuration

## Credentials

Use the *Credentials* tab to view or change the authentication credentials for the query service.

![WireBootstrap Query Service Credentials](/files/-MbdC0YL1H0jgxNIrAvZ)

The service credentials for the query service need to be presented on each request to the service.  Visit [Sample Project](/query-service/sample-project.md) for examples on setting up data sources with service credentials for executing queries against a database.  Visit [Connecting to Data](https://docs.wirebootstrap.com/wirebootstrap/connecting-to-data/data-connectors) for more on data sources in general.

The *Service Id* is the API equivalent to a user name in an application.  It is the unique identifier for the service used for settings in the query service and to reference the service in API requests to the service.

The *Secret Key* is the API equivalent to an application password.  In combination with the Service Id, it is used to authenticate each service request.

## Data File

The query service configuration file is stored in the installation root in a JSON file called `wire-qs-service.json`.  An example of the contents of the file is below.

```javascript
{
  "Service": {
    "Id": "qs_ebi-appdev2",
    "Key": "WireBootstrap$"
  },
  "Providers": [
    {
      "Id": "MSSQL",
      "Name": "Microsoft SQL Server",
      "Type": "MSSQL",
      "DataSourceType": 1,
      "ConnectionString": "Data Source=%server%%port%;Initial Catalog=%database%;Integrated Security=%integratedsecurity%;User Id=%user%;Password=%password%;Connect Timeout=6"
    }
  ]
}
```

The `Service` property contains the Service Id and the Secret Key values for the service.

The `Providers` array contains one object which contains the Microsoft SQL Server provider connection details.  With the exception of the `ConnectionString` property, **these values should not be changed**.

The `ConnectionString` property is a template for the connection string used to connect to SQL Server databases by the query service.  The variables, denoted as keywords surrounded by percent signs (%), will be changed at run-time per the settings in a given [data service connection](/query-service/administration/data-connections.md) presented in query requests from clients.  This template can be changed (with caution) to meet specific connection string requirements for a target database service.

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

Perform an HTTP GET request on the current page URL with the `ask` query parameter, and the optional `goal` query parameter:

```
GET https://docs.wirebootstrap.com/query-service/administration/service-configuration.md?ask=<question>&goal=<endgoal>
```

`ask` is the immediate question: it should be specific, self-contained, and written in natural language.
`goal` is optional and describes the broader end goal you are ultimately trying to accomplish on behalf of the user. GitBook uses it to tailor the answer towards what is most useful for that goal.

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.
